Based on the principle of rotation of the motor for the Fleming left hand rule, when a wire placed in a magnetic field, if the current through the wire, the wire will cut the wires generate the magnetic field lines move. Current into the coil creates a magnetic field using the current magnetic effect, the solenoid magnet at a fixed continuously rotating device that can convert electrical energy into mechanical energy. And a permanent magnet or by another group of the magnetic field generated by the coil to generate power bldc motor interaction principle is the stator does not move, the force generated by interaction of the rotor according to the direction of movement. bldc motor controller is on the alternating current through the stator windings, a rotating magnetic field, rotating magnetic field attracts the rotor rotates bldc motor with the basic structure include “armature”, “field magnet,” “slip ring”, “brush” . Armature: You can rotate around the axis of the soft iron core wound multi-turn coil. Field magnet: the strong magnetic field of permanent magnet or an electromagnet. Collector ring: coil about two to two semi-circular termination of slip ring, with the coil rotation for changing the current direction of the change to the device. Each half-circle rotation (180 degrees), the coil current to change direction once. Brushes: carbon usually made of slip ring brush contact with a fixed location to be connected to power.
