Due to the simplicity of modulator and control, parametrization is straightforward. The algorithms are implemented on an industrial drive controller. Measurement results show the advantages compared to standard PWM schemes using asynchronous space vector modulation (SVPWM).

Therefore a way to reduce rotor losses by using shielding cylinders is proposed and the effects of these measure are discussed according to the main causes of the rotor losses, which are current harmonics and winding harmonics. The loss minimisation will be demonstrated a for a specific high-speed motor design.

The additional losses in the rotor caused by harmonics are particularly critical, as they act in the center of the machine. This paper shows an approach to reach small additional losses without a filter between inverter and machine. Y1 - 2022 SN - 978-9-0758-1539-9 SP - 1 EP - 10 PB - IEEE ER -
