P-EZ planetary servo geared motors

P precision planetary gear unit with EZ STOBER servo motor. In the power range 0.25 – 31.0 kW. Gear ratio range 3:1 – 100:1. Torques max. 10 – 3,450 Nm. Rotational clearance 1.0 – 8.0 arcmin. Efficiency 95 – 97%. Optionally with encoder, resolver, reduced backlash, two brakes, fan, single-cable with EnDat 3.0, with rack and pinion, with SC6 / SI6 / SD6 servo drive.
P-EZ planetary servo geared motors
Compact and very dynamic thanks to direct mounting of the gearbox on the servo motor without an adapter or clutch.
