Abstract
Description
Technical Field
[0001] The invention relates to the field of motor preparation, and in particular to a motor stator winding, embedding and expanding integrated machine. Background Art
[0002] Electric machine (English: Electric machine, commonly known as "motor") refers to an electromagnetic device that realizes the conversion or transmission of electric energy according to the law of electromagnetic induction. It at least includes a stator and a rotor.
[0003] When preparing the stator, it is necessary to wind the coil on the stator. The common method is to embed the coil longitudinally on the stator manually or by a coil embedding machine. For some lightweight stators, the structure and power are small, and generally one coil embedding is sufficient, and there is no problem of multiple coil embedding. However, for the stator of a larger three-phase motor, the stator needs three coil embeddings to prepare the finished product. During the coil embedding, it can only be ensured that the coil enters the slot. During the second or third coil embedding, it cannot be ensured that the coil has enough space, which affects the subsequent coil embedding force, causes damage to the coil, and affects the motor performance.
[0004] The existing manufacturing of larger three-phase motor stators usually uses a winding and embedding machine and an expander at the same time. The stator needs to be shifted between the winding and embedding machine and the expander. After each winding is embedded in the winding and embedding machine, the coil end is expanded on the expander and the interphase insulation paper is pressed in. The stator with an incompletely fixed winding is easily damaged during movement. In addition, the stator is heavy and difficult to carry, and at least three manual operations are required, which is inefficient. In addition, for larger three-phase motor stators, the loading process and the transfer between different workstations are also difficult. Summary of the invention
