Description

Technical Field

[0001] This utility model relates to the field of stator structure technology, specifically to a stator assembly for a water pump motor. Background Technology

[0002] Wound-rotor motors are a type of asynchronous motor. Their core structure includes a stator and a rotor. The stator consists of a silicon steel core and three-phase windings, which are wound with insulated enameled copper wire.

[0003] Currently, in low-power motors, there are generally two existing technologies for multi-parallel branch winding: 1. After semi-automatic winding, the individual branch lines are manually wound together and then welded. Due to the large number of ends in each branch line, the production efficiency is low and a lot of manpower is required. 2. After fully automatic winding, the terminals of each branch are individually soldered, and then soldered to each terminal through a busbar (PCB board) to connect the branches in parallel. This method requires adding a busbar, increasing costs and processes, and requires secondary soldering, resulting in low efficiency. Utility Model Content
