Higher PWM switching frequency

Hi!

Is it possible to increase PWM switching frequency in BLDC mode? Ive tried to change it, but if max switching frequency more then 42000 Hz - controller will not start. I think its because wrong timer initialization.

I need it, because I try to use VESC with IronLess motor. And this "ferrous loss free" motors have more effeciency with higher switching frequency. My project is Hybrid RC helicopter, gasoline engine with auxiliary electrodrive.



Dear Benjamin, can we change something for increase PWM? 100kHz is possible?
