Embodiment Construction

[0044] figure 1An embodiment according to the invention of a stator with a temperature sensor (not shown) is shown. The illustrated stator is suitable for generating a rotating magnetic field for an asynchronous motor as well as for a synchronous motor. The stator comprises an insulating ring, a laminated stator core, an assembled winding with rod-shaped conductors, a housing and two winding heads, one winding head each being arranged at an axial end of the stator. The area that protrudes axially from the stator is called the winding head.

[0045] exist figure 1 The winding head shown in includes rod-shaped conductors, connecting tabs 11, insulating plates 10, temperature sensors 12 (not shown), gaskets and insulating rings.

[0046] In particular, rod-shaped conductors are to be understood as hairpins or I-shaped pins. The rod conductor can be designed in one piece as a single-strand conductor or as a multi-piece, in particular form-pressed, stranded wire. The rod condu...

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...
