Problems solved by technology

[0003] A disadvantage of the prior art is that the structural unit formed by the stator segments held together in the form of a ring is fastened in a predetermined position when fastened in the assigned housing and must be held in order to be able to achieve fixation
As a result, the fixing of the stator segments in the housing and thus the installation of the electric motor is cumbersome and complicated

Embodiment Construction

[0036] figure 1 An electric motor 100 , which is embodied as an example as an inner rotor motor, is shown, having an inner rotor 110 arranged on a motor shaft 120 and a segmented outer stator 160 , which are illustratively arranged in a housing 150 . According to one embodiment, the segmented outer stator 160 has a plurality 170 of annularly arranged stator segments, illustratively twelve stator segments. The twelve stator segments are preferably designed in such a way that they can be joined together annularly, wherein the respective adjacent stator segments in the circumferential direction of the outer stator 160 or the housing 150 are preferably positively connected to each other or fixed to each other, for example by means of A suitable groove-lug-connection 195 is realized. In particular, the twelve stator segments are preferably formed at least substantially identically. Therefore, for reasons of simplicity and clarity of illustration, only one individual stator segme...

Abstract

In an electric motor (100) having a rotor (110) and a stator (160) arranged in a housing (150), the stator is formed from a plurality of annularly arranged stator segments (171), wherein at least one stator segment (171) has a configured stator segment core (190). The stator segment core is provided with at least one insulator (130) which is provided with a single winding (191) arranged on the stator segment (171). The at least one insulator (130) comprises at least one locating element (140) facing the housing (150). The locating element extends towards the housing (150) from the at least one stator segment core (190) at least partially. At least one connector for force transfer cooperation is formed between the stator (160) and the housing (150).

Description

technical field [0001] The invention relates to an electric motor with a rotor and a stator arranged in a housing, the stator being formed from a plurality of annularly arranged stator segments, wherein at least one stator segment has an associated stator segment core, the stator The segment core is provided with at least one insulator on which a single winding assigned to the stator segment is arranged. Background technique [0002] Such electric motors are known in the prior art, the stator of which has a plurality of stator segments. The stator segments are arranged annularly and are held together by an annular retaining ring arranged on the outer circumference of the stator segments and are thus connected to one another. Such annularly held stator segments can then be arranged as a structural unit in the associated housing and fixed. [0003] A disadvantage of the prior art is that the structural unit formed by the stator segments held together in the form of a ring is...
