 The BLWS23MDA Series is a compact construction that implements a DC Brushless controller and a
DC Brushless motor in one streamline package. With the two parts combined into one casing, the
need to wire up the motor has been eliminated. The DC Brushless controller operates off 24VDC. The
high-speed DC Brushless motor can operate at 4000RPM, can generate up to 70 oz-in of continuous
torque, and deliver as much as 180W, with the BLWS23MDA5 offering. Using hall sensor feedback, the
DC Brushless controller operates in a constant velocity mode. The driver is protected against over
current （cycle-by-cycle）, hall sensor error and under voltage. An external potentiometer （10K） or external
voltage （0-5VDC） can be used to control the speed. For top speed open loop operation, 7VDC must
be applied on the Vspeed input. The direction of the motor can be preset by the direction control input.
A Stop function can be done by grounding the Vspeed input.
