Synchronous Servo Geared Motors

EZ Inline and Offset Geared Motors

STOBER inline and offset geared motors are available as planetary geared motors and as helical or offset helical geared motors. Offset helical geared motors have a parallel input and output and a large shaft-centre distance. All other geared motors are of coaxial design. All drive units are provided with high-quality helical gearing for unrivalled smoothness of running and backlash stability. Backlash down to < 1 arcmin. Super compact synchronous servo motor EZ for high dynamic.
