Inner Diameter 140 Steel Motor Housing With Three Brackets

Product Description

This steel motor housing features a precision-engineered structure with an inner diameter of 139.3mm, height of 114.3mm, and a wall thickness of 1.5mm, achieving light weight while maintaining sufficient strength.
·Ventilation holes on both ends establish an efficient axial air cooling channel, allowing airflow to pass smoothly through the housing interior to promptly dissipate heat generated by the stator and rotor, effectively reducing temperature rise and extending the motor's continuous operation life. 
·Three welded mounting feet are provided on the bottom, utilizing a three-point support structure that not only ensures stable installation and strong vibration resistance but also adapts to uneven mounting surfaces, simplifying the overall equipment assembly process. Compared to four-point supports, the three-point foot design is easier to level while reducing material usage and overall weight. 
·This product is particularly suitable for industrial fans, exhaust equipment, agricultural machinery motors, food processing equipment, packaging machinery, and other medium-to-small power equipment with high heat dissipation requirements and compact installation spaces, providing users with a reliable motor housing solution that offers efficient heat dissipation, convenient installation, and stable operation.

    Application of New Die-Casting Processes to Enhance the Overall Performance of Motor Housings

    With ongoing optimizations in die-casting processes, these techniques are now widely used in the production of motor housings. The new process results in a more compact overall structure, significantly improves the surface flatness and one-piece molding quality of the housing, and optimizes the design of the internal heat dissipation channels. Field tests have shown that these motor housings offer improved heat dissipation efficiency and structural stability under normal operating conditions, making them better suited for the assembly and long-term operation of small and medium-sized power motors. They are currently being gradually adopted in the manufacturing of general-purpose electromechanical equipment.

    Upgraded Motor Housing Protection Rating for Complex Operating Environments

    To meet the demands of outdoor, industrial, and humid environments, the motor housing has undergone a new round of upgrades in sealing and protection design. By optimizing the splicing structure and adding sealing accessories, the product effectively enhances dustproof and waterproof capabilities, making it suitable for dusty, high-humidity, and light-splash environments. Additionally, the housing is made of impact-resistant material, enhancing its resistance to vibration and impact. This further expands the application scenarios for motor-related products and meets the assembly requirements of sectors such as construction machinery and outdoor conveying equipment.

    Lightweight Materials Become a Trend, Balancing Strength and User Experience

    Lightweight design has become a development trend in the electromechanical accessories industry. New alloy materials are now being used for motor housings. While maintaining overall mechanical strength and compression resistance, the product’s weight has been reasonably reduced. This facilitates handling and assembly during production and reduces the load on the entire machine, contributing to energy-efficient operation. Currently, lightweight motor housings are gradually becoming widespread in applications such as home appliances, small automation equipment, and automotive motors.
