Fig. 1 Winding factor harmonics for 4-pole 3-phase… Windings with the same number of slots/pole/phase $q$ have the same winding factor. Their winding layouts consist of the same basic sequence repeated by the number of winding symmetries (or machine periodicity). Example: 10-pole 12-slot single-layer 3-phase winding: $q=\frac{12}... Auto Coil Winding Machine for 2 Poles / 4 Poles and 6 Poles… Power: Electric. Slot Number: 12-48 Slots.Winding tooling: each machine has one set winding tooling and three vertical winding forms. The whole set of tooling can be changed, and it takes about 15min. SW-3A Four- pole in-slot winder

Each 6 or 12 pole winding in 48 slots can be enhanced Each 6 or 12 pole winding in 48 slots can be enhanced during the rewinding ( to higher efficiency) in our own way, regardless of the manufacturer (Siemens, AB... Alternators:Two-Layer Winding | electric equipment For the 4-pole, 24-slot stator machine shown in Fig. 37.12, the pole-pitch is 24/4 = 6. For maximum voltage, the coils should be full-pitched. It means that if one side of the coil is in slot No.1, the other side should be in slot No.7, the two slots 1 and 7 being one pole-pitch or 180° (electrical) apart.
