Application Fit and Material Considerations
Steel motor housings are chosen for their strength, thermal conductivity, and cost-effectiveness. Our housings are typically made from SPCC, ST12, or DC01 cold-rolled steel, depending on your requirements for formability, weldability, and surface finish.
- Household appliances: Washing machines, air conditioners, refrigerators, and kitchen appliances benefit from our thin-wall designs that reduce weight and improve heat dissipation.
- Industrial drives: For pumps, fans, compressors, and mining motors, we offer housings with reinforced bases and brackets to withstand continuous vibration and shock.
- New energy vehicles: Our housings meet stricter quality and consistency standards, with process control aligned to IATF 16949 principles for automotive applications.
- Special equipment: We customize structures for unique mounting, sealing, or cooling requirements, including ventilation holes for axial airflow.
Critical Specifications and Quality Assurance
We control critical dimensions such as inner diameter, roundness, and end-face parallelism to ensure proper stator fit and bearing alignment. For example, our ID 120 mm housing maintains roundness within 0.08 mm, and end faces are machined to a parallelism tolerance of 0.1 mm.
Our quality system includes incoming material inspection, in-process checkpoints at stamping, welding, machining, and coating stages, and final inspection with custom gauges. Each batch is traceable to raw material lots, machines, and operators, ensuring full traceability and rapid corrective action.
We are ISO 9001:2015 certified, and for automotive customers, we implement additional process controls and traceability per IATF 16949 standards.
Configuration Options and Customization
We understand that every motor design is unique. Our customization capabilities include:
- Dimensional adjustments: Inner diameter, height, wall thickness, and overall length can be modified to match your stator and rotor stack.
- Mounting features: Bases, T-bases, brackets, studs, or screws can be welded or machined to simplify assembly and reduce part count.
- Surface treatment: Choose from electrophoretic coating (e-coating) or powder coating for corrosion resistance and aesthetic finish.
- Ventilation design: Axial or radial cooling holes can be added to optimize heat dissipation for your duty cycle.
For non-standard projects, our engineering team works with you from drawing review to sample development, ensuring manufacturability and performance.
Production Capacity and Lead Times
With an annual production capacity exceeding 5 million units, we handle large-volume orders as well as small-batch, multi-variety production. Our continuous stamping process achieves material utilization over 92%, and in-house coating lines reduce outsourcing lead times.
For standard custom samples, we deliver within 3–10 working days; complex projects complete first articles within 15 days. Quotations are provided within 2–3 working days after receiving your drawings and specifications.
Information We Use to Configure Your Solution
To prepare an accurate quotation and engineering proposal, please provide the following:
- Product drawings or detailed specifications (dimensions, material grade, surface treatment)
- Estimated annual demand or quantity per batch
- Special technical requirements (e.g., protection level, precision tolerances, vibration resistance)
- Any existing tooling or assembly constraints
With this information, we can recommend the most suitable housing design, manufacturing process, and cost-effective solution.
Frequently Asked Questions
Q: What types of steel motor housings do you produce?
A: We produce steel motor housings for household appliances (washing machines, air conditioners, refrigerators), industrial drives (compressors, fans, pumps), new energy vehicles, and special equipment. Our range includes thin-wall designs for portable tools and heavy-wall options for high-vibration applications.
Q: Can you customize the housing dimensions and mounting features?
