SEW K Series Helical Bevel Gearmotor low voltage
SEW K Series Helical Bevel Gearmotor (Low Voltage)
The SEW K Series Helical Bevel Gearmotor (Low Voltage) offers exceptional advantages, making it a versatile choice for low-voltage industrial drive scenarios requiring right-angle power transmission. Its core merit lies in precision helical-bevel gearing, which enables smooth torque delivery, ultra-low operating noise, and outstanding load-bearing capacity—outperforming standard gearmotors in both light and medium-duty tasks. The robust construction, paired with high-quality materials, ensures durability and stable operation in harsh environments with dust, vibration, or moderate temperature variations.
Adhering to global low-voltage safety standards, it guarantees safe operation in voltage-constrained sites, reducing potential electrical hazards. Compatible with S and S..7p series gear units (sizes 37 to 97), it boasts broad configuration flexibility, supporting compound gear setups for ultra-high gear ratios up to 33,818 to meet diverse speed requirements. Equipped with AM motor adapters, it accommodates motor power ranging from 0.12 to 30 kW, facilitating seamless integration into existing systems. Widely applied in conveyors, mixers, material handling equipment, packaging machinery, and textile lines, it excels where space efficiency and reliable right-angle drive are critical. Backed by SEW’s global service network, it minimizes maintenance needs, cuts operational costs, and balances adaptability, reliability, and cost-effectiveness for low-voltage industrial demands.
