Abstract

A high power density integrated non-overlapping concentrated tooth winding synchronous machine with embedded permanent magnets for a hydraulic motor-pump is designed. Direct liquid cooling with the working fluid itself is implemented. Aspects of immersing the motor into hydraulic oil for cooling purposes are discussed. FEM modelling of PM eddy-current losses and static temperature evaluation are performed.
