We developed a high speed induction motor, which has a high intensity rotor with a solid core and copper conductor. This paper describes the electrical characteristics of the high speed induction motor by comparing the experimental and analysis results. Then, we classify the losses into no-load iron loss and stray load loss. Based on the results, we reveal that the iron loss accounts for 74% of the total loss, the inverter harmonics have a small effect on the iron loss, and the harmonic factor of alternating current losses in the primary winding have an influence on the performance of the high speed motor.
