28 is the drive circuit diagram of the 45V/8A brushless DC motor
. It is a voltage- type open-circuit control. An external adjustable potentiometer is connected to pin 1 to adjust the PWM duty cycle and control the average voltage
supplied to the motor to adjust the speed. The figure shows only one side of the three-phase bridge, with pins 16 (PUC) and 12 (PDC) driving P-channel and N-channel MOSFETs respectively . By removing the two current detection resistors RT and H, the circuit can operate in four-quadrant mode, perform braking control , and obtain average current control .
