ESC (Electronic Speed Controller) Selection for Waterproof BLDC Motor
- The speed of the BLDC motor does not exceed the speed of ESC, it can be matched and used.
- Brushless DC motor speed calculation formula: battery voltage * motor KV value.
Brushless DC motor stator speed calculation formula: motor KV value * battery voltage * motor pole pairs.
- The limit speed of V4 series ESC is 60000 ERPM.
The limit speed of V6 series ESC is 15000 OERPM.
- If the maximum speed of BLDC motor exceeds the speed of the electric speed controller, the ESC can also be matched by reducing the working voltage of motor. But we do not recommend this, because it does not really play the role of a brushless DC motor.

Tips: How to test the airtightness and waterproofness of the outrunner bldc motor's housing?
The key to the air-tightness and waterproof detection of the motor shell is the auxiliary fixture. Due to the particularity of the motor shell, it is necessary to customize the corresponding mold for the air-tightness and waterproof detection of the motor shell. Put the product into the mold, and the upper mold is down Press and fix the product and set up a test port to test by inflation. The test pressure is 250KPA, the inflation time is 10 seconds, the voltage stabilization time is 10 seconds, the test time is 5 seconds, and the leakage value is 0.05KPa. The OK/NG products can be quickly detected by using the sensor in the motor housing air tightness detection device, and the motor housing air tightness and waterproof detection equipment use compressed air, which can realize fast motor housing air tightness and waterproof detection.
