Motor Pressure Circle Casting Parts Core Technology&Market Application of Motor

Introduction Of Railway Motor Pressure Circle

Pressure circle casting parts are the core of high-speed traction motor structures, and the manufacturing process and performance directly affect the reliability and service life of the motor.
Pressure casting process overview
Motor circle usually adopts a precision casting process; the mainstream techniques include sand casting, investment casting and pressure casting. Take investment casting as an example; its process covers mold design, wax mold forming, shell sintering, metal melting and pouring, post-treatment and other links. Casting materials are mainly made of high-strength ductile iron, high-temperature resistant alloy steel or lightweight aluminum alloy to ensure that the components have fatigue resistance, thermal conductivity and electromagnetic properties. The advantage of precision casting is that it can form complex structures (such as reinforcement and heat dissipation holes) at one time, reducing subsequent processing costs.

Key Technology Breakthrough of Railway Motor Pressure Circle

In modern, foundry technology through three major innovations to improve the quality of clamping rings: 1. The digital simulation, by using CAE software to optimize the design of the gating system, reduces the defects such as blow holes, shrinkage, yield up to 98% above; 2. Shape control sexual technology: by directional solidification process control material grain structure, make the compression ring tensile strength reached 600 mpa; 3. Green casting: using 3D printing mold alternatives to traditional wooden reduces material waste and shortens the production cycle by 30%.

Quality Control and Test of Railway Motor Pressure Circle

Casting parts need to pass strict inspection, including X-ray flaw detection (internal defects), three-coordinate measuring precision (size), fatigue test (life), etc. For example, the radial runout of the high-speed iron ring needs to be ≤0.05mm, the surface roughness Ra≤3.2μm, and some high-end products need to meet the ISO 8062 CT6 level accuracy standard.

Market Orientation and Trend of Railway Motor Pressure Circle

At the current, the motor pressure ring castings market scale has grown by more than 12%, mainly used in rail transit, new energy vehicles and the industrial electric field. Domestic foundry enterprises with cost advantages (30%-50% lower than imported parts) and rapid response ability gradually replace European and American suppliers. In the future, with the high power density of motors, casting parts will become thin-walled, integrated, and integrate sensing functions (such as embedded stress monitoring units) to create higher added value for business cooperation.
