Winding three-phase motors with 54 slots is always interesting, sometimes even quite tricky.
This is true even for single-speed and Dahlander windings,
especially in the case of Pole Amplitude Modulation (PAM) windings that are increasingly in use.
How to design a 12/6 and 24/6 pole PAM winding in 54 slots?
All the necessary information is available to you at (link).
