Subsection-armature motor stator and manufacturing process thereof

Abstract

The invention provides a subsection-armature motor stator and a manufacturing process thereof, and belongs to the technical field of motors. The problems that an existing motor stator is longer in magnetic circuit, poor in overall performance, complicated in structure, poor in insulativity, poor in heat dissipation, complicated in manufacturing process, low in cost performance and the like are solved. The subsection-armature motor stator comprises a shell, a heat dissipation system, a terminal structure, a sealing piece and multiple armature units arranged in the shell and distributed in a ring shape, wherein a placement space for the armature units is formed between the shell and the sealing piece; the heat dissipation system comprises an air inlet mechanism and a cooling channel; the airinlet mechanism can convey cold air to the cooling channel; the cooling channel surrounds the armature units; a heat conducting mechanism is arranged between the cooling channel and the armature units; an air outlet communicated with the cooling channel is also arranged on the shell. By adopting a resin embedding technology, the stator is high in overall structure, the insulativity, the deterioration performance and the heat dissipation performance are improve favorably, and the stator is simple and firm in structure and good in heat dissipation performance.

Description

technical field [0001] The invention belongs to the technical field of motors, and in particular relates to a segmented armature motor stator and a manufacturing process thereof. Background technique [0002] With the shortage of gasoline and oil energy and people's increasing attention to environmental issues, green and environmentally friendly electric vehicles will become an important way for people to travel in the future. However, the electric vehicle drive system is developing in the direction of high torque density, high efficiency, and wide speed ratio. Whether it is a traditional motor or a new type of motor, it must meet the most basic power performance requirements of an electric vehicle. Focus on torque density and efficiency. Rare earth permanent magnet motors, AC synchronous motors and switched reluctance motors are the main development directions. Rare-earth permanent magnet motors have the highest efficiency among all motors, because permanent magnets are u...
