Abstract
An electric machine includes a core with a plurality of slots. A plurality of electric conductors are positioned in the slots. Each of the plurality of electric conductors includes a U-turn portion extending between two in-slot portions and connection ends extending from the in-slot portions. The connection ends are positioned on an opposite end of the core from the U-turn portions. A plurality of insulation tubes are positioned in the plurality of slots. The in-slot portions of the electric conductors extend through the insulation tubes.
Claims20
An electric machine comprising:
- a core with a plurality of slots;
- a plurality of electric conductors positioned in the slots, each of the plurality of electric conductors including a U-turn portion extending between two in-slot portions and connection ends extending from the in-slot portions, the connection ends extending from an opposite end of the core from the U-turn portions;
- and
- a plurality of insulation tubes positioned in the plurality of slots with the in-slot portions of the electric conductors extending through the insulation tubes.
A method of making an electric machine comprising:
- inserting a plurality of insulation tubes into a plurality of slots in a stator core;
- inserting a plurality of electric conductors into the plurality of insulation tubes in the slots of the stator core such that in-slot portions of the plurality of conductors are positioned in the plurality of slots, each of the plurality of electric conductors including a U-turn portion extending between two in-slot portions and connection ends extending from the in-slot portions, the connection ends extending from an opposite end of the stator core from the U-turn portions;
- and
- joining adjacent connection ends of the plurality of electric conductors.
An electric machine comprising:
- a stator core with a plurality of slots;
- a plurality of electric conductors positioned in the slots, each of the plurality of electric conductors including two connection ends and at least one in-slot portion, the connection ends extending from at least one end of the stator core;
- and
- a plurality of insulation tubes positioned in the plurality of slots with the in-slot portions of the electric conductors extending through the insulation tubes, each of the plurality of insulation tubes including a plurality of channels with the in-slot portion of one of the plurality of electric conductors extending through each of the plurality of channels, wherein each of the plurality of channels has a rectangular cross-section and is void of openings from a first end to a second end of the insulation tube.
