The manufacturing principle of the electric motor:
Use the energized coil (that is, the stator winding) to generate a rotating magnetic field and act on the rotor (such as a squirrel-cage closed aluminum frame) to form a magneto-electric rotating torque . It can also be said that the energized coil is acted upon by 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 (that is, the stator winding) to generate a rotating magnetic field and acts on the rotor (such as a squirrel-cage closed aluminum frame) to form a magneto-electric rotating torque. Motors are divided into DC motors and AC motors according to different power sources. Most of the motors in the power system are AC motors, which can be synchronous motors or asynchronous motors (the stator magnetic field speed of the motor does not maintain the same speed as the rotor rotation speed). The electric motor is mainly composed of a stator and a rotor. The direction of the energized wire's force movement in the magnetic field is related to the direction of the current and the direction of the magnetic field lines (magnetic field direction). The working principle of the motor is the force exerted by the magnetic field on the current, causing the motor to rotate.
