RKIB11-3P-690xH | Torque Motors

Drawing

RKIB11-3P-690xH drawing — outer diameters 795 f8, 778／761／690, centring diameters D_STA／D_SA H7, primary part height H_P, secondary part height H_S, including distance between housing and cooling inlet／outlet (H_P0／H_P1), axial and right-angle cable screw heights (H_P2／H_P3), 3×45° chamfer, 5／12.5／28 detail dimensions, and secondary part inner diameter D_SN. Magnet configuration variants: R20 and R22 share the same axial cable outlet drawing (148／58.4, 2×4G10), V22 has a separate axial cable outlet drawing (148／58.4, 2×4G10).

Description

RKI and RKIB are internal running permanent-magnet synchronous torque motors with a built-in rotor. The stator is a water-cooled, fully encapsulated laminated core structure. The permanent magnets of the RKIB rotor are integrated into the laminated stack, which provides the magnetic circuit. The magnet configuration variants R20, R22 and V22 correspond to different cost-effectiveness ratios and characteristics. The RKIB11-3P-690xH is divided by active height into 690×50 through 690×175, and is presented in the catalogue as two data-table groups: Part 1 (690×50／75／100／125) and Part 2 (690×150／175). In the type designation, D×H represents "effective air-gap diameter × active height" (in mm).

Part 1 (sizes 690×50／75／100／125) — Geometric Data

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).
