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: What is the difference between inrunner and outrunner BLDC motor?

A: An inrunner BLDC motor has the rotor located inside the stator. This design allows it to achieve higher rotational speeds (RPM) but generally produces lower torque, so it often requires a gearbox for applications needing more force. Inrunners are commonly used in RC cars, drones, and other high-speed devices.

An outrunner BLDC motor has the rotor on the outside, spinning around the stationary stator. This configuration generates higher torque at lower RPM, making it ideal for direct-drive applications without a gearbox. Outrunners are widely used in electric skateboards, boats, robotics, and drones where smooth starts and strong torque are important.

In summary, the key difference between BLDC motors lies in rotor placement: an inrunner BLDC motor favors high speed, while an outrunner BLDC motor provides higher torque for direct-drive applications. Choosing the right BLDC motor depends on whether your system prioritizes RPM or torque.
