Cyclo Gearmotor with Torque Limiter Sumitomo Drive Technologies

The Sumitomo CYCLO Gearmotor is unsurpassed by any other inline drive available in the market today. The CYCLO unique cycloidal design has advantages superior to speed reducers using common involute gears. CYCLO components operate in compression, not in shear. Unlike gear teeth with limited contact points, a CYCLO has 30 % of its reduction components in contact at all times. CYCLO speed reducers and gearmotors provide exceptional performance, reliability and long life in the most severe applications

The Cyclo gearmotor has particularly high efficiencies over a wide range of reduction ratios, which frequently permits the use of reduced input power requirements (smaller HP motor) without sacrificing output shaft torque. The selection procedures in this catalog will guide you in choosing the most efficient gearmotor for your application.

CYCLO’s Gearmotor  unique ‘gearless’ design is distinctly superior to common involute gear speed reducers, operating in compression rather than shear, resulting in:

  • Minimal vibration
  • 500% Momentary shock-load capacity
  • Low backlash and extended operational life

Detect overloads instantaneously with installed torque limiter.
