Due to the specific starting and operation, the winding of the motors of refrigerant compressors could be very unusual.
Generally, the winding of these motors is one of the many types of so-called PWS windings.
One of the most elusive 4 pole PWS connections in 36 slots is mixed ( single-double layer) winding with 30 coils and specific patern. It's very likely to be misinterpreted. Also, the value of turns per coil in full and half slot coil is not always as you can expect.
Here you have the opportunity to purchase our document in pdf containing an
internal connection diagram, winding arrangement and simmetry test for the
case in practice, ie 36 slots, 4 pole with winding divided in two parts (2/3 + 1/3).
This winding is mixed ( single-double layer, with 30 coils) for Y connection.
Knowledge of this kind of winding will be at an advantage compared to other rewind shops.
