1, DC brushless motor than the speed of the stepper motor is higher.
    2, DC brushless motor and stepper motor drive principle is different, DC brushless motor is by the Hall element positioning to provide alternating power supply control rotation. The stepper motor is directly driven by a single pulse voltage, and does not require Hall element positioning. The rotation Angle can be precisely positioned by controlling the number of pulses added to the motor.
    3, based on the principle of the drive is not the same, so the general DC brushless motor is used for control accuracy requirements are not high. Stepper motors are used in places where the control accuracy is relatively high.
