Abstract
To predict efficiency of interior permanent magnet synchronous motor (IPMSM) for traction motor and to cope with the risk of demagnetization in the permanent magnets, accurate iron loss analysis and understanding of the characteristic of the iron loss are very important at motor design stage. In this paper, we present the method to estimate the iron loss for the IPMSM considering the driving conditions such as both field weakening control and maximum torque per ampere control.
