1. Characteristic of Induction MotorThe induction motor is classified into a single-phase

motor and a three-phase motor according to the using

power source. This motor always uses both auxiliary

winding and condenser not only when starting but

also during operation. Generally speaking, its starting

torque is not so great, but its structure is simple and

reliable. In addition, its connection is simple. It is

suitable to use in houses and on factories. For a

single-phase induction motor, be sure that the

condenser indicated in the name plate should comply

with the capacity of the motor.

For a single-phase induction motor, it is not possible

to reverse the direction of rotation within a short time

during operation because of the inertia torque exerting

adversely against the direction the motor is supposed

to change to. Thus, stop the motor first and change

the rotational direction next. In case you do not, the

motor can be damaged.

The power source of a single-phase motor includes U

(100V 60.60Hz), C (200V 50/60Hz, 220V 50/60Hz,

230V 50Hz). Refer to (Fig. 1).

The three-phase induction motor has simpler

connection, and higher efficiency and reliability than

the single-phase motor, because it can be driven by a

three-phase power source directly. The three-phase

motor is popular as a general-purpose motor. The

power source for a three-phase motor includes H

(220V 50/60Hz), M (380V 50/60Hz), Z (440V

50/60Hz). Refer to (Fig. 2).

It is possible to use the motor for continuous rated

operation.

It is designed to be used in a single direction.

The number of rated revolution of the motor varies

depending on the load imposed on it.

xIt is suitable for such operation that does not need

the speed control.

Its insulation class is E. Our UL conformance motor is

class A.

2. Characteristic of Rotation and TorqueUnder a constant voltage, the relationship between

the number of rotation and the torque is as shown in

(Fig. 3). With no-load, the number of rotation roughly

approximates the number of synchronous rotation,

but as the load increases, the number of rotation

decreases and reaches the torque TL The stable

zone is to this point.

When the load is further increased and over the point

TM, that is, the torque of the motor reaches the

unstable zone, the motor stops and restriction

electricity runs. As a result, the motor generates high

heat, and then it can be damaged. Therefore, a safe

operation is possible if only the motor is used within

the stable zone of the load.

3. Characteristic of Voltage and CondenserThe characteristic of voltage can be represented by

the torque's characteristic about the applied voltage.

The torque of induction motor changes in proportion

to two times the voltage.

The characteristic of torque also change according to

the capacity of the condenser.

As the capacity of the condenser boost, the starting

torque and stalling torque increase. But if the capacity

is increased by 2.5~3.0 folds, the operating torque

decreases and the starting torque do not increase.

As a simple method to increase the torque when the

induction motor is short on torque, either the voltage

or the condenser capacity can be increased to

continue the operation. In this case, the loss input of

the motor increases and the temperature rises

rapidly.

However, if the motor must be run with insufficient

torque, take measures to let the motor release heat

as much as possible and operate the motor while

keeping the temperature of the motor's housing below

90 Refer to (Fig. 4).

1. Characteristic of Reversible Motor

The reversible motor is a condenser type single-phase induction

motor. Therefore, its general characteristics are as same as

those of the induction motor.

It is possible for the motor to operate in rotational direction from

normal - stop - to reverse.

The reversible motor has a temporary brake device built inside

the motor to facilitate the operation in normal as well as reverse

direction. Also, the mail and sub windings of the stator have their

windings manufactured with the same method to guarantee the

identical characteristics between them. Refer to (Fig. 2).

Also, it has a higher starting torque to facilitate the frequent

changes in rotational direction from normal direction to reverse

direction, and vice versa, within a short time. Refer to (Fig. 3).

The temporary brake is employed to prevent overrun. The

temporary brake has a little retaining force to provide excellent

instantaneous stop by preventing overrun when stopping. Refer

to (Fig. 1).

The changeover switch can help the motor reverse its rotational

direction easily within a short time so that it is suitable for such

operation that changes the rotational direction frequently from

normal to reverse, and vice versa. Therefore, this motor is called

a reversible motor.

Since the design characteristic of the reversible motor is a

capability to control the directional changes in rotation, the loss

input is larger and the temperature can rise higher compared with

the induction motor. Hence, the rated operating time is limited to

30 minutes.

Thus, 30 minutes of rated operating time means that the motor at

the rated load can have at least 30 minutes of non-stop operation

within the safe upper limit of the temperature rise. It is possible for

the motor at the intermittent load or at the light load to have non-

stop operation, if only the outer cover temperature is not over 90

.

In general, the reversible motor is as same as the induction

motor in terms of the number of rotation, and the characteristics

of torque, voltage, and condenser.

2. Temporary Brake StructureThe temporary brake of the reversible motor has

characteristics as follows.

Apply a frictional load to improve the frequent reversal

operation.

Reduce overrun.

Provide a little holding torque.

Structurally, as shown in (Fig. 1), the brake block is forcedtoward the brake wheel by a spring to make retention force.Since at the aspect of the structure of the brake as shownthe above it has a limitation to strengthen retention force,we adjusted the brake power to be about 10% of the motoroutput torque.The figures representing the holding torque and theoverrun under no-load in (Table 1) may have more or lessdeviations for each motor. They may also have somediscrepancies depending on the operating duration and theambient temperature. It is advised therefore that the tablefigures should be used only for reference purpose.The rated torque and electric current of the reversiblemotor were measured in the circumstance where thetemporary brake block is installed in the motor. Therefore,there will be no problem even if the corresponding tablefigures are used when selecting a motor. The conservativeselection of a motor is recommended, however, becausethe figures may have some deviation depending on thebrake block employed for the motor.Care should be given, because there is a case that theholding toque may fall below the figures of (Table 1) in theinitial phase of operation.

3.Operating Time and Temperature Rise Although 30 minutes of rated operating time is specified for the

reversible motor, the rated operating time may change

depending on the operation conditions if the operation

frequently repeats stop and run (On-Off) within a short period of

time.

If the reversible motor frequently repeats stop and run (On-Off)

within a short time, the starting current gets increased to cause

the motor temperature to rise. However, the longer rated

operating time may be obtained by allowing the motor to

remain stop longer, because the stoppage can provide a

chance of natural cooling for the motor to decrease its

temperature.

The conditions of the intermittent (On-Off) operation are

determined as shown in A ~ F of (Fig. 4). F stands for

continuous operation.

The characteristics shown in (Fig. 5) through (Fig. 8) represent

the measurements of the motor for 220V 50/60Hz. Naturally,

the characteristics of the motor or 220V 60Hz will have a little

greater characteristic values because of a voltage increased by

about 10%, and therefore, the recommendation is that the

motor should be operated at the temperature below the ambient

temperature.

The temperature rise measurement is performed

when the motor, under no-load, is prevented rom

transferring its internal heat to the outside through the

motor's external contact points using thermograph.

This method of measurement can provide the highest

possible temperature rise.

Especially, if either a load or an inertia load is greater

than the motor's rated torque, the longer time is

required for start or directional reversal, resulting in a

greater temperature rise, which requires a user's

attention.

The specified temperature rise of the reversible motor

is 75 ( T value) in general, and be careful not to

exceed the temperature.

In reality, there is a case that the motor alone is used,

but mostly the motor is used in combination with the

gearhead. Hence, when the motor of K8RG25N is

used with no-load in combination with the gearhead of

K8G50B, the temperature rise is like a L curve shown

in (Fig. 8) and also the temperature rise becomes

lower and the operating time becomes longer by

about 30 minutes as compared with the motor shown

in (Fig. 6).

Although the principle is to keep the coil temperature

below the specified temperature for the insulation

class. It is possible to continue the operation if the

motor housing surface temperature remains less than

90 . The temperature of the motor varies depending

on the load, operating cycle, motor's mounting

method, and ambient temperature.

1. Characteristic of Terminal Box Type Motor

The motor's charging section including lead wire is

made airtight by the terminal box to provide the

protection from the dust and moisture.

Therefore, the motor can be used in the harsh

environment.

The classification of the device protection structure for

our T type terminal box motor is IP54.

The motor features a compact design.

The ground terminal is attached to the motor.

However, Type (6~15W) of the single-phase induction

motor does not have a built-in ground inside the

terminal box.

Since the motor is so structured as to make the piping

work easier, it is excellent in connection work. The

cable is firmly fixed to provide the stronger tension

when wiring the cable.

The terminal box cover is made of PC resin which is

excellent in insulation and stiffness.

The T type terminal box uses a product that provides

high reliability.

Please use AWG NO. 24 ~ AWG NO. 10 (0.25 mm2

~ 4.0 mm2) for the lead wire. At this time, the length of

the peeled-off lead wire should be about 8mm.

Gearhead and decimal gearhead are sold separately. The code in of gearhead model is for gear ratio.

color indicates that the output shaft of the geared motor rotates in the same direction as the output shaft of the motor. Others indicate rotation in the opposite direction.

If you are to have less ratio than the ratio in the table, you can install the decimal gearhead, which has one tenth of the ratio, between the gearhead and the motor. In this case,

the permissible torque is 20N m/200kgfcm.
