Problems solved by technology

[0002] In related technologies, such as rotor components of series-excited motors, the commutator and the end insulation of the rotor core are assembled as separate parts, and the commutator needs to be assembled on the rotor shaft by press-fitting in a special process. Both materials and processes require special quality control, and the production cost is relatively high
Especially for the rotor components of double-layer insulation motors, the requirements for fitting tolerances are strict, and there are hidden dangers of fine cracks and glue overflow

Abstract

The invention discloses a rotor assembly, a motor and a method for manufacturing the rotor assembly. The rotor assembly comprises a rotor shaft, a rotor core, a commutator sheet and an insulator, wherein the rotor core sleeves the rotor shaft, the commutator sheet sleeves the rotor shaft, and insulation material is filled in the space between the commutator sheet and the rotor shaft and between the rotor core and the rotor shaft to cover the rotor core along the axial end face of the rotor core. The rotor assembly is formed once, the production steps are less, the production cost is low, and the quality is reliable.

Description

technical field [0001] The present invention relates to the technical field of motors, in particular to a rotor assembly, a motor with the rotor assembly and a manufacturing method of the rotor assembly. Background technique [0002] In related technologies, such as rotor components of series-excited motors, the commutator and the end insulation of the rotor core are assembled as separate parts, and the commutator needs to be assembled on the rotor shaft by press-fitting in a special process. Both materials and processes require special quality control, and the production cost is relatively high. Especially for the rotor components of double-layer insulation motors, the requirements for fit tolerances are strict, and there are hidden dangers of fine cracks and glue overflow. Contents of the invention [0003] The present invention aims to solve one of the above-mentioned technical problems in the related art at least to a certain extent. Therefore, the present invention ...
