RKIB11-3P-460xH | Torque Motors

Drawing

RKIB11-3P-460xH drawing — outer diameter 565 f8, centring diameters 548／531／460, secondary part thread pitch circle diameter D_STA, secondary part inner diameter D_SA H7／D_SN, primary part height H_P, secondary part height H_S, including distances from housing to cooling inlet/outlet (H_P0／H_P1) and heights of axial and right-angle cable screws (H_P2／H_P3). Magnet configurations R20／R22 (axial cable outlet 2×4G10) and V22 (axial cable outlet 2×4G10).

Description

RKI and RKIB are internal running permanent-magnet synchronous torque motors with a buried-magnet rotor. The primary part (stator) is a water-cooled, fully potted laminated iron core. The permanent magnets of the secondary part (rotor) are integrated into the lamination stack, which provides the magnetic return path. The magnet configuration variants R20, V22 and R22 correspond to different cost/efficiency ratios. In the PDF, RKIB11-3P-460xH is split into Part 1 (sizes 460×50 to 460×125) and Part 2 (sizes 460×150 to 460×175); each size includes the three magnet configurations R20／V22／R22.

Part 1 (sizes 460×50 to 460×125) — Geometric Data

Notes

Tolerance range ±10%. Each column is a "size × magnet configuration" combination. In the type designation, D×H denotes "effective air-gap diameter × active height" (in mm).
