Rail Motor

Introduction to Rail Motor and Accessories

Motor components for rail vehicles, including motor pressure ring, stator pressure ring, brackets, motor bases, and motor end cover, are critical for ensuring secure assembly and efficient operation of traction motors. These components are typically fabricated from cast steel or iron to meet the demanding requirements of railway applications.

Specifications of Stator Pressure Ring

Structure & Material & Quality
Material	Production process	Structure	Quality Control
Cold rolled silicon steel sheet, alloy steel	V-method production, water glass sand, coated sand, furan resin sand	Matching design of the pressure ring and stator core, optimization design of strength and heat dissipation performance	Dimensional tolerance and shape tolerance testing, non-destructive testing (such as ultrasonic testing)
Size & Weight
Gross Weight	thickness and outer diameter	Inner Diameter
80-250 kg	According to motor performance and structural requirements	Matches the outer diameter of the stator core, and the interference fit is determined according to the design
Environmental Suitability & Performance requirements
hardness	Corrosion resistant	Heat dissipation	Performance requirements
The hardness value is determined according to the material and application scenario, such as HB200-300 (Brinell hardness)	Excellent corrosion resistance, such as galvanizing, painting and other anti-corrosion treatments	Optimize heat dissipation performance to reduce temperature rise	The magnetic circuit is well closed, reducing hysteresis loss and bearing the transmission end load

Characteristics of Rail Motor and Accessories 

• Material Properties: High-strength cast steel/iron alloys offer excellent resistance to mechanical stress, thermal cycling, and environmental corrosion.
• Manufacturing Precision: Produced using V-process vacuum casting technology, which enables complex geometries, tight dimensional tolerances, and smooth surface finishes.
• Structural Integrity: Designed to withstand vibration, shock loads, and prolonged operational fatigue in rail environments.

Types of Rail Motor and Accessories 

• Motor Pressure Ring: Secure stator and rotor assemblies under rotational forces.
• Stator Pressure Ring: Maintain stator alignment and stability during motor operation.
• Brackets and Motor Bases: Provide rigid mounting points for motor installation.
• Motor End Cover: Seal motor housings to prevent ingress of debris and moisture.

Production Process of  Rail Motor and Accessories 

V-process casting lines utilize vacuum-sealed sand molds to shape molten metal, ensuring consistent quality and minimal material waste. Components undergo post-casting machining, heat treatment, and non-destructive testing to meet industry standards.

Applications of Rail Motor and Accessories 

Essential for high-speed trains, locomotives, and railcar motors, these components support power transmission, heat dissipation, and structural stability. They are validated for compliance with international rail safety standards (e.g., EN, ISO) to ensure compatibility across global projects.
