Modular Frame with Dual Sizes
The 120W Micro Gear Motor is available with two flange sizes: 90*90mm and 100*100mm. The overall length of the complete unit ranges from 245mm to 280mm, with a self-weight of 3.8kg. It accommodates retrofitting compatibility for existing equipment and assembly requirements for large bases of brand-new heavy-duty machinery, and complies with various frame mounting standards.
High-Current Matching with Large-Capacity Capacitors
The rated power of the Micro Gear Motor is 120W, compatible with global single-phase mains power of 50/60Hz, with an operating current ranging from 0.31 to 1.9A. It supports a wide capacitor selection range of 6~30uF, boasting sufficient current reserve for heavy-load frequent start-stop working conditions, featuring smooth startup without stalling or jittering.
Ultra-High Torque Design with Optional Input Shafts
Our AC gear motor input shafts are available in two sizes: 12mm and 15mm, with a reinforced 15mm gearbox output shaft provided as standard for all models. It covers a full range of gear ratios from 1:3 to 1:300 and delivers output torque ranging from 2.11 Nm to 31 Nm, making it suitable for high-load transmission applications such as heavy-duty conveying, large-tonnage tilting and lifting.
Multi-Layer Pressure-Resistant Sealing for Zero Oil Leakage
The gearbox of this product adopts multi-layer composite sealing components. Every motor undergoes continuous pressure retention leak testing before leaving the factory, which prevents oil seepage during long-term full-load continuous operation. It is suitable for production lines with strict cleanliness requirements in food processing and fine chemical industries.
Integrated Optimized Structure for Noise & Heat Control
Our precision-ground helical gears greatly reduce meshing resonance, cutting operating noise by 10% compared with standard models. The extended and widened heat dissipation cavity optimizes the air duct, lowering temperature rise under full load by over 10% to support round-the-clock non-stop mass production.
IP55 Industrial Protection & Cost-Effective High Load Capacity
The reducer features IP55 dustproof and splash-proof protection, enabling stable long-term operation in harsh workshops filled with dust and cooling water sprays. Following the upgraded mechanical structure, its maximum load capacity has increased by over 10%. It boasts a lower procurement cost for the same torque specifications and serves as the primary power unit for heavy-duty automated equipment.
Q:Can internal spare parts be interchanged between 90mm and 100mm flange versions of this 120W motor?
A:Core transmission parts such as gears and windings are universal, but flange base and housing sizes differ. The two flange models cannot be directly replaced, select according to your equipment mounting base.
Q:Can the peak torque 31Nm be used for 24-hour full-load continuous assembly lines?
A:31Nm is short-time impact torque only for intermittent equipment. For all-day continuous production, keep actual load below 60% of peak torque to slow gear abrasion and winding overheating aging.
Q:What copper wire gauge is needed when wiring multiple 120W motors in parallel with max 1.9A current?
A:0.75mm² copper wire works for single motor wiring within 5 meters. Use 1.0mm² copper wire if wiring distance exceeds 10 meters or 3+ motors are connected in parallel, to avoid power loss from voltage drop.
