Electric Motor Concept


Definition

Electromagnetic force ( left hand Fleming Rule )

Biggest electromagnetic force scale when direction of vertical magnetic field with current, and increases is proportional with conductor length, big of current, and magnetic field strength.


Left Hand Fleming Rule

Relation between direction of magnetic force lines, current and strength ( impulse ) always permanent like shown in to be upper. This connection called as left hand principle Fleming.

If left hand finger is bended [by] like drawing beside, hence the hand radius will show different direction.

Thumb : direction of ImpulseHand finger : direction of Electric currentForefinger : Magnetic force lines


Left Hand Fleming Rule

Like shown to drawing, when coil packed into a magnetic field, current flows with opposite orientation to left side and right, and magnetic force yielded based on left hand principle Fleming, so that coil creates impulse to turn around, because this revolution takes place continuous, hence required by commutator and brush.


Base Work

Division which towards conductor cord north pole and which towards antartic receives force from vertical direction at the oposite so that rotary conductor cord. This called as revolution principle of motor.

Electric Generator Concept


Function of electromagnetic induction and

induction of electromotive

Showing above drawing a magnet is moved quickly in a coil.

If magnet moved like that in coil, strain will be yielded and lamp will blaze. On the

contrary if permanent magnet in place of hence lamp will die.


A phenomenon so-called right hand law happened between magnetic force lines directions, conductor residing in depth moved and direction of induction electromotive force ( direction of electric current ).

Like shown to drawing, if electrical hand finger is bended [by] hence forefinger will show direction of magnetic force lines, thumb shows direction of conductor impulse and hand finger shows direction of induction electromotive force.

Right Hand Rule


Level of electromotive force changes is proportional with elements following:

Magnetic force strength Conductor length ( magnetic induction increases if length to increase) Speed of rotary conductor

Electromotive force


Rectification of Electromotive force

To yield continuous electromotive force, conductor must continuously protected from magnetic flux.

This thing can be reached by the way of making rotary conductor in magnetic field or with magnet and conductor in a state of keeping quiet in place.


Rectification of Electromotive force

An alternating current generator usually applied to yield energy. When rotary coil at a speed of permanent in magnetic field, electromotive force at fickle coil.

Electromotive force yielded in this way is called as alternating current electromotive force. If this electricity applied as it is ( alternating current ) hence called as alternating current generator.


Generator

When rotary power wheel, magnetic flux in peripatetic stator with impulse repeatedly, so that strain AC induceed in lighting coil or charging coil.

Direct alternating current applied for equipments using source of electricity AC like headlight. While to filling battery, alternating current experiences concurrent by diode before doing impregnation.


Fluid Pump Concept


Definition

Pump is one of functioning engine type to remove fluid from a place to place wanted.

The fluid the example is water, oil or lubricating oil, and other fluid of which is compress not able to.

How To Work

Pump shaft will rotate if the rotary actuator.

Because rotary pump shaft of impeller with rotary impeller blades

The fluid in it will rotate so that accentual and the speed rising and thrown from middle pumped to passage which is in the form of volut or spiral then out through nozzle


How To Work

Function of pump impeller is change mechanical energy that is revolution of impeller becomes fluid dissociation energy of diatomic ( fluid).

Compresor Concept


Compressor is Compress device or air compression equally compressor is compressed air producer.

Because compression process, air has higher level dividing valve

Compared to area air pressure (1 atm).

Refrigeration Concept


Definition

Refrigeration engine in general applied for air conditioning a room, housing or industry, so that each and everyone is residing in at ruagan will feel balmy.

This device usualy is called as with Air Conditioning


Component

CompressorCompressor is as circulation refrigerant actuator to.

CondenserCondenser functions to throw away calorie from area refrigerant

Expansion valveExpansion valve is functioning device refrigerant expansion to so that its(the dividing valve is downwards.

EvaporatorEvaporator is place where calorie from area is permeated to be used vaporization of refrigerant.


Component


How To work

Refrigerant is in the form of semi liquid

Refrigerant is made cool so that is in the form of liquid

Compressor functions circulation of refrigerant to in system

Change refrigerant from fluid to gas

Refrigerant in evaporator permeates temperature from the air passing it
