jackpot slot app Fractional slot tooth windings cause additional space harmonics in the air gap which cause additional torque ripple and rotor losses

If the number of slotspolephase is fractional and superior to 1, the winding is called fractional-slot winding If the number of slotspolephase is

fractional slot winding The proposed design offers the minimum total harmonics distortion in the magnetomotive force produced by the winding whereas winding factor of the working

Abstract PM machines in which slot number and pole number combination differs by one have to be configured with asymmetric winding pattern in order to maximize
