ESC (Electronic Speed Controller) Selection forWaterproof BLDC Motor

  • The speed of the 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 the 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 a brushless DC motor.

Tips: What is a sensorless BLDC motor?

A sensorless brushless DC motor (sensorless BLDC motor) is quite simplya brushless DC motor without hall effect sensors. Hall effect sensors are sensors that are built into sensored brushless motors which are used to tell the brushless motor controller exactly where the rotor position is.
