SEW W Series SPIROPLAN® Right Angle Gearmotor
The SEW W Series SPIROPLAN® Right Angle Gearmotor offers exceptional advantages tailored for light to medium-duty industrial scenarios, standing out with its compact design and reliable performance. Its core merit lies in the unique SPIROPLAN® gearing, featuring a steel-on-steel material combination and specialized tooth meshing that enables wear-free operation, ultra-low noise, and minimized friction losses—boosting mechanical efficiency up to 94% and outperforming traditional worm gear reducers. The rugged aluminum housing reduces overall weight significantly while ensuring structural durability, making it ideal for weight-sensitive setups.
Lifetime lubrication eliminates routine maintenance needs, extending service life and cutting operational costs, while sizes W10, W20, and W30 support flexible mounting in any orientation without adjusting lubricant levels, thanks to consistent footprint and shaft heights. Modular design offers diverse configurations, including foot/flange mounting, solid/hollow shafts, and compatibility with AC or servo motors, enhancing adaptability. Covering gear ratios of 3.2 to 75 and output torques from 12 to 180 Nm, it excels in space-constrained and noise-sensitive applications like packaging conveyors, laboratory mixers, printing equipment, and food/beverage logistics. It also suits metering pumps and small material handling conveyors, delivering cost-effectiveness and stable performance for fractional horsepower tasks. (400 words)
