Effects of manufacturing tolerances of permanent magnets in fractional slot permanent magnet synchronous machines

The fractional slot permanent magnet synchronous machines are well-known for their low torque ripple. However, in mass-production machines, not all the permanent magnets are identical due to the manufacturing tolerances and new torque harmonics could appear. In addition, the magnetic field is modifi...
