* DC motor: Converts electrical energy into mechanical energy.
* DC generator: Converts mechanical energy into electrical energy.
DC motors are used in a wide variety of applications, such as electric vehicles, power tools, and industrial machinery. DC generators are used to generate electricity for a variety of purposes, including power generation, battery charging, and electroplating.
Construction
DC motors and generators are both made up of a stator and a rotor. The stator is the stationary part of the machine, while the rotor is the rotating part. The stator is made up of a series of electromagnets, while the rotor is made up of a series of permanent magnets or electromagnets.
Operation
When a DC motor is connected to a power source, the electromagnets in the stator create a magnetic field. This magnetic field interacts with the magnetic field of the rotor, causing the rotor to rotate. The speed of the rotor is controlled by the strength of the magnetic field and the amount of current flowing through the electromagnets.
When a DC generator is connected to a mechanical power source, the rotor rotates. This rotation causes the magnetic fields of the rotor and the stator to interact, generating a voltage in the electromagnets. The voltage generated by the generator is proportional to the speed of the rotor.
