Jago Posted August 23, 2011 Report Share Posted August 23, 2011 Hi everyone I have heard many times about the effect of high switching frequencies in motor control, due to the interaction with the machine internal inductance. Does anyone know how to calculate the maximum switching frequency "allowed" for a certain motor drive? Or is it just an "intuitive" decision? Thank you in advance!

marke Posted August 23, 2011 Report Share Posted August 23, 2011 Hello Jago As you increase the switching frequency of the inverter supplying the motor, you increase the switching losses and this usually determines the maximum switching frequency.
