AI Technical Summary

Technical Problem

The reduced space inside modern rotating electric machines can lead to interference between the wire harness extending from the temperature sensing element and the power line, causing loose connections and damage to welds.

Method used

A rotating electric machine design that incorporates a harness holder to guide the wire harness towards the inner peripheral wall of the case, preventing interference with the power lines and maintaining secure connections.

Benefits of technology

The harness holder effectively suppresses interference between the wire harness and power lines, preventing damage to welds and ensuring reliable connections within the rotating electric machine.

Abstract

To inhibit interference between power lines and wire harnesses in a case of a rotary electric machine.SOLUTION: A rotary electric machine includes a stator which is housed in a case and from which power lines are drawn out. The stator is equipped with a temperature detection element. The rotary electric machine includes a harness pressing part that guides, toward an inner peripheral wall of the case, wire harnesses extending from the temperature detection element. The harness pressing part is disposed on a terminal base which is provided on the case. The power lines drawn out from the stator are connected to the terminal base.SELECTED DRAWING: Figure 9
