ESC (Electronic Speed Controller) Selection for Waterproof 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: Can brushless dc motor work underwater?
Most BLDC motors are not waterproof as they are not required to operate in an environment. The waterproof material also limits the overall performance of the motor while increasing the cost. These costs are usually only valuable for specific applications, such as electric surfboards, submersible propellers, and other applications where the motor may come into contact with liquids.
Brushless.com Waterproof brushless DC motors work underwater. This is a common industry standard named after waterproofing. This is not a modified standard motor, but a true waterproof motor that will work well in deep water environments. Motors are equipped with redundant shaft seals, O-rings, sealed cable feed-throughs, pressure equalization and other waterproofing features. These design features keep the waterproof BLDC motor from failing even after prolonged exposure to water.
