RKIB5-3P-384xH | Torque Motors

Drawing

RKIB5-3P-384xH drawing — outer diameter 485 f8, centring diameters 468／453／384, and D_STA／D_SA (H7); primary part height H_P, secondary part height H_S, including the housing and cooling inlet/outlet distances (H_P0／H_P1), the axial and right-angle cable screw heights (H_P2／H_P3, including 10), air-gap annotations 2,5 and 1,5, 20／15, secondary part inner diameter D_SN, and the primary／secondary part threads (TS_P×TD_P, n_P×TP_P, TS_S×TD_S, n_S×TP_S). Magnet configurations R20／R22 and V22, axial cable outlet 2×4G10 (cable outlet spacing 135／55,5).

Description

RKI and RKIB are internal running permanent-magnet synchronous torque motors with a built-in secondary part. The primary part is a fully encapsulated, water-cooled laminated iron core. The secondary part's permanent magnets are integrated into the lamination stack, which provides the magnetic return path. The magnet configuration variants R20, V22 and R22 correspond to different cost-effectiveness ratios and attraction characteristics. The RKIB5-3P-384xH is divided by active height from 384×50 to 384×175, and split by size subset into Part 1 (384×50 to 384×125) and Part 2 (384×150 to 384×175).

Part 1 (sizes 384×50 to 384×125)

Notes

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