Integrated Thickened 100mm Frame Size
Unified 140W Micro Gear Motor with an extra-wide and thickened size of 100×100mm, an overall length of 280mm and a self-weight of 6.4kg. Its integrally die-cast housing delivers greatly enhanced rigidity. Both the motor input shaft and reduction output shaft adopt a unified 15mm solid thick shaft, offering maximum bending resistance and impact resistance under heavy loads.
Full-Range High-Current Drive Matching for High Power
The Micro Gear Motor is equipped with a high-power winding rated at 140W, compatible with global single-phase AC power of 50Hz/60Hz. Its operating current ranges from 0.46A to 2.2A, and it is matched with large-capacity starting capacitors from 8uF to 32uF. It can withstand the instantaneous startup impact of heavy materials with sufficient current margin to avoid stalling.
Wide Ratio Range with Ultra-High Torque Output
This AC gear reducer features a full range of reduction ratios covering all gear stages from 1:3 to 1:300, with an output torque ranging from 2.46 to 32.5 Nm, more than double the maximum torque of medium and low-power models. It is compatible with high-intensity transmission equipment such as heavy-load conveyors, heavy-duty turnover machines, and lifting devices.
High-Pressure Air Tightness Tested Leak-Proof Construction
The 140w Micro Gear Motor is equipped with multiple high-temperature and oil-resistant sealing rings built into its gearbox. Every finished unit undergoes high-pressure airtight immersion leak testing before leaving the factory, eliminating the risk of oil leakage during long-term continuous full-load operation. It fully complies with the clean production standards for food, chemical and dust-free workshops.
Precision Ground Gear & Surround Cooling Dual Optimization
The 140w Gear Motor adopts high-precision ground helical gears, which greatly reduce meshing vibration and cut operating noise by 10% compared with general reducers on the market. Its extended and widened body reserves surrounding heat dissipation air ducts, lowering temperature rise under full load by over 10% and enabling continuous heavy-duty operation 7×24 hours a day.
IP55 Industrial Protection & Cost-Effective Heavy Load Capacity
The speed reducer features IP55 dustproof and splash-proof protection, enabling stable long-term operation in harsh production environments with accumulated dust and cold water spraying. Its reinforced mechanical structure boosts the ultimate load capacity by over 10%. It offers superior procurement cost advantages within the same torque class and serves as the primary power source for heavy-duty automated equipment.
Q:Does the 6.4kg motor body need extra load-bearing brackets for vertical top hoisting installation?
A:The thickened 100mm flange provides sufficient rigidity without extra reinforcement for standard shaft extension length. Independent support stand is required if the output shaft stretches over 400mm to share radial tension and prevent shaft deformation.
Q:What wire gauge should we use for multiple synchronized 140W motors with max 2.2A current?
A:0.75mm² copper wire works for single motor wiring within 5 meters. For wiring over 10 meters or two & more motors connected in parallel, 1.0mm² or thicker copper wire is mandatory to avoid insufficient power caused by line voltage drop.
Q:How often should we maintain the gears if the motor runs long-term in oily & dusty workshops?
A:Routine lubrication maintenance every 6 months under standard working conditions; shorten the cycle to 3 months for heavy dust & oil pollution environments. Clean cooling ducts and replenish special gear grease to reduce dry abrasion of gear teeth.
