How Does ESC Switching Frequency Affect Drone Motor Core Loss?
For the same drone motor, changing only the ESC PWM switching frequency can affect motor noise, temperature rise, and even efficiency.Why? PWM changes the current waveform in the motor windings, which affects magnetic field variations in the stator core.For high-speed, multi-pole drone motors, these additional high-frequency variations may cause higher core loss. What Is PWM … Read more
