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 applications are outrunner BLDC motors commonly used in?
A: Outrunner motors are commonly used in applications that require high torque at relatively low speeds, such as drones, RC aircraft, electric skateboards, e-bikes, gimbals, and robotics. These motors are BLDC motors, offering a lightweight design, smooth rotation, and efficient direct-drive performance, making them also suitable for industrial automation equipment and hobby projects where compact size and reliable torque output are important.
