Abstract
A stator arrangement for an electric motor. The stator arrangement including a laminated stator core with stator windings running through stator grooves and forming winding overhangs at each end face of the laminated stator core. The stator arrangement also includes an interconnection unit having a switching disk covering the winding overhangs on one end face of the stator. The switching disk further including at least one temperature monitor mounted thereon for monitoring the temperature of the stator windings. The temperature monitor being seated in a holding pocket that is resiliently connected to the switching disk in such a manner that, when positioned in one of the stator grooves, it is resiliently biased into engagement with a stator winding.
Claims18
A stator arrangement for an electric motor, the stator arrangement comprising:
- a laminated stator core and an interconnection unit;
- the laminated stator core having portions defining stator grooves extending between end faces, at least one stator winding extending through each of the stator grooves and the end faces to form a winding overhang at each of the end faces;
- and
- covering the stator winding overhangs on one end face of the stator core, the interconnection unit further including a switching disk and comprising at least one temperature monitor mounted thereon to monitoring the temperature of the stator windings, at least one holding pocket being resiliently connected to the switching disk and the temperature monitor being received within the holding pocket, the holding pocket positioned in one of the stator grooves and being resiliently biased into engagement with one of the stator windings therein, whereby the temperature monitor monitors the temperature of the stator winding engaged by the holding pocket.
