Applications of generators and motors

In this post, we will briefly discuss the different applications of generators and motors.

Applications of generators and motors in cars

Alternator in cars

A car contains an alternator that charges its battery and powers the car’s electric system when its engine is running. Alternators have the great advantage over direct-current generators of not using a commutator, which makes them simpler, lighter, less costly, and more rugged than a DC generator.

Starter motor in cars

A car also contains a DC electric motor, the starter motor, to turn over the engine to start it.
A starter motor consists of the very powerful DC electric motor and starter solenoid that is attached to the motor. A starter motor requires a very high current to crank the engine, that’s why it’s connected to the battery with large cables.

More applications of generators and motor are listed below:

Applications of Generators

  • car alternator
  • bicycle dynamo
  • hybrid electric vehicle (HEV) drive systems
  • aircraft auxiliary power generation
  • wind generators
  • high-speed gas turbine generators

Applications of Motors

  • in electric drills
  • in washing machines
  • in mixers
  • in dentist drills
  • in fans
  • the starter of a car
