Abstract :
This paper investigates loss minimization in high-speed, low-power Permanent Magnet Synchronous Machines (PMSMs) with tooth-coil windings (TC-PMSMs). The influence of the main geometric parameters on the loss distribution is studied. Stator core and winding losses as well as rotor sleeve and permanent magnet (PM) losses are evaluated. The effect of the magnetic wedges on the loss distribution is examined. The machine working temperature and related PM demagnetization risks at the rated working point are presented for two- and three-phase short-circuits. The total losses of the designed PMSM are evaluated and a minimum total loss value is obtained.
