The working principle of the electric motor

   Electric motor (Electric motor), also known as a motor or motors, is a kind of electrical energy into mechanical energy, mechanical energy and then use the kinetic energy generated is used to drive other devices electrical equipment. Motor type is very diverse, but can be roughly divided into AC motors and DC motors for different occasions.
   Works
   Based on the principle of rotation of the motor for the Fleming's left hand rule, when a conductor placed in a magnetic field, if the current through the wire, the wire will cut the wires from moving magnetic field lines. Current into the coil produces a magnetic field, the magnetic effect of the use of current, the electromagnet in a fixed magnet continuously rotating device that can convert electrical energy into mechanical energy. The permanent magnet or by another group of the magnetic field generated by the coil interaction of the principle of generating power DC motor does not move the stator, the rotor according to the direction of force generated by the interaction movement. The stator winding of the AC motor is on the alternating current through the coil, a rotating magnetic field, a rotating magnetic field to attract the rotor for rotation together with the basic structure of the DC motor including the "armature", "field magnet", "collector ring", "brush."
    Armature: 
    You can rotate around the axis of the soft iron core wound multi-turn coils. Field Magnets: generating a magnetic field of powerful permanent magnets or electromagnets. Collector ring: coil for about two to two semicircular termination collector ring, with the coil turn, lets you change the direction of current inverters. Each half turn (180 degrees), the coil current to change direction again. Brush: usually made ​​of carbon, collector ring brush contacts the fixed position, to be connected to power supply.
