Rotor Losses

Purpose The purpose of this paper is to present a synthesis of the analysis and modeling of the rotor losses in high speed permanent magnets motors. Design/methodology/approach Three types of losses are as a result of eddy currents in the conductive parts of the rotor. The analysis includes their characterization and the setup of a numerical model using finite element method. The adopted methodology is based on the separation of the losses which allows a better understanding of the physical phenomena. Each type of losses will be modeled and computed separately. Findings It is possible to make a precise estimate of the different losses in the rotor while keeping a relatively short computing time. Research limitations/implications The analysis is applied on a high-speed permanent magnet motor for avionic application. The model is validated with the commercial finite element model (FEM) software Flux2D. Originality/value The developed model allows an important save in terms of CPU-time compared to commercial FEM software while staying accurate. The separation of each losses and their sources is important for motor engineers and was requested for them to improve the designs more easily.

The influence of current harmonics on high-speed permanent magnet motor is analyzed in this paper. The several aspects influence of current harmonics are analyzed in detail such as on the stator core losses, copper losses, as well as additional losses, the rotor losses, the electromagnetic torque etc. The necessity of suppressing current harmonics for high-speed motor stable and reliable running and the key issues of high-speed motor control system stable operation is stated.
