Integral-Slot Versus Fractional-Slot Concentrated-Winding Abstract: In slotted axial-flux permanent-magnet (PM) (AFPM) machines, two possible concentrated-winding arrangements can be used: integral slot and fractional slot. Integral-slot concentrated windings (ISCWs) have a number of slots/pole/phase equal to one and have long been a preferred choice with machine designers due to their simple layout. Motor winding - The Electrical Portal Jul 16, 2015 · If number of slots/pole/phase is a integer value then it is integral slot winding. 2. Fractional slots winding . If number of slots/pole/phase is not a integer value then it is fractional slot winding. Advantage fractional slots winding . The fractional slots winding make it possible to reduce the no of slot in motor and that’s why to reduce the size and price of motor. Integral-Slot Versus Fractional-Slot Concentrated-Winding

If spp is not an integral number, this type of winding is called fractional slot winding. The classic de nition of concentrated winding is a winding having one number of slot/phase/poles. However, the recent de nition of concentrated winding is a winding concentrated around one tooth [11]. The attractive advantages of this type of winding are ...
