An apparatus and a method for winding turns of coils of pole members (11), in which a pole member (11) comprises at least a flange portion (13b) connected to a body portion (13a) for receiving turns of coils C during winding. The apparatus comprises a conductor dispenser member (50′) for dispensing a conductor W for forming turns of coils C by movement of the conductor dispenser member (50′) with respect to the pole member being wound. The apparatus is also provided with a pole member holder (10) comprising a plurality of seats (15) suitable for receiving a flange portion (13b) of the pole member (11), a plurality of base members (18) of the seats (15) for engaging a first end (13b″) of a pole member (11) with a pushing force and locking means (20) associated with each seat (15) for engaging and referencing a second end (13b′) of the pole members (11) with respect to the conductor dispenser member (50′). The invention also concerns a pole member holder (10) as described in the foregoing.
