Tips: What are the functions of brushless DC motor controllers?
The brushless DC motor controller can perform simple variable speed control. All important currents are determined by a single external resistor. The motor start and stop can be completed by the power supply of the circuit. The start timing sequence can be completed by two capacitors. The control function can be operated independently, and the peripheral circuit is simple and adopts the new back-EMF commutation technology, which can provide the smallest jitter-free torque and can carry out the most efficient control. It has a commutation PLC, which can effectively suppress the PWM spike noise signal.
Brushless DC motor controller is used for 50W to 750W 3 phase BLDC motor, worm gear motor or planetary gear motor to perform speed control, power supply range from 18V to 52V DC, typical power is 48V DC.
