Problems solved by technology

[0003] However, due to the inconsistent failure mode of the existing starter when overloaded, the failure point cannot be determined artificially, resulting in high product risk. When the overload current of the starter is low, the speed of the armature to generate heat is lower than the speed of dissipating heat, so it is not easy to short circuit , there is a risk of ablation of the starter during long-term operation, and because the existing armature winding is protected by insulating varnish, it is difficult to achieve short circuit by itself

Abstract

The invention provides an armature assembly and a starter, relates to the technical field of starter overload protection, and aims to optimize the structure of the armature assembly to a certain extent and ensure the consistency of overload failure modes of the starter. The invention provides an armature assembly which comprises an iron core, an armature winding and an abutting piece. The armature winding is wound on the iron core, a first containing space and a second containing space are defined at the two ends of the iron core respectively, and the abutting piece is arranged in the first containing space and / or the second containing space and abuts against the armature winding.

Description

technical field [0001] The invention relates to the technical field of starter overload protection, in particular to an armature assembly and a starter. Background technique [0002] The overload protection of the starter is to open the circuit of the starter, which is mainly realized by the fusing of the fuse rod of the brush holder, and the fusing of the fuse rod requires the generation of a large current. The reason for the large current is the short circuit of the internal circuit of the starter. [0003] However, due to the inconsistent failure mode of the existing starter when it is overloaded, the failure point cannot be determined manually, resulting in a higher product risk. When the overload current of the starter is low, the speed at which the armature generates heat is lower than the speed at which it dissipates heat, so it is not easy to short-circuit , the starter runs for a long time, and there is a risk of ablation, and because the existing armature winding i...
