BLD025A无刷电机驱动器
BLD025A brushless motor driver
Product introduction:
BLD025A is suitable for speed regulation of three-phase brushless DC motors with VDC18 ~ 63V DC 25A or less. The design of this product adopts advanced digital signal processor control technology, which has the characteristics of large torque, low noise, small vibration, fast start and stop. At the same time, it has over-voltage, under-voltage, over-current and over-temperature protection functions. Functions such as manual speed adjustment, upper computer analog voltage speed adjustment, start and stop forward and reverse are realized. Simple application and simple operation.

Terminal number Signal type Signal description
ALM output signal Alarm signal output port, normally 5V when the fault occurs, the level is 0V
SPEED Speed signal output port, corresponding to the running speed of the motor, output the corresponding pulse frequency
BRK control signal   Motor fast brake signal port, disconnecting the BRK port from the COM port for fast braking, short circuit closing for normal operation
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.
F / R Motor rotation direction control port, when F / R port and COM port are disconnected, the motor rotates clockwise, and the short circuit closes counterclockwise.
COM Common port (0V reference level)
SV Speed control signal input port, the middle lead-out terminal is connected here when external potentiometer is used for speed control, and both sides are connected to VCC and COM ports respectively
VCC External potentiometer power interface
REF + Hall signal DC Brushless Motor Hall Signal Power Cord
HU HU Brushless DC Hall Signal HU
HV   HV Brushless DC Hall Signal HV
HW HW Brushless DC Hall Signal HW
REF- 接地线 Hall signal ground wire of DC brushless motor
U Motor connection U相 Brushless DC motor U-phase
V V相 Brushless DC motor V phase
W W相 Brushless DC motor W phase
DC- Power connection DC power connected to negative pole
DC +   DC power is connected to the positive electrode (voltage range: 18 ~ 63VDC)
