ER series helical gear units: high efficiency and wide range of gear unit ratios
The figure shows gearmotors with helical gear unitsHelical gear units are the "hidden classics" in our gear unit portfolio:
6 single-stage and 15 two- and three-stage frame sizes cover a torque range from 50 to 18 000 Nm. This gear unit series is also far ahead in terms of gear unit ratios: from i = 1.30 to i = 289.74, in double gear units even i = 27 001. Torque ratings and gear unit ratios this finely stepped are hard to find in the market.
The demand for high output speeds or low weight is met by the R gear units as well, of course. Always with a high level of
efficiency, our helical gear units offer an optimum ratio between torque output and installation space.
This means: a helical gearunit almost always fits your application.
Only half the solution without a motor? Then use our modular concept and combine the gear units of the R series with an AC motor to a compact gearmotor or with a servomotor to a servo motor of your choice. Or simply choose the separate AC motor or serve motor that meets your requirements.
