Servomotor gear-motor S_D/ S_TA series

wormhelical gearright angle

Product overview
Worm gear units (worm geared motors) provide high gear reduction in a compact, angular arrangement suitable for low-speed applications such as mixers and conveyor drives. The S-series modular design covers sizes S0–S4 and allows combination with various motor adapters or free input shafts to match installation requirements.

Applications and motor adapters

• Possible motor adapters for IEC motors
• NEMA motors
• Servo motors

Highlights

• Multiple housing and output-shaft versions
• Double-sided output shaft option
• Reinforced bearings
• Improved sealing for reduced leakage and noise
