Abstract
The authors analyze the suitability of a synchronous motor as compared to an induction motor by considering the machine torque-density and the inverter power size needed for a given constant-power speed range. It is shown that an axially laminated reluctance motor gives more torque-density than the induction motor, but requires nearly the same inverter size. The addition of a proper quantity of permanent magnets allows the inverter size to be greatly reduced. A comprehensive discussion is made on this subject, with the aim of pointing out a design solution optimal for the whole drive.Keywords
