Problems solved by technology

However, in actual operation, the turns of some parts of the stator coil do not meet the design requirements, and the turning radius at the nose of the lead wire is greater than the design value, especially the stator coil has many strands and turns, and the cross-sectional size between turns is large. In the case of constant shape and size, the total length of the produced stator coil exceeds 8-20mm
It is a waste of raw materials, and does not meet the design size requirements. The amount of grinding of the winding die increases the labor intensity of the operator, wastes time and effort, and causes technical problems such as increased working hours and costs.

Embodiment 1

[0028] The winding length control method of the high-voltage motor stator coil coil uses a coil winding machine for coil coil winding. When the stator coil is wound on the coil winding machine, firstly, the copper coil wires are hoisted on the wire coils in sequence according to the coil technical requirements. On the bracket, fix the copper wires side by side with an aggregator and adjust the tension of the wires; fix the winding mold on the winding machine, and the winding mold will leave a copper wire rebound of 1-3mm at the end of the lead nose to control Winder speed for coil winding. When winding the coil, flatten the wire so that it is close to the side of the winding core, so that the inside and outside of the wire are tightly wound and the gap between the coil noses is reduced.

Abstract

The invention relates to a method and a device for controlling the winding length of a motor stator coil type coil, belonging to the technical field of motors. The method for controlling the winding length of a motor stator coil type coil comprises the following steps: firstly, sequentially hoisting copper disc leads on a lead bracket; fixedly collecting the copper leads together in parallel by acollector and adjusting the tension of the leads; fixing a winding die on a winding machine, retaining 1-3 mm of copper lead rebound at the end parts of lead noses by the winding die and controlling the speed of the winding machine to wind the coil. The winding die fixed on the winding machine of the device for controlling the winding length of the motor stator coil type coil has an adjustable structure, and a die core is arranged between an inner blocking plate and an outer blocking plate; an inner die core is designed into two sections; the inner die core at the lead end is fixed on the outer blocking plate, and the inner die core subsection at the other end and the outer blocking plate are made into a structure with a guide rail. The invention has the advantages of simple and convenient process, high control precision and production efficiency, good coil winding quality, simple die structure, and the like.

Description

technical field [0001] The invention belongs to the technical field of motors, and in particular relates to a method and a device for controlling the winding length of a motor stator coil type coil. Background technique [0002] At present, in order to reduce the production cost of high-voltage motors and tooling molds for hydropower products, the stator coil of the motor mostly adopts a coil coil structure. In the theoretical design, the corner radius is usually R25 for the nose and R33 for the lead wire nose. However, in actual operation, the turns of some parts of the stator coil do not meet the design requirements, and the turning radius at the nose of the lead wire is greater than the design value, especially the stator coil has many strands and turns, and the cross-sectional size between turns is large. In the case of constant shape and size, the total length of the produced stator coil exceeds 8-20mm. That is to say, raw materials are wasted, and it does not meet the...
