bldc motor controller is the leading voltage AC motor running, widely used in electric fans, refrigerators, washing machines, air conditioners, hair dryer, vacuum cleaner, range hood, dishwasher, electric sewing machines (to be found food processing machines and other household appliances and various electric tools, small electromechanical devices.
bldc motor driver is divided into induction motors and AC commutator motor. Divided into single-phase induction motor asynchronous motor, AC and DC motors and repulsion motor.
bldc motor driver basic principles:
(1) When access to three-phase AC induction motor three-phase power, three-phase stator windings generate current flow through the three-phase symmetrical three-phase magnetomotive force (the stator rotating magnetic momentum) and produce a rotating magnetic field.
(2) The conductor of the rotating magnetic field and the rotor has a relatively cutting exercise, according to the principle of electromagnetic induction, EMF and rotor conductors induced current.
(3) According to the law of the electromagnetic force, the current-carrying conductor in a magnetic field in the rotor by the electromagnetic force, the formation of the electromagnetic torque, driving the rotor rotation when the motor shaft with a mechanical load, then out the output mechanical energy.
