Example Embodiment

[0044] figure 1An embodiment of the present invention is shown in accordance with a stator having a temperature sensor (not shown). The stator shown is suitable for the same manner as the asynchronous motor, and the synchronous motor is also generated. The stator includes an insulating ring, a stator laminated core, a suitable winding, housing, and two windings having a rod-shaped conductor, wherein each having a winding head is disposed on the axial end of the stator. The region protruding in the axial direction is referred to as a winding head.

[0045] exist figure 1 The winding heads shown in the windings include a rod-like conductor, a connecting tab 11, an insulating plate 10, a temperature sensor 12 (not shown), a seal, and an insulating ring.

[0046] Specially, the rod-like conductor can be understood as a hairpin or an i-shaped head. The rod-like conductor can be designed as a single strand conductor or a multi-piece, specifically designed to shape-crimped strand. The r...

Abstract

The invention relates to a stator comprising at least one insulation disk (10), at least one interconnection piece (11) and at least one temperature sensor (12); the insulation disk (10) includes a holding element (13) for the temperature sensor (12), and the interconnection piece (11) includes a contact surface (14) for the temperature sensor (12); at least part of the interconnection piece (11) and at least part of the temperature sensor (12) are arranged and retained in the holding element (13); and the temperature sensor (12) is at least partially in planar contact with the contact surface (14) and is pressed against the contact surface (14) by a spring force and/or a clamping force.

Description

technical field [0001] The invention relates to a stator and a motor. Background technique [0002] From the document CN 205792061 U is known an electrical connection assembly for starting and stopping a generator, which comprises a temperature measuring assembly with a temperature sensor. The temperature sensor is arranged in a bore which extends into the temperature-measuring assembly and is arranged in the bore in a non-detachable manner and is thermally conductively connected to the bore wall of the bore. [0003] The conduction cross-section, which is effectively conductive, is narrowed through the holes. As a result, the electrical resistance increases in the temperature measurement region. This leads to locally higher temperatures than in the remaining conductors, with the result that the measured temperature values ​​are distorted. [0004] A stator with hairpin windings is described in document WO 2017 / 118786. The winding has a neutral point. The stator include...
