Interior permanent magnet type synchronous motor (IPMSM) is widely used due to the characteristic and the reluctance torque contribute to total output with magnetic torque. It can make the motor have high power density, but also make he motor design and control difficult.
This Paper deals with design and analysis of IPMSM should have high speed limit with constant torque, Firstly, the torque-speed characteristics are calculated according to electric parameters such as current phase angle, back EMF, d-axis and q-axis inductances, ect. And then, the comparison and analysis of the calculated results show which parameters affect the output characteristics. At last, the results of an improved design to widen the operating speed limit considering the essential arameters are presented. The calculated and measured parameters are compared, and it show agreements.
