The use of energized coils (also known as stator windings) to generate a rotating magnetic field and act on the rotor (e.g., squirrel-cage closed aluminum frame) to form a magneto-electric power to rotate torque. It can also be said that: the energized coil is subjected to a force in the magnetic field.
Introduction:
An electric motor is a device that converts electrical energy into mechanical energy. It uses an energized coil (also known as a stator winding) to generate a rotating magnetic field and act on a rotor (such as a squirrel cage closed aluminum frame) to form a magneto-electric power rotating torque. Electric motors are divided into DC motors and AC motors according to the use of different power sources, most of the electric motors in the power system are AC motors, which can be synchronous motors or asynchronous motors (motor stator magnetic field speed and rotor rotational speed does not maintain synchronous speed). The motor consists of a stator and a rotor, and the direction of the force on the energized wire in the magnetic field is related to the direction of the current and the direction of the magnetic inductance (direction of the magnetic field). The working principle of the motor is the role of the magnetic field on the current force, so that the motor rotation.
