RIB17-3P-168xH | Torque Motors

Drawing

RIB17-3P-168xH drawing — stator (primary part) height H_P, rotor (secondary part) height H_S, outer diameter 230⁻⁰·¹², inner diameter 140 H8. Annotations include the stator/rotor threaded-hole patterns (TS×TD, n×TP) and the cable outlet position.

Description

RIB is an internal-running permanent-magnet synchronous torque motor. The primary part (stator) is a fully encapsulated, water-cooled laminated iron core; the secondary part (rotor) is a steel ring with permanent magnets bonded radially to it, the steel ring providing the magnetic return path. The rotor can be centered from either side of the inner diameter and is fixed at the end face. The RIB17-3P-168xH series is divided by active height into 7 sizes, from 168×25 to 168×175.

Notes

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