I'd like to note that the 10kHz frequency is not the analogue frequency to the 60Hz the motor is driven by. It means that a pulsating current of 10kHz is modulated with 0...around 10 or 100Hz or something. And that's the frequency the motor's speed depends on. :o)
thanks... I am not really an electrician or an elevator technician and I welcome this knowledge...
for this elevator, the door drive is also modulated at triple-phase high frequency power :-)

Nice video by the way, thanks a lot!
