Abstract: H-bridge drive is widely used in DC motor control. By controlling the conduction state of each power component of the H-bridge, the DC motor can be turned and speed controlled. Hollow cup motors have special structure and electromagnetic design, and are widely used in fast response systems. The various control methods of H-bridge were analyzed, combined with the special electrical performance of hollow cup motors. Through experimental comparison determined that the unilateral PWM debugging method was a preferred control strategy for hollow cup motors.
