Hi, mc5w:
It can be done with 12 slots for 8 pole 3 phase( there are also 8 poles in the rotor). Fractional slot has to be used, i.e., one slot contains conductors from different windings (e.g. phase A and phase B).
It is the winder who told me it is impossible to get a balanced 2 phase winding.
Thanks, ScottyUK, but it needs to rewind to a two phase motor so that we can test a new idea.
I thought to use Phase A as D winding and phase B and C in series to form Q winding. However, there might be 3rd harmonic in phase A, which is not desired.
I am still thinking.

Hi, all:
Just wondering if anyone can help me out.
I need to rewind a 3 phase PM AC motor to 2 phase motor. It has permanent magnet on the rotor. There are 12 slots and 8 poles in stator winding.
Is it possible to build a balance 2 phase winding in this case? If not, how can I build a more...
