Introduction to Electric Motor

Electric motor based on the principle of rotation for the left hand rule Fleming, when a wire placed in a magnetic field, if the wire through the current, the wire will cut the wires generate magnetic field lines move. Current into the coil produces a magnetic field, the use of current magnetic effect, the solenoid magnet at a fixed continuously rotating device that can convert electrical energy to mechanical energy. And a permanent magnet or another magnetic field generated by the coils interact to generate power. The principle of the DC electric motor the stator does not move, the force generated by interaction of the rotor according to the direction. AC electric motor is an alternating electric current through the stator windings, a rotating magnetic field, with the rotating magnetic field to attract the rotor rotates.
Many different types of electric motor, the basic structure is concerned, its main components – stator and rotor. The stator stationary in space, and the rotor can rotate around the axis, the bearing support. Between the stator and rotor will have a certain air gap, to ensure that the rotor can rotate freely.
Electric motor uses many, ranging from heavy industry, small to small toys has its traces. In different circumstances would choose different types of electric motor.
