In this study, we verify the errors in sensorless magnet temperature estimation by using the induced voltage of interior permanent magnet synchronous motor and applying electromagnetic field analysis. The method considered for reducing the errors verified the effect of current and magnet temperature on inductance in the motor. As a result, the estimation errors were reduced from a maximum of 33°C to 0.4°C or less.
