Holder for winding wires for stators of electric motors
View Patent ↗The invention relates to a holder for the winding wires for stators of electric motors consisting of a component to be disposed on the stator having means for holding and guiding the winding wires that run between the individual stator windings. According to the invention, the holder is designed as a part of a circuit board for connecting the phase windings.
1. A holder for wires connecting a plurality of stator coils on the stator of an electric motor, the holder comprising:
a wire routing element mounted coaxially on the stator;
a plurality of wire guide members extending axially from said wire routing element, each of said wire guide members having a channel to hold and position at least one wire connecting one stator coil to another stator coil of the same phase; and
a printed circuit board integral with said wire routing element, said printed circuit board having at least one solder pad to which wires extending from stator coils having a common phase are affixed.
2. The holder according to claim 1 , characterized in that the holder is made up of several layers of material ( 2 a - 2 d ).
3. The holder according to claim 2 , characterized in that the holder consists of several lamination layers ( 2 a - 2 d ).
4. The holder according to claim 1 , characterized in that the holder comprises an annular part ( 3 ) on which said plurality of wire guide members ( 4 ) are arranged and distributed, said printed circuit board extending radially away from said annular part.
5. The holder according to claim 4 , characterized in that the wire guide members ( 4 ) are formed from at least one layer of material ( 2 c , 2 d ).
6. The holder according to claim 1 , characterized in that the holder comprises a plurality of winding members ( 14 ) for the stator windings ( 11 ).
7. The holder of claim 1 in which the number of wire guide members corresponds to the number of stator coils.
8. The holder of claim 1 in which the number of solder pads corresponds to the number of stator coil phases.
9. The holder of claim 1 in which said wire routing element is coextensive with the stator.
