This paper describes a large number of experiments comparing audible noise, losses and efficiency of different induction motors supplied by an IGBT inverter. The influence of the switching frequency on the motor behaviour is analysed. As a comparison the motor is also supplied directly from the mains. Furthermore two different motors are compared to study the influence of the rotor cage design on the motor behaviour. It is shown that the choice of the switching frequency has a large influence…
