Specification

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.

Q: How does an outrunner brushless motor work?

A: An outrunner brushless motor works by having its rotor, which contains the permanent magnets, on the outside, rotating around a fixed internal stator with coils. When the stator coils are energized in a specific sequence by an electronic speed controller, they create a rotating magnetic field that interacts with the rotor magnets, causing the rotor to spin. This design produces high torque at low speeds, making BLDC motors efficient for applications such as drones, electric skateboards, and robotic arms.
