A high-speed analysis method for 3-phase high frequency voltage input sensorless control of interior permanent magnet synchronous motors (IPMSM) driven by pulse width modulation (PWM) inverters taking magnetic saturation into consideration is proposed. By using finite element method (FEM) analysis, partial differential values of flux-linkage can be calculated directly and precisely in a short time. High-speed analysis of motor voltage equations is realized by interpolating table data of calculated partial differential values and using simplified power device models. The geometric relation of motor magnetic circuit and redundancy of motor current help reduce the number of points in table data. Analyzed results are well fit in with experimental results and the validity of proposed methods is confirmed.
