ESC (Electronic Speed Controller) Selection for Waterproof BLDC Motor
- A BLDC motor can be used with an ESC as long as its speed does not exceed the ESC’s limit.
- BLDC motor speed = Battery Voltage × KV value;
Stator speed = Battery Voltage × KV value × Pole Pairs.
- The maximum speed limit of the V4 series ESC is 60,000 ERPM.
The maximum speed limit of the V6 series ESC is 150,000 ERPM.
- If a BLDC motor’s maximum speed surpasses the ESC’s limit, it is possible to match them by lowering the motor’s operating voltage. However, this is not recommended, as it prevents the motor from functioning as a true brushless DC motor.

Applications
Q: What is an outrunner BLDC motor?
A: An outrunner brushless DC (BLDC) motor is a type of BLDC motor where the outer casing and the magnets attached to it rotate around a stationary inner component called the stator, which contains the coils. This design provides a high-torque, low-speed output, making it suitable for applications like drones, electric vehicles, and cordless tools, though it places more demands on the electronic speed controller.
