Sizing parameters of interior permanent magnet synchronous motor based on torque-speed characteristics

Abstract

Abstract This paper presents a sizing algorithm for an interior permanent magnet synchronous motor based on its torque-speed characteristic and how these characteristic shifts because of changing motor’s parameters. This knowledge must be helpful in designing motor control systems, where there is no need for a precise model. Also, the proposed method is useful for rapid prototyping based on the existing motor model. The methodology for calculating the torque-speed characteristics is given. The resulting calculated graphs are given. PMSM motor control parameters are designed based on the reference model and verified in MATLAB/Simulink software package. Simulation results are given.
