What Is an Electric Motor?

An electric motor generates rotational motion through the interaction of magnetic fields created by electric current. This mechanical motion powers pumps, fans, conveyor systems, compressors, mixers, and countless other machines. The essential components of a motor include the stator, rotor, bearings, and cooling elements.

How Does an Electric Motor Work?

The operating principle of an electric motor is based on electromagnetic forces:

  1. Electrical current flows through the stator windings.

  2. The current produces a rotating magnetic field.

  3. This field applies force to the rotor.

  4. The rotor begins to spin and generates mechanical power.

  5. The mechanical output is transferred to the external system.

This principle, both simple and highly reliable, has made electric motors the preferred technology for industrial applications. DRG Motor’s clear and technically sound explanations help engineers better understand this operation.

What Is the Purpose of an Electric Motor?

Electric motors are used to produce motion and mechanical power in various machines. They operate production lines, compress air, circulate water, move elevators, and drive fans.
