Strict current limit and torque control.High-speed low-loss synchronous rectification PWM modulation.Powerful and intelligent microprocessor.Specially designed for electric vehicles like electric motorcycles and scooters.The motor with the least Io will have the least iron losses between two motors with equal internal resistance. Use this to better understand the performance capability of your motor.

This motor constant is fairly easy to obtain as it is a direct measurement that can be performed very safely.

The reason for 10v is the motors no load current does not tend to change significantly when you get outside this value. This is important to note as the current measured does tend to vary as voltage is above or below this value. Typically, motor manufactures are testing the motors at 10v. Manufactures select a voltage for the motor to be tested at. The no load current is measured in Amps and denoted “Io.” The key point here is that the current is measured at a specific voltage. The no load current of a brushless motor is defined as the current the motor draws, with no load applied, at a specific voltage. What is the Brushless Motor No Load Current
