Abstract
The rotor windings of this synchronous motor are located in rectangular slots (5) between the ples (2). The windings are also in a rectangular form and parallel to the walls of the slot. They are separated from each other by a comb of insulating material (9) at the top and bottom of the slot. The windings are held in place by a wedge-piece (10) between the poles. In this way, air-channels between the windings are formed that can be ventilated in an axial direction along the rotor thus giving improved heat removal from the coils.
