BLD015A brushless motor driver
Product introduction:
BLD015A brushless motor driver is a high performance brushless driver product developed for medium and low voltage DC brushless motors. DC brushless motor driver is suitable for speed regulation of three-phase brushless DC motors with 12 ~ 58VDC and 300W power. BLD015A has a variety of speed adjustment modes to choose from, which can provide internal potentiometer speed adjustment, external potentiometer speed adjustment, external analog voltage speed adjustment, host computer (programmable controller PLC, microcontroller, etc.), pulse width speed adjustment and Over-voltage, under-voltage, over-current and Hall illegal protection functions.

DC + Current connection DC power is connected to the positive electrode (voltage range: 12 ~ 58VDC)
DC- DC power connected to negative pole
W Motor connection Brushless DC motor W phase
V Brushless DC motor V phase
U Brushless DC motor U-phase
REF + Hall signal DC Brushless Motor Hall Signal Power Cord
HW HW Brushless DC Hall Signal HW
HV HV Brushless DC Hall Signal HV
HU HU Brushless DC Hall Signal HU
REF- Hall signal ground wire of DC brushless motor
SV control signal Speed control signal input port, the middle lead-out terminal is connected here when external potentiometer speed control, both sides are connected to REF + and COM port
COM Common port (0V reference level )
F / R Motor rotation direction control port, when F / R port and COM port are disconnected, the motor rotates clockwise, and short circuit closes counterclockwise
EN Stop signal control port, the EN port and COM port are disconnected for the motor to stop slowly, and the short circuit is closed for normal operation.
BRK Motor fast brake signal port, disconnecting the BRK port from the COM port for fast braking, short circuit closing for normal operation
SPEED output signal Speed signal output port, corresponding to the running speed of the motor, and output the corresponding pulse frequency
ALM Alarm signal output port, normally 5V when the fault occurs, the level is 0V
