    Tips: Why do a brushless DC motors need to be equipped with a BLDC controller?

    The brushless DC motor replaces the mechanical commutator with an electronic commutator. Because of the electronic commutation, the brushless DC motor needs a driver drive circuit. The commutation circuit of a brushless DC motor is composed of two parts: drive and control. The two parts are not easy to separate. In particular, low-power circuits often integrate the two into a single application specific integrated circuit.

    Brushless DC motors do not have brushes and commutators, so if you want to maintain the direction of rotation, you must have an electronic commutator. The electronic commutator is controlled by the driver. At the same time, the brushless motor controller can also control the start and stop of the motor, forward and reverse rotation, speed adjustment, overvoltage, overcurrent and undervoltage protection. So there must be a brushless motor controller, even if the DC brushless motor is directly energized, it will not work.

    Existing reviews of Brushless DC Motor Controller, 12V ~ 30V
    Works excellent on brushless DC motor.
    This BLDC motor controller works great and so smoothly from low to high speed in both directions with excellent low speed control. It is actually a nice little device. Overall I’ am happy with this product. Just bought another.

    Work excellent!
    If you want to run a BLDC motor by variable speed, this controller is going to do it for you. Definitely usable. The most handy brushless test controller! Strong enough to quick test my brushless ebike motors.
