Surge voltage of 400 V inverter

It is explained that surge voltage is influenced by the switching speed of the inverter. Therefore, can motor burnout be prevented by lowering the carrier frequency?
Category : 


No. Although the carrier frequency increases or decreases the switching count, the switching speed is the OFF-to-ON speed of the IGBT element of the inverter.
Therefore, lowering the carrier frequency does not change the switching speed and cannot prevent motor burnout.
