    ESC (Electronic Speed Controller) Selection for E-Board BLDC Motor

    • The speed of BLDC motor does not exceed the speed of ESC, it can be matched and used.
    • Brushless DC motor speed calculation formula: battery voltage * motor KV value.
      Brushless DC motor stator speed calculation formula: motor KV value * battery voltage * motor pole pairs.
    • The limit speed of V4 series ESC is 60000 ERPM.
      The limit speed of V6 series ESC is 15000 OERPM.
    • If the maximum speed of BLDC motor exceeds the speed of electric speed controller, the ESC can also be matched by reducing the working voltage of motor. But we do not recommend this, because it does not really play the role of brushless DC motor.

    Tips: Outrunner BLDC motor used in electric skateboard.

    The BLDC motor whose rotor rotates with motor housing and spindle is fixed is the outrunner motor. In contrast, the motor whose rotor rotates with motor spindle and the base is fixed is the inrunner motor.

    Generally speaking, outrunner brushless motor has many poles, low speed and high torque. The inner rotor has few poles, high speed and low torque. Usually the rotating part is the part where the magnet is embedded, and the non-rotating part is the coil part.

    In the case of the same weight of rotor, the internal rotation is not as large as the external rotation, so the KV of internal rotation is high and the torque is low, while the external rotation is just the opposite.
    The inner rotor motor has low torque and high speed, and is mostly used in vehicle models (such as cars, boats and helicopters). The outrunner brushless motor has better heat dissipation and is suitable for electric skateboards and other equipment.

    Can a 5000W brushless DC motor drive the compressor unit?
    Could we use your bldc motor to drive the compressor unit?

    BLDC motors can be used on compressor unit, but depending on the specific application environment, such as temperature requirements. Also depends on the actual use of the compressor, what are the requirements of the motor parameters, such as torque, speed, current and so on.
