As a dedicated manufacturer with a modern facility in Suzhou, Jiangsu, we at Jiangsu Manqi Machinery are proud to present our robust S Series Worm Helical Geared Motor. Engineered for demanding industrial applications, this motor combines the high torque and self-locking capability of a worm gear with the efficiency and smooth operation of helical gears, all encased in a durable cast iron housing. This design is ideal for customers in Eastern Europe, Southeast Asia, Africa, and South Asia who require reliable, long-lasting power transmission solutions for their machinery. Our focus on quality manufacturing and export-oriented service ensures you receive a product built for performance and durability in diverse operating environments.
The S Series represents a significant advancement in geared motor technology. The integration of worm and helical gears within a single reduction stage allows for a compact design that delivers high reduction ratios and substantial output torque. The cast iron housing is not merely a protective shell; it is a critical component that provides exceptional rigidity, dampens vibration and noise, and ensures superior heat dissipation. This results in a motor that operates more quietly, runs cooler, and maintains precise alignment of internal components over a longer service life, even under continuous heavy loads.
Key Technical Features and Advantages:
- Dual-Gear Technology: The primary helical stage offers high efficiency, while the secondary worm stage provides the high reduction ratio and optional self-locking feature, creating a versatile power package.
- Robust Cast Iron Construction: The housing offers unparalleled strength and resistance to deformation, protecting the precision gearing from misalignment caused by shock loads or mounting stresses.
- Optimized Thermal Management: Cast iron's excellent thermal conductivity helps dissipate heat generated during operation, contributing to stable performance and extended lubricant life.
- Wide Configuration Range: Available in six frame sizes (S57 to S107), this series covers a broad spectrum of power and torque requirements, making it suitable for a vast array of applications.
- High Protection Rating: Standard IP55 protection guards against dust and water jets, with IP65 available for more challenging environments, ensuring reliability in washdown or outdoor settings.
The benefits to your operation are clear. You gain a drive solution that reduces downtime through its rugged design, lowers operational noise for a better working environment, and offers flexible mounting and integration due to its standardized dimensions. The high torque density means you can often select a smaller frame size than with alternative technologies, saving space and potentially cost.
Below is a summary of the primary specifications across the S Series range:
| Model Series | Approx. Output Torque Range (Nm) | Input Power Range (kW) | Reduction Ratio Range (i) |
|---|---|---|---|
| S57 / S67 | Up to 500 Nm | 0.09 - 1.5 kW | 5 - 100 |
| S77 / S87 | Up to 2000 Nm | 0.75 - 7.5 kW | 5 - 100 |
| S97 / S107 | Up to 5000 Nm | 4.0 - 22 kW | 5 - 100 |
Common Applications: This motor is exceptionally well-suited for applications requiring high torque at low speeds and reliable holding capability. Typical uses include:
- Conveyor Systems: For bulk material handling in mining, agriculture, and packaging.
- Mixers and Agitators: In chemical, food processing, and pharmaceutical industries.
- Construction Machinery: Driving winches, slewing mechanisms, and lifting devices.
- Packaging Machinery: For indexing, lifting, and rotary table drives.
- Wastewater Treatment: Operating screw conveyors, screens, and aerators.

Frequently Asked Questions (FAQ)
Q1: What is the main advantage of a worm and helical gear combination over a standard worm gear motor?
A1: The hybrid design improves overall efficiency compared to a double-worm or single-worm design. The helical primary stage is more efficient, while the worm secondary stage provides the high reduction and self-locking. This results in better energy utilization and less heat generation.
Q2: Does the "self-locking" feature mean the output shaft cannot be back-driven at all?
A2: The self-locking capability is a function of the worm gear's lead angle. While it provides a high resistance to back-driving, it is not an absolute brake. For applications requiring a guaranteed hold, a mechanical brake is recommended as an optional addition.
Q3: What type of lubrication is used, and what are the maintenance intervals?
A3: The gearbox is typically factory-filled with a high-performance synthetic polyglycol or mineral-based gear oil suitable for a wide temperature range. Under normal operating conditions, the first oil change is recommended after 500-1000 running hours, with subsequent changes every 4000-8000 hours, depending on the operating environment and load.
Q4: Can the motor be supplied with different input voltages and frequencies?
A4: Yes. While standard motors are often configured for common three-phase voltages (e.g., 380V/50Hz or 460V/60Hz), we can provide motors tailored to various regional standards, including single-phase options. Please specify your requirements during inquiry.
Q5: Are flanged output shafts or other mounting variations available?
A5: The standard configuration is a foot-mounted unit with a keyed output shaft. However, flange mounts (e.g., IEC standard B5 or B14) and hollow output shafts are common optional variants that can be discussed based on your application needs.
Q6: What is the typical lead time for an order of these geared motors?
A6: For standard models and configurations, we generally maintain a lead time of 4-6 weeks for production and shipment. This can vary based on order quantity and specific customization requests. We provide accurate timelines upon receipt of a formal inquiry or purchase order.
Q7: How do I select the correct model (S57, S67, etc.) for my application?
A7: Selection requires knowing your required output torque (Nm), output speed (RPM), input power (kW) or motor speed, duty cycle, and ambient conditions. Our technical team can assist with this selection process if you provide these key parameters.
Q8: What after-sales support do you offer?
A8: We provide comprehensive technical documentation, including dimensional drawings and installation manuals. Support is available for installation guidance and troubleshooting. A standard warranty period covers manufacturing defects, with details provided with the product.
