    ESC (Electronic Speed Controller) Selection for Waterproof 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: How to Effectively Waterproof Brushless Motor?

    Brushless motors are waterproof motors that work up to 30 feet below the ocean floor. This is a common industry standard named after "waterproof", not a modified standard motor, but a true waterproof motor, and they work well in deep water environments. Each strategy provides a different level of liquid protection when exploring waterproofing solutions. Many waterproofing methods will restrict air flow to the motor, which will negatively affect the high power output of the brushless motor. Common and effective motor waterproof methods are as follows: Covering the motor with a special housing is one of the common ways to prevent water damage. Use a waterproof shaft seal. It protects the moving parts of the motor, especially the shaft and bearings, and the waterproof shaft seal creates an enclosed area for the inner workings of the motor.
