AI Technical Summary

Problems solved by technology

This creates significant limitations in mechanical design (for example, with regard to the number of slots to accommodate the windings) or in the maximum voltage achievable
[0010] Also, it is not possible to upgrade (by increasing the operating voltage) the mechanics of e.g. generators, because the upgraded voltage is too high for the practical distance between adjacent covers 5
[0011] Additionally, the assembly of the two parts 6, 7 of the cover 5 and the simultaneous provision of the putty is typically very time consuming

Abstract

The electric machine has a stator (10) with windings (2) connected to phase connections (4). An insulating cap (5) protects the reciprocally connected portions of the phase connections (4) and windings (2). The insulating cap (5) has a box-shaped body (15) with an opening (16) for the introduction of a winding (2) within it. The body (15) defines a seat (17) housing the phase connection (4). The seat (17) is realised in one piece with the body (15).

Description

technical field [0001] The invention relates to an electric machine, an insulating cover and a method for realizing the insulating cover. Background technique [0002] Figure 1 shows a conventional connection between windings 2 and phase connections 4 (phase rings) of a stator of an electric machine, eg a generator. [0003] The connection typically comprises a conductive member 3 which is brazed to the winding 2 on one side and to the phase connection 4 on the other side. [0004] The insulating cover 5 is provided over the end of the winding 2, the conductive member 3 and the phase connection part 4 to insulate and protect components accommodated therein. [0005] As shown, a conventional cover 5 consists of two components; a first component 6, which houses the ends of the windings 2 and most of the conductive component 3, and a second component 7, which encapsulates the The phase connection 4 also has an end that overlaps the boundary of the first component 6 at a regio...
