Just a quicky for Jazz - I know where you're coming from with the plate on the spindle, but googling the part number throws up bugger all info on aliexpress, but it does suggest that it can be wired star or delta, and a 6-pin connector on the spindle brings out each winding separately, and that the coil voltage is 220/380.

OP - Might be worth posting a photo of the electrical connector on the spindle.
