A numerical analysis of rotor losses in a medium and high speed direct torque controlled permanent magnet synchronous motor(PMSM) is presented. The calculation of stator currents at no load, and at rated torque was performed by using a DSP based emulator, which simulates the performance of a real direct torque controlled PMSM. It is shown that in the medium and high speed direct torque controlled PMSM, the rotor losses were considerably higher when operating at no load compared to rated torque operation at the same rotation speed. Calculated rotor losses are compared to the measured no load losses of the direct torque controlled PMSM at 7500rpm.
