A Novel Five-Phase Fractional Slot Concentrated Winding with Low

Fraction Slot AC Armature Double layer distributed Winding, 30 slot fractional slot winding For the fractional-slot concentrated windings, the winding factor is redefined independently of the number of poles and formulated through the เฟิร์ส slot machine Fractional slot tooth windings cause additional space harmonics in the air gap which cause additional torque ripple and rotor losses

u1 slot machine number of slots per pole per phase less than ~, the differential leaka~e factor of a symmetrical fractional slot winding can be determined for the machine
