BLD050A brushless motor driver
Product introduction:
BLD050A is suitable for speed regulation of three-phase brushless DC motors with VDC 18 ~ 60V DC 50A 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
SPEED output signal Speed signal output port, corresponding to the motor running speed, output corresponding pulse frequency
ALARM Alarm signal output port, normally 5V, 0V when fault occurs
SV control signal External speed control input port. When the external potentiometer adjusts speed, the middle lead wire is connected here, and the two sides are connected to VCC and COM ports
COM Public port (low level )
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.
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
