The Siemens Drive Technologies Division is supplementing its Motox geared motors with a range of worm gears featuring high efficiency and an extensive transmission range; they are particularly suitable for conveyor systems. The single-stage worm geared motor of the S range is available in the three frame sizes S08, S18 and S28, in a torque range from 18 to 80 Nm and in a power range from 0.12 to 0.75 kW.
The gear and motor components of the S range are available in a versatile modular system, and can be used for all mounting positions. The input shaft is available either solid or hollow. The use of high-grade materials, such as a substantial nickel proportion in the bronze worm gears, allows high rated gear torques up to 80 Nm and high transmission ratios of up to 100 in a single stage. The worm shafts are also case-hardened and ground, which makes running quieter. A strong radial force is achieved by high-grade roller bearings and greater distances between bearings. The tooth root security of the Cavex concave-profile teeth allows high load peaks. The gears are maintenance-free due to lubrication-for-life with synthetic oil, as well as high-grade bearings and seals.
