DC Motor -

1.DC motors are direct current motors

2.DC motors are self starting

3.DC motors generally characterize a continual and standard current flow

4.DC motor is the rotating motor that is capable of converting DC energy into mechanical energy (DC motor) or converting mechanical energy into DC energy. When the DC motor is running as a DC motor, it converts electrical energy into mechanical energy; when the DC motor is running as a generator is running, it converts mechanical energy into electrical energy.

5.DC motor is composed of two major components: Stater and rotor.

A) The part of the DC motor that remains stationary during the motor running is called a stater, and the function of a stater is to produce magnetic field.

B) The part of the DC motor that runs with the motor is called a rotor, and its main role is to produce electromagnetic torque and induced electromotive force, and it is the DC motor hub for energy conversion, which is why it is also called the armature.

AC motor

1.AC motors are alternating current motors.

2.AC motors require effective starting equipment.

3.AC motors are used in variant situations irrespective of the quality of the current flow.

4.AC motor is used to implement the AC power and mechanical energy conversion. Due to the great development AC power systems, AC motors has become the most commonly used motors.

5.Compared with DC motors, there is no commutator and the structure is simple and strong that is easy to manufacture, as a result, high-speed, high voltage, high current, high-capacity motors can be produced easily. Learn about AC servo motors.
