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 are the advantages of an outrunner BLDC motor compared to an inrunner BLDC motor?

A: A BLDC motor designed as an outrunner has its rotor on the outside, which allows it to generate higher torque at lower speeds without the need for a gearbox, making it more efficient for applications like drones, e-bikes, and robotics. It typically has better cooling because the rotating outer shell dissipates heat more effectively. In contrast, inrunner motors spin faster with lower torque, often requiring gear reduction for similar performance, so outrunners are preferred when direct-drive, high-torque, and smooth low-speed operation are important.
