What is a motor stator and rotor? What is the role of the stator and rotor?

The general motor consists of two parts: the fixed part is called the stator, the rotating part is called the rotor. In addition there are end caps, fans, enclosures, machine bases, junction boxes and so on.
The role of the stator is to generate a magnetic field and act as a mechanical support for the motor. The stator of the motor is composed of stator core, stator winding and machine base. Stator winding embedded in the stator core, the current generated by the induced electromotive force, to achieve electrical energy conversion. The main role of the base is fixed and supporting the stator core. When the motor is running, the heat generated due to the internal loss is transmitted to the base through the core, and then is emitted to the surrounding air from the base surface. In order to increase the cooling area, the general motor in the outer surface of the base design for the heat sink.
The motor rotor from the rotor core, rotor winding and shaft composition. The rotor core is also used as part of the motor’s magnetic circuit. The role of the rotor winding is induced electromotive force, the electromagnetic torque generated by the current. Shaft is to support the weight of the rotor, torque transmission, the main mechanical output power.
