A brushless DC motor has different driving principles from the stepper motor. A bldc brushless motor is controlled by an alternating power supply provided by Hall element positioning. Stepper motor is driven directly by a single pulse voltage, without the need for Hall element positioning, by controlling the number of pulses added to the motor, to accurately position the rotation Angl. HEMM provides customers not only the motors but also provide the corresponding motor drivers to meet customer demand. We are a one-stop solution company.
