Introduction of The Stator Press Ring For Railway Traction Motors

The stator press ring is a critical structural component used in railway traction motors. It is mainly installed at the stator end to firmly secure the stator core and end windings, withstand strong electromagnetic forces, suppress vibration, and ensure long-term operational stability of the motor.

In high-speed trains, heavy-haul locomotives, and urban rail vehicles, traction motors operate under high load, high temperature, and frequent start-stop conditions. A reliable stator press ring plays a key role in maintaining motor safety, efficiency, and service life.

1 Key Functions of the Stator Press Ring

Secure and fix stator end windings

Withstand high electromagnetic and mechanical forces

Reduce vibration and operating noise

Maintain dimensional stability under high temperature

Improve overall motor operational reliability

2. Material & Manufacturing Process

Our stator press rings for traction motors are manufactured using carefully selected materials and controlled processes to meet the demanding working conditions of railway equipment:

Material Options: Alloy steel, cast alloy (customizable)

Manufacturing Process: Casting or forging + CNC machining

Heat Treatment: Optional based on mechanical performance requirements

Surface Treatment: Anti-corrosion coating available

All processes are strictly controlled to ensure strength, dimensional accuracy, and long-term durability.

3. Quality Control & Inspection

Each stator end press ring is subjected to strict quality inspection before delivery, including:

Dimensional inspection
