For a 48-slot winding the full-pitch is 12 slots for four poles, and 8 slots for six poles. Single-layer windings can be developed (not exclusively)3 where 4-pole and 6-pole windings have opposite directions of rotation. The 9- slot shifting represents an average between 8 slots (the phase shift for...

CN102983653A - Single-layer short isometric winding of 48-slot 4-pole ... The invention relates to a single-layer short isometric winding of a 48-slot 4-pole three-phase asynchronous motor, belongs to the field of the structural design of motors, and aims at providing the single-layer short isometric winding which is capable of improving motor efficiency and saving wires, and is convenient to wind and simple in embedding the wires. COIL PITCH IN AN AC ARMATURE WINDING FULL PITCH WINDING - Davidson Sales coil starting in slot number one (1). Example: the throw could be 1 to 9 meaning that one side of the coil is inserted in slot #1, and the other side in slot #9. 2. Coil Span: The number of core slots spanned by the sides of the coil. In the above example, the span would be 8 slots (9 – 1). 3. Slots Per Pole: The number of slots in the armature core divided by the number of poles constituting the field. Example: In a 4 pole generator having a 48 slot armature core, the number of slots per ... Wave Winding | Electrical4U

Armature windings, along with the ... Two slot winding In this type of winding the slots per pole ... Two slot winding : In this type of winding, the slots per pole per phase will be equal to two. Example 3.12 : For a 3 phase, 48 slots, and 8 pole machine Slots per pole per phase = = 2. 3.14 SINGLE LAYER WINDING : In this type of winding, as shown in Fig. 3.12 (a), each slot contains only one coil side. ELECTRICAL MACHINES II - uotechnology.edu.iq b. Fractional-slot winding can be used c. Chorded-winding is possible d. Lower-leakage reactance and therefore , better performance of the machine e. Better emf waveform in case of generators. 6. Pole – pitch. A pole pitch is defined as the peripheral distance between identical points on two adjacent poles. Pole pitch is always equal to 180 o 7. Motor Rewiring - practicalmachinist.com * is not an integral factor of 36. Unless a slot is partialy wound for each pole an eight pole motor would require a 24 or 48 slot stator. As stated above, 36=3*3*2*2. 48=3*2*2*2*2 I think that 36 slot stators could be used at least for 2,4 and 6 pole motors. I would expect that 48 Slots would make at least 2,4 and 8 pole motors.
