PPM Winding instead of Two Separate Windings (More Power from the Same Core)

ACW

Two speed (6/4 pole, 54 slots) - two separate windings can be replaced with two speed one winding (PPM) in order to get more power from the same core.

Note that it is not about PAM winding that requires an external Wye connection at one speed.

External wiring is absolutely same as in case of two separate windings ( see the figures below).

New winding is single-layer ( 27 coils in total).

Here you can purchase this new winding diagram with all the relevant parameters (winding factor, symmetry and diff. leakage coefficient for both speeds.

This motor with two separate windings is good candidate for such a redesign:

No change in external wiring:
