Product Overview
The GH/GV Series Low-Rpm AC Gear Motor, an SL-branded drive solution, is designed for applications requiring low rotational speed and high torque. With a power range of 1.5hp to 4hp (equivalent to 100W to 3000W) and a 160mm rotor, it supports both single-phase and three-phase power supplies (110V, 220V, 380V AC), adapting to diverse industrial power configurations. Its working principle relies on multi-stage gear transmission—small gears drive large gears to reduce speed and increase torque—making it ideal for CNC machines, petrochemical equipment, rubber processing, packaging lines, and household appliances. The motor’s compact structure, low noise, and high bearing capacity ensure stable operation in both industrial and commercial scenarios.
Product Advantages
Low Rpm & High Torque
Through multi-stage gear transmission, the motor achieves low rotational speed while significantly increasing output torque, meeting the needs of equipment that requires slow, powerful operation (e.g., rubber mixers, packaging line conveyors).
The 160mm rotor enhances torque output stability, avoiding torque fluctuations during long-term operation, which is critical for precision equipment like CNC lathes.
Flexible Voltage Adaptation
Supports both single-phase (110V, 220V) and three-phase (380V) AC power, making it suitable for regions with different power grids (e.g., 110V in North America, 220V/380V in Asia and Europe). No additional voltage converters are needed, reducing setup costs.
Easy Maintenance & Long Durability
Simple maintenance requirements: only regular checks of lubricating oil quality/level, gear wear, and equipment cleanliness are needed, minimizing downtime for maintenance.
The gear system uses wear-resistant materials, and the motor housing is treated for corrosion resistance, extending service life even in harsh environments like petrochemical plants.

FAQ
Q1: Can the motor’s speed be adjusted if I need variable low speeds?
A1: Yes. The motor is compatible with variable frequency drives (VFDs). By connecting a VFD, you can adjust the speed within a low-rpm range (e.g., 50-500 RPM) to meet different production needs.
Q2: What voltage should I choose for my region?
A2: For North America (110V single-phase), select the 110V model; for Asia/Europe (220V single-phase or 380V three-phase), choose 220V or 380V models. The motor automatically adapts to 50Hz/60Hz, so no frequency concerns.
Q3: How often should I replace the lubricating oil?
A3: Under normal use (8 hours/day operation), replace the lubricating oil every 6 months; in heavy-duty use (24 hours/day), replace it every 3 months. Always use the recommended industrial gear oil to ensure gear performance.
Q4: Is the motor suitable for food packaging equipment (which requires hygiene)?
A4: Yes. The motor’s housing is easy to clean, and we offer optional food-grade anti-corrosion coatings for food packaging applications, ensuring compliance with hygiene standards.
