Ventilated Motor Shells
Produced by Jiangsu Yufeng Electric Co., Ltd, a motor housing manufacturer covering stamping, welding assembly, machining, and surface treatment within a single production system.
Ventilated Motor Shells from Jiangsu Yufeng Electric Co., Ltd are motor housings engineered with structured air passage openings that support heat exchange during motor operation. Each shell is formed through a stamping process, joined by welding assembly, refined by machining, and finished with surface treatment to reach the dimensional and surface requirements of household appliance motors, industrial drive motors, new energy vehicle motors, and special equipment motors. Wall sections, mounting points, and vent layouts are configured according to motor frame size and airflow requirement, supporting a range of housing diameters and lengths. Production draws on stamping lines, automated welding equipment, machining centers, and inspection instruments operating within one facility, reducing the handoff points between processing stages. Engineering staff with an average of over 20 years of experience support drawing review, tooling development, and process adjustment from prototype through mass production. With 40 years concentrated on motor housing manufacturing and an annual capacity above 5 million units, the shells are supplied in volumes suited to both development-stage orders and continuous production programs.
Core Advantages
Integrated Process Chain
Stamping, welding assembly, machining, and surface treatment are carried out in one facility, limiting transfer time and variation between stages.
Established Manufacturing Base
Forty years directed at motor housing production has built tooling, fixture, and process references applicable across housing sizes and wall configurations.
Engineering Support
An engineering team averaging over 20 years of experience supports drawing review, tooling planning, and process adjustment from sample stage to volume production.
Volume Capacity
Annual production capacity above 5 million units allows for scheduling that accommodates trial orders, phased ramp-up, and steady recurring volumes.
Inspection Coverage
Inspection instruments are applied at stamping, welding, and machining stages to track dimensional and surface condition through the production sequence.
Customer Base Across Sectors
