Technique for packaging long stator iron core assembly

Abstract

The invention is a long stator iron core component packaging process, belonging to electric machine manufacturing technical field, comprising the steps of: a. putting solidified long stator iron core component together with connecting piece into an epoxy resin or unsaturated polyester resin injection mould and heating to 60-200 deg.C, preserving heat for 2-60 min; b. pressurizing the injection mould while vacuumizing and pouring epoxy resin or unsaturated polyester resin and keeping 2-60 min at a pressure of 1-5MPa; c. opening the injection mould and putting injected piece into an oven or baking channel for post-solification and making the long station iron core packaged piece. And the invention has advantages of convenient operating, saving labor and time, simplifying injection device, etc. and the surface of the packaged long stator iron core component is compact, and smooth and birght and clean, and has no air holes and defects, and the invention is especially applied to packaging long stator iron core components for high speed magnetic suspension train and driving motor iron core components for city railway traffic.

Description

technical field [0001] The invention relates to a long stator core assembly packaging process, which belongs to the technical field of motor manufacturing. Background technique [0002] The long stator linear synchronous motor is composed of a stator (armature; track part) and a mover (magnetic pole; vehicle part). It has a compact structure, high efficiency and power factor, and belongs to a core technology in high-speed maglev trains. The process technology requires very high. As the key component of the propulsion system and the maglev system, the long stator of the linear synchronous motor is responsible for the three functions of suspension, propulsion, and vehicle power supply, and plays a vital role in the high-speed maglev train. The packaging of long stator core components used in existing high-speed maglev trains mainly adopts vacuum casting and vacuum automatic pressure gel technology. Bubbles or defects affect the compactness and flatnes...

Problems solved by technology

The packaging of long stator core components used in existing high-speed maglev trains mainly adopts vacuum casting and vacuum automatic pressure gel technology. Bubbles or defects affect the compactness and flatness of the component surface; the vacuum automatic pressure gel process needs to put the mold in a vacuum tank (chamber) for vacuuming and repressurization, which requires high processing equipment and is difficult to operate.
