  • 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: Advantages of a 140KV sensorless brushless dc motor,

Sensorless brushless motors do not perform well at low speed, their performance at high speed is excellent. It is so good that most ESC manufacturers rely on sensorless synchronization of a sensored motor at high speed. At high speed, most ESCs will alter the timing for the sequence of power pulses that are sent to the motor's windings. In turn, improving efficiency and performance.

Sensorless motors also are lighter in weight, less complicated, and less prone to failure. It is quite easy to damage the thin wire loom that sends all the data from the sensored motor to the ESC.
