Abstract:
A reluctance electric machine comprising:(a) a stator part with stator teeth of magnetically conductive material that are provided with coil windings; (b) a rotor part arranged coaxially with respect to the stator part and located opposite the stator part so as to leave free an air gap therebetween, the rotor part having a number of discrete poles of magnetically conductive material that project in the direction towards the stator part; (c) annular enclosure mounted on the stator part with two legs of said enclosure disposed on sides of the stator teeth forming channels between the legs and the stator teeth for channelizing coolant flow at least for partial sections of the coil windings of the stator part; (d) a sealing layer on the stator part facing the air gap and extending between the legs of the annular enclosure, the sealing layer comprising a first layer for fulfilling the sealing function and a second layer for taking up the forces acting on the sealing layer; and (e) a liquid cooling medium for flow in the channel.
