Connect the wires first, then power on. The BL30V750 sensorless brushless motor driver is a wide-voltage, high-current, high-performance driver developed for Hall-less DC brushless three-phase motors. Before use, please confirm the motor's voltage and power parameters, which must conform to the range specified by this module. It features simple peripheral circuitry, complete functions, easy debugging, high drive efficiency, flexible application, and wide applicability. Motor control can be achieved simply by connecting the motor's three-phase lines (UVW). The module has no reverse power protection; reversing the power supply cause permanent damage (please be very careful)., Manufacturer: Akfldms
