Modeling and Comparison of Machine and Converter Losses for PWM and PAM in High-Speed Drives
In this paper, models are introduced for calculating the rotor, copper, and core losses of an electrical machine as well as inverter losses, taking the modulation type into account. These models are developed by considering two typical high-speed permanent-magnet synchronous motor topologies (slotted and slotless machines) driven by pulse-amplitude modulation (PAM) and pulsewidth modulation (PWM) converters.
