US3673477A - Pole-changing, three-phase alternating
FIG. 1B shows the slot-vector diagrams for each of the three phases for the four-pole winding of FIG. 1A on a six-pole basis, the slot angle for 6 poles in 18 slots being 60. The phase sequence is A B C for both four-poles and six-poles. In FIG. 1B the coils marked with a circle round the slot number are reversed to give a balanced six-pole ... The armature of a 4-pole, lap-wound machine has 48 slots ... The armature of a 4-pole, lap-wound machine has 48 slots. There are 10 conductors per slot. The axial length of the armature is 10.8 cm, and its diameter is 25 cm. The pole arc is 15 cm and the flux density per pole is 1.2 T. CHAPTER 4 DESIGN OF INTEGRAL SLOT AND FRACTIONAL SLOT ... Parameters 48 slots, 16 poles 60 slots, 16 poles Pole pitch, mm 14.92 14.92 Magnet width, mm 11 11 Slot Skew angle in deg 7.5 3 Tooth width, mm 3 2.4 Back iron thickness, mm 6 4.8 The 48 slots stator has integral slots per pole and 60 slots stator has fractional slots per pole and these two armature windings for quadruplex 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.

200 horsepower, 2-pole rewind, span question - Electric ... 2/ The coil grouping for a 48-slot, 2-pole, double-layer winding is 6 groups of 8. To cut down the coil overhang of a conventional concentric winding, the motor manufacturer employs 2 series-connected concentric groups of 4. These 2 groups are separated by (4 x 7.5) or 30 electrical degrees. Internal Connection Diagrams for Three-Phase Electric Motors ...
