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: Why does electric skateboard brushless motor get hot?
First, use a non-contact infrared thermometer or the temperature measurement gear of multimeter (a multimeter with temperature measurement). Measure the temperature of motor end cover. When it exceeds the ambient temperature by more than 25°C, it indicates that the temperature rise of electric skateboard brushless motor has exceeded the normal range. Generally, the temperature rise of a motor should be below 20°C.
The direct cause of electric skateboard BLDC motor heating is excessive current. The relationship between motor current I, motor input electromotive force E1, motor rotation induced electromotive force (also called back electromotive force) E2, and motor coil resistance R is: I = (E1-E2) ÷ R
I increase, indicating that R becomes smaller or E2 is reduced. The decrease of R is generally caused by a short circuit or an open circuit of the coil. The reduction of E2 is generally caused by the short circuit or open circuit of the coil.
In the maintenance practice of electric skateboard brushless motor, the method to deal with the heating failure is generally to replace the motor.
