Minimum Loss Control of Interior Permanent Magnet Traction Motor

This paper presents a new formulation for minimization of copper and iron losses in interior permanent magnet for the purpose of minimum loss control. Motor losses are formulated based on electromagnetic torque to total torque ratio resulting in simplified expression of minimal loss condition which can be easily solved online. The flux weakening method which adjusts electromagnetic to total torque ratio in order to achieve field weakening operation is also proposed.
