Selection Notes

This frame delivers 48 Nm standstill torque at 7.7 kW, more continuous torque and power than a smaller frame size in the same servo motor series, for axes that need more continuous torque at the same 2000 rpm nominal speed. Without a holding brake, the servo drive or an external brake must hold the axis at standstill; the same frame is also offered with an integrated brake for vertical or overhung-load axes. At 154.000 kgcm2 moment of inertia and a 125,000 Nm/rad shaft torsional stiffness, this motor suits higher-inertia loads than a smaller frame size in the series.
