Anodized Black Aluminum Alloy Corrosion Resistant Motor Housing End Cover

Product Description

Product Description

Stepper motor end cover

The stepper motor end cover is a critical component designed to provide secure enclosure, structural stability, and environmental protection for the motor's internal assembly. Made from high-strength materials such as die-cast aluminum or engineering plastics, it ensures reliable shielding against dust, moisture, and mechanical interference while maintaining precise alignment of the rotor and stator. With optimized design for heat dissipation and easy integration, this cover supports long-term motor performance and durability in demanding motion control applications.

Ideal for use in automation, robotics, CNC machinery, and precision instruments, the end cover features mounting compatibility, corrosion resistance, and customizable options such as sealed or vented configurations. Its robust construction not only extends motor life but also enhances operational safety and efficiency, making it an essential element in step motor systems where reliability and accuracy are paramount.

Product Name	Stepper Motor End Cover (Also referred to as motor housing, casing, etc., depending on the application scenario)
Primary Material	Aluminum Alloy: ADC12 (A383), A360, A380, AlSi9Cu3, AlSi12, etc. (ADC12 is commonly used) Optional Materials: Zinc Alloy (e.g., Zamak 3, Zamak 5), suitable for higher precision and strength requirements
Manufacturing Process	High-pressure die casting, sometimes combined with innovative processes like local extrusion for reinforcement. The typical process flow includes: smelting, die casting, degating, deburring, heat treatment, CNC precision machining, cleaning, etc.
Key Dimensions	Outer Diameter: Φ20mm - Φ150mm Height: 5mm - 50mm Wall Thickness: Minimum achievable wall thickness of 0.8mm. Recommended design thickness is 1.2mm - 3.0mm.
Weight	10g - 500g (depending on size and design)
Tolerance Standards	Key Dimension Tolerances: For critical dimensions like bearing bore diameter and mounting hole pitch, tolerances can be guaranteed within ±0.02mm after CNC machining. Geometric Tolerances: Flatness, concentricity, perpendicularity, etc., can be controlled per drawing requirements, commonly achieving 0.03mm - 0.05mm after machining.
Mechanical Properties	Tensile Strength: ≥ 320 MPa Yield Strength: ≥ 160 MPa Elongation: ≥ 3.5% Hardness: ≥ 80 HB
Surface Treatment	Anodizing: Available in natural color, black, or other colors. Enhances corrosion resistance and wear resistance. Powder Coating: Offers various colors (RAL/Pantone color charts available). Provides aesthetic appeal and uniform coating. Plating: Nickel, chrome, etc. (Applicable to zinc alloy parts).
Surface Finishing	Optional Methods: 1. Basic Treatment: Manual/Vibratory deburring, sandblasting (creates a uniform matte surface). 2. CNC Precision Machining: Integrated turning, milling, drilling, and tapping ensures extremely high precision for critical assembly dimensions like bearing seats, register surfaces, and screw holes.
