ABSTRACT:
An arrangement for mounting a stator winding in a stator of an elevator machine motor, where the stator may include a stator frame with a plurality of stator teeth and one or more slots between given stator teeth. The arrangement may include a winding frame configured to support the stator winding so that the winding is fitted in the slots and is adapted to be secured by fastening elements provided in the slots. The winding frame may include a frame bottom in contact with one or more side faces of given slots. The arrangement may include one or more flexible locking elements projecting from the frame bottom and adapted to be fit into holes provided in the slots. The locking elements may be inserted into corresponding holes to lock the winding frame and stator winding to the stator frame, as the winding frame is being pushed into the slots.
