Abstract
The influence of the number of rotor slots on the performance - electromagnetic torque production, torque ripple, rotor losses and power factor - of an axial-flux (AF) aluminium-cage solid-rotor core induction motor is studied. The number of stator slots in the study was 36 and the number of the rotor slots was varied between 24 and 32. The width and depth of the rotor slots were kept at initial values. The maximum torque at a certain slip value was achieved at the number of 25 rotor slots. The rotor losses as a function of the number of rotor slots seem to decrease almost linearly when the number of the rotor slots was varied between 24 and 31.
