Basic design; compactness and economy. IEC standardized motor. High, reliable and tested performances (Ni bronze); optimization of worm gear pair performances (ZI involute profile and adequately conjugate worm wheel profile) Rigid and precise cast iron single-piece housing with motor mounting integral flange. Generous internal space between train of gears and housing. 

Features• Mounting with lower integral feet and B14 flanges on 2 faces integral on the housing• Rigid and precise cast iron monobloc housing• Worm wheels made of nickel bronze with controlled phosphor contentto achieve improved performance, a higher load capacity, greater reliability and wearresistance• Generous internal space between train of gears and housing• Tapered roller bearings on worm shaft• Motor mounting flange integral to the housing• Higher worm efficiencyBenefits• Longer life and lower power consumption• Interchangeability with major manufacturers• High performance and greater reliability• Smooth and quiet running

g500-H + m550-V helical gearmotors

These IE6 helical gearmotors with maximum efficiency in a compact design focus on sustainability and future energy efficiency requirements. The compact drive units can realize very high starting torques during sensorless operation on the drive. The drives can be used worldwide and comply with most approvals. The highest energy efficiency IE6 (Grade 1 for China) is as compact as an IE3 drive solution.

Thanks to the helical gearbox, they have high permissible radial forces, closely stepped ratios and low backlash.

Highlights

• Very high energy efficiency IE6 according to IEC TS 60034-30-2 and Grade 1 according to GB30253-2024
• Starting torque up to 300 % from standstill
• Maximum reduction of the energy demand and thus the CO2 emission during operation
• Enables regional or market-specific energy efficiency support programs
• Can be used universally due to the market-oriented modular system
• Optimized for sensorless operation with the VFDs i510/i550 cabinet, i550 protec and i550/i650 motec
