The Parts of an Electric Motor

Parts of an Electric MotorElectric motors operate very differently from internal combustion engines, like those in most vehicles on the road. Electric motors convert electrical energy into mechanical energy to produce power. They operate using magnets and winding currents to generate force, and they have several intricate parts to do so. These are the main parts of an electric motor, some of which may need service or repair on occasion.


The stationary part of an electric motor is the stator. It usually contains windings or permanent magnets. The stator is made of thin metal linings called laminations, which reduce energy losses that would occur if a solid core was used.


The main moving part of an electric motor is the rotor which turns a shaft to deliver force to whichever unit is being powered. The rotor interacts with the stator through conductors that carry currents and generate the power to turn the shaft.

Air Gap

Between the rotor and stator is the air gap, which needs to be a specific distance in order to ensure the magnetic fields properly interact and produce the correct amount of power.


Windings are the wires that are rolled into coils and placed around a laminated iron core that helps form magnetic poles when it becomes energized.


This mechanism is used to change the input of some AC and DC machines. This part is rapidly being replaced by new technologies that have been developed in the past few decades.

The parts of an electric motor are delicate and require service in order to work properly. If you need to rebuild an electric motor make sure you have a professional do the work to ensure that it can properly produce power.
