RIB11-3P-120xH | Torque Motors

Drawing

RIB11-3P-120xH drawing — stator (primary part) height H_P, rotor (secondary part) height H_S, outer diameter 185, inner diameter 90 H8. Includes the stator/rotor thread hole distribution (TS×TD, n×TP) and the cable outlet position.

Description

RIB is an internal-running permanent-magnet synchronous torque motor. The stator is a water-cooled, laminated, fully encapsulated iron core; the rotor is a steel ring with permanent magnets bonded radially onto the steel ring, which provides the magnetic return path. The rotor can be centred from either side of the inner diameter and fixed at the end face. The RIB11-3P-120xH series is divided by active height into 6 sizes from 120×25 to 120×150.

Notes

Tolerance range ±10%. In the type designation, D×H represents "effective air-gap diameter × active height" (unit: mm).
