ESC (Electronic Speed Controller) Selection for Waterproof BLDC Motor

• The speed of 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 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 brushless DC motor.

Tips: What is Skin Effect？

Skin effect is a phenomenon that the current distribution in a conductor is not uniform when there is an alternating or alternating electromagnetic field in the conductor. As the distance from the conductor surface gradually increases, the current density in the conductor decreases exponentially, that is, the current in the conductor will be concentrated on the surface of the conductor.

From the transverse section perpendicular to the direction of the current, the current intensity in the center part of the conductor is basically zero, that is, almost no current flows through, and only the part of the edge of the conductor will have current. Simply put, the current is concentrated in the "skin" part of the conductor, so it is called the skin effect. The main reason for this effect is that the changing electromagnetic field creates a vortex electric field inside the conductor, which cancels out the original current.
