BASIC ELECTRICAL MACHINES

TRAINING SYSTEM

ELECTRICAL MACHINES TECHNOLOGY MODULE

The common objective guiding the design of this equipment is the development of tools that are the core of training programs about the latest

manufacturing and service technologies and techniques.

In following these programs the students acquire theoretical knowledge and practical experience on machines that are basically of an industrial

type, but so arranged as to provide maximum learning profitability to them.

Also great attention has been given to the human interface to provide a system that is safe, user friendly, easy to understand, continuously

updated and tuned to the actual industrial, real life world.

Some of the design features that provide our equipment with an outstanding training value are described below.

CONSTRUCTION

The ELECTRICAL MACHINES TRAINER provides a complete range of integrated teaching equipment for the various subjects of both AC and

DC machines. All equipment is implemented in rugged enclosures. The modules can be optionally mounted on an alluminium frame, when being

exercised or when stored, and can be used both for individual or for group demonstration purposes. The machines within the same power range

are fully compatible among them, both mechanically and electrically. They can be easily and quickly assembled on a test board that ensures safe

coupling and noiseless, smooth and vibration free running. Educational boards with 4 mm safety terminals and printed electrical diagrams are

mounted on each machine.

Half-coupling joints are provided with shock absorbers and rotating parts are covered with protection guards.

Different types of brakes and dynamometers are available for controlling and measuring the loads of the motors under test.

Torque measuring is bi-directional by means of a mechanical levelling system or a thin film strain gauge load cell. Speed and torque readings are

normally digital. However, analog, or analog-digital instruments are available on request.

A computerized electrical machine test system is available to read and process the parameters of machines under test. By entering data

manually the tests can be simulated. Brakes are sized for a breaking power greater than the overload power of the motors.

Power range of the machines, and therefore power requirements, can vary from the S series (fractional Horse Power), to the M series

(approximately 1 KW) and the L series (up to 5 Kw). For the operation of a typical experimental group, a bench with a working area of 2000 x

700 mm is required.




Rev 04.15

EXPERIMENTAL GROUPS

Several different experimental groups can be selected by the user, each group using the same power supply, loads and control/accessory

modules. The attached selection matrix may be used to identify the essential and the recommended items required to provide complete

experimental components for each type of machine.

Each electrical machine test bench is normally intended for 3 to 4 students groups, but can be easily handled by two. The system requires a

three-phase supply, 5 wire, 220/380 V, 50 Hz (or according to local voltages).

SAFETY

Our power supply is provided with built-in differential, earth leakage and magneto-thermal protections that ensure a safe operation and

protection of the equipment against damages caused by incorrect use. An over-speed protection is available on request.

Electrical connections are performed via 4 mm safety cables and terminals. Use of our set of cables is recommended

FLEXIBILITY AND COMPATIBILITY The instruments provided are electrically compatible with the various machines of the range. Load modules can be connected in

series, parallel, delta and star with no limitation, and are suitable for testing generators and transformers even in overload conditions

TEACHING LEVEL

The flexible and modular design enables to select a wide range of electrical machines test methods, varying in complexity from simple motor

load test up to fully automated PC based measurement and control system.

Therefore the teaching level can vary from the technician level up to graduate level and researcher.

EXPANSIONS AND INTERFACING

The electrical machines test systems can be integrated with our power electronic drivers for open or closed loop speed control of DC motors and

variable speed control of AC motors. Included are computer interfaces for real time monitoring and control techniques under varying load

conditions

ORIGIN

Our electrical machines and accessories are manufactured in Italy.

COURSEWARE

An experiment manual is provided which contains, for each experiment, a theoretical review, circuit diagrams, experiment

execution procedure in a step by step approach and worksheets for tabling and graphing the experiment results. Some of the

typical experiments covered are listed below (others can be designed by the user as necessary).

COMPUTER BASED SYSTEM

In alternative to the manual test system, the above experiments can be executed with a computer based system. In this case the electrical

machines are connected to a data acquisition box that communicates with a personal computer. The parameters of the tests are read directly

into the computer where they are processed for presentation in tables and graphs.

The experiments can also be simulated by entering data manually through the PC keyboard. Four software programs are available for testing

Transformers, AC Asynchronous Machines, AC Synchronous Machines and DC Machines respectively

ADVANTAGES The following are the distinct advantages of the SAMAR test systems:

Any machine can be coupled with any other. Due to the unique SAMAR motor fastening system, the position of the machine shaft on the three

axes (X, Y and Z) can be easily and precisely adjusted. By means of a simple kit of accessories it is possible to mechanically couple any machines

of the same power range, expand the laboratory possibilities and rationalise the set of equipment to avoid any unwanted duplication.

All units are designed to perfectly integrate each other. For example, the power supply is suitable for the educational machines, for the motor

and transformer kits and for the motor assembling system; the electrical machines are fully compatible with the power electronics trainer of the

electronics section

SYSTEM SELECTION

To better clarify the use of the Components Selection Table shown below, we propose an example of how a complete list of the required

equipment can be produced.

1. Course content

First of all the course subjects must be defined: in or example it is assumed that the course will cover three and single phase transformers, three

phase motors and generators, single phase motors, DC motors and generators.

2. Number of students and stations

Then, the number of students: the laboratory of our example will include 24 students, 3 per test station, therefore 8 stations will be required.

3. Parallel work or rotation

A compromise must be reached between simultaneous operation on 8 identical stations (which can simplify the laboratory supervision but

requires equipment duplication), and student rotation (which reduces the equipment need but requires careful planning). It is decided to

provide the following 8 test stations and one instrument bench

ELECTRICAL MACHINES

TRAINER REMOVABLE ELECTRICAL MACHINE SYSTEM TYPE A43.00 This Trainer consists of a set of modular components that can be assembled in different configurations to construct most rotating machines such as:

− 2 and 4 poles AC squirrel cage motor

− 2 poles AC slip ring motor

− Single phase AC capacitor motor

− Single phase AC repulsion motor

− AC synchronous motor

− AC synchronous generator

− AC/DC universal motor

− DC series excitation machine

− DC shunt excitation machine

− DC compound excitation machine

− DC independent excitation machine

The components are:

− One AC stator

− One DC stator

− One squirrel cage rotor

− One slip ring rotor and brush set

− One collector rotor and brush set

− One starting capacitor

− Coupling base

− Safety guard

The stators are permanently mounted on a coupling base on which four supports hold the rotors and brush sets. The supports are fastened by means of knobs

that can be easily removed without the need of any tool, to exchange the rotors and brushes and implement the desired configuration. A compact and

integrated laboratory is made available to perform most experiments and tests on standard electrical machines. The advantages are obviously its lower cost

compared to that of a set of discrete machines, their modularity and, owing to the complete visibility of the components, the possibility for the student to learn

the electrical and mechanical details. The windings are connected to terminal boards on top of which they are clearly identified by drawings that show the

internal logic and make their understanding and connections easy in the different possible combinations. The synchronous machine is in all respect a real

implementation and not a simulated function of the asynchronous unit. A brake generator can be easily connected coaxial to the trainer for performing load

tests. A manual supplied with the unit describes in detail the electrical connections and the mechanical assembling procedure

according to the power of the motor they will be connected to.

Two control devices are also included: one current relay whose coil can be connected in series with the main winding of the motor to close a contact at start time

and momentarily connect the start element chosen, and one pushbutton to manually perform the same operation.

As shown in the picture, a clear silk printing on the panel face identifies the elements and allows their connection in different configurations, all of them based on

the principle that a capacitor, a resistor or an inductance in series with the auxiliary winding will simulate a rotating magnetic field that is sufficient to start the

motor. Once the motor is up to speed, the auxiliary winding, if not required by the amount of the torque to be developed, may be disconnected because the

alternating field created by the main winding is sufficient to maintain the motor in rotation.

The following main starting configurations may be implemented:

- Capacitor start

- Capacitor start and run

- Capacitor start and capacitor run (2 capacitors are used)

- Resistor start

- Inductance start

- The above with manual control

- The above with automatic control

Other combinations may be implemented for demonstration and training purposes.

A manual is supplied with the unit to describe the basic connections and experiments.

A4232 - SINGLE PHASE CAPACITOR START MOTORS This is a series of educational motors that are basically industrial models especially equipped to be suitable for training. For this purpose the windings ends are


understand operation and windings connections. The rotor is a squirrel cage while the stator has two windings: the primary winding is directly connected to the

power source while the secondary winding is normally connected in series to a capacitor and the series is paralleled to the primary winding for producing a

rotating magnetic field. A second capacitor is only used to start the motor and disconnected by a centrifugal switch when the motor is up to speed. The units can

be supplied with an experiment manual which explains typical exercises that can be executed on these machines. A comprehensive set of accessories and a joint

allow easy and quick coupling with other machines or with a brake.

OPTIONAL ACCESSORIES A42CO Coupling accessories, composed of a half coupling joint and all required hardware to fasten the motor to the coupling base (or to the Universal coupling

base, to be specified when ordering) . They are required when the motor is to be coupled to a brake or other machines.

A4236 - REPULSION MOTOR The repulsion motor is a single phase motor with a collector rotor and short-circuited brushes. An alternating voltage applied to the stator, depending on the

brushes position, induces an alternating voltage in the rotor winding. If the brushes are aligned to the neutral plane no current is induced and no torque is

developed; if they are at 90° to the neutral plane, maximum current is induced but no torque is developed because the stator and rotor fluxes are in phase.

If the brushes are at some intermediate position, a torque is developed which is at maximum value when they are at approximately 70°. Their optimum position

can be determined experimentally. For education purposes the motor is equipped with a connection board with 4 mm terminals and silk printed diagram designed

for clear understanding of the internal logic and connections

BRAKES

A4410 - MAGNETIC POWER BRAKE This magnetic powder brake consists of a stator with an energising coil, an internal rotor and magnetic iron powder between them. The field generated by the

current flowing in the coil "solidifies" the magnetic powder iron that mechanically connects the rotor to the stator with a force that is proportional to the amount

of current. Therefore, by varying the energising current it is possible to vary the braking action. The torque may be displayed by the Torque Meter Model A4730

B3729-H – STAR/DELTA CIRCUIT The B3729-H simulator module replicates in a scaled and simplified manner the classic star-delta switching circuit.

This system is often used in practice to start large AC electric motors with heavy loads. The principle is to initially

connect the motor 3-phase windings in STAR mode, thus reducing the starting current.

After a few seconds the connection is changed to DELTA and the motor can then accelerate the load to its full

speed. The panel includes three pushbutton switches, which are available as inputs to the PLC. The simulated

switching circuit consists of four power contactors, represented by the lighting of the four LED lamps positioned

close to the symbol of the contactor on the front face of the unit. The LEDs are controlled by four assigned outputs

of the PLC.

The condition of the four contactors can be monitored by their respective auxiliary contacts indicated on the

synoptic drawing. These contacts are available as inputs to the PLC. The result of the various operations performed

by the PLC is indicated by the four LEDs situated in the lower part of the board.

B3729-H is supplied with a Sample Program. The students can investigate the functions of the simulator using this program, and can also develop their own

programs using the software supplied with the PLC MACHINE.

The unit comes complete with a sample program and an extensive instructions manual.

It can also be used with any suitable PLC machine, which may already be possessed by the teaching institute. The B3729-DX should be used as an interface in all

cases.

B3729-I – ROTOR RESISTANCE STARTER CIRCUIT The B3729-I simulator module replicates in a scaled and simplified manner a rotor resistance starter circuit. This

system is often used in practice to reduce the overload while starting and launching large AC asynchronous electric

motors. These motors have the rotor made of a winding, creating a magnetic circuit.

The winding is initially connected to a (relatively) high resistance, which is progressively reduced in steps to a null

value (short circuit). Due to the properties of the magnetic interaction between rotor and stator, this reduces the

current required for starting. The panel includes two pushbutton switches, which are available as inputs to the PLC.

The simulated starter circuit consists of five power contactors, represented by the lighting of the five LED lamps

positioned close to the symbol of the contactor on the front face. The LEDs are controlled by five assigned outputs

of the PLC. The condition of the five contactors can be monitored by their respective auxiliary contacts indicated on

the synoptic drawing. These contacts are available as inputs to the PLC.

B3729-I is supplied with a Sample Program. The students can investigate the functions of the simulator using this program, and can also develop their own

programs using the software supplied with the PLC MACHINE. The unit comes complete with a sample program and an extensive instructions manual.

B3601 – INDUSTRIAL ELECTRONICS TRAINER The trainer is conceived to present a review of the characteristics and use of important industrial devices for power handling/conversion, up to application

examples of special interest in comprehensive manner. The trainer consists of a collection of box-like modules, 100 x 160 x 20mm size, with a magnetic base and a

printed circuit board front face. The PCB face includes the components and devices needed to perform the experiments, with clear silkprint indicating the

component symbols, identities and interconnections.For the execution of the experiments the modules are placed on a metallic Base plate (430 x 310 x 30mm)

where they are retained by the magnetic strips. The connections to the power supply and to the measuring instruments is by plug-in cables. Certain experiments

require more than a single module to be interconnected. This is also done by plug-in cables. The magnetic latching of the modules to the metallic Base plate

ensures that the various items remain steadily fixed even if the Base plate is placed vertically, as in case of collective demonstrations by the Instructor. The trainer

includes an Auxiliary Module with the low-voltage DC and AC sources required to perform the experiments. This module also includes resistive and inductive loads.

All the experiment modules are designed to work from the low-voltages (18-36V AC and 15 to 48V DC) for increased safety. This makes the trainer especially

suitable for use by students in their early stages of training, when they have not yet gained the confidence required to work on industry-standard high-voltage

systems.
