Abstract :
This paper examines the relationship between rotor design and sensorless control and power conversion properties for four industrially relevant interior permanent magnet (IPM) machine configurations: 36 slot 6 pole stator with v bar rotor, 36 slot 6 pole stator with flat bar rotor, 9 slot 6 pole stator with v bar rotor, and 9 slot 6 pole stator with flat bar rotor. The influence of rotor geometric design variables over the range of current densities at the maximum torque per ampere (MTPA) angle were found using a design of experiments methodology and standardized regression coefficients. Tradeoffs between sensorless control and power conversion properties are found using a Monte Carlo methodology. Power conversion and sensorless control properties were found using hybrid static and time stepping finite element simulations.
