Variable voltage speed control of brushless dc motor

General essentially belongs to the servo motor,brushless dc motor made up of synchronous motor and drive,frequency conversion speed regulating motor.Variable voltage speed control of brushless dc

motor is In the true sense of the centrifugal pump brushless dc motor,it consists of stator and rotor,stator consists of core,coil adopts "shun - inverse - direct - reverse..." Winding,the resulting N - S group Fixed magnetic field of the rotor is composed of a cylinder magnet with axis (middle),or is composed of electromagnet and collector ring,the brushless wholesalemotor.blogspot.com dc motor can produce torque,but can't Controls a direction,no matter how to say,this machine is a significant invention.When as a dc generator,the present invention can produce continuous amplitude of the direct current Flow,thus motor fan avoid the use of filter capacitor and the rotor can be permanent magnet,with brushless excitation or brushless excitation.When as a large motor,this electricity to produce self-induction,the need to adopt With protection device.
