What should you pay attention to when using a brushless DC motor controller?
  • First of all, our motor drawings will have the definition of the motor’s outlet wires. There will be eight wires if it is an inductive DC brushless motor with a Hall sensor. We need to follow the driver manual’s wiring instructions for three phase wires (U V W) and five Hall wires (5V Hu Hv Hw 0V).
    Correctly connect the lead between the motor and the driver. Wrong wiring will cause the motor to operate abnormally.
  • The positive and negative poles of the current cannot be connected reversely. DC+ is the positive pole, and DC- is the negative pole. Follow the text instructions on the driver.
  • Regarding the rated voltage and rated current of the motor driver, as well as the rated voltage and rated current of the motor, there may sometimes be misunderstandings. Generally, brushless dc motor controllers have an input voltage range that the driver itself can accept, such as 15V to 50V.
  • However, the voltage range of our switching power supply or lithium battery that supplies power to the driver is match the rated voltage of the brushless DC motor. Not the voltage range that the motor driver can accept. The normal power supply of the driver is ±10% of the rated voltage of the brushless motor.
  • If the voltage is too high, too much voltage will cause the driver to give an over-voltage alarm, and too low a voltage will cause the driver to provide an under-voltage warning. The most common voltage for brushless DC motors is 12v, 24v, 36v, 48v, 72v, 96v, and 310v (when the driver power supply voltage is AC220V).
  • Drivers of different sizes also have different rated current values that can withstand. When we choose a brushless DC motor driver, we need to ensure that the driver rated current allowed by the drive is 30% to 50% higher than the rated current of motor. Different requirements for overload torque are determined according to different applications.
