摘要： A brushless DC motor control circuit for efficiently controlling motor speed is described. A digital circuit for providing centered pulse turn-on during that period when the specific winding is capable of providing torque for the desired direction of rotation to the rotor is described. Each phase has its own timing circuit including an initial delay-time interval and an on-time interval. These time intervals are set to obtain desired motor speed and efficient motor operation.
