RKI and RKIB Series Ordering Designation
RKI5 ---- 3P – 0230 – 050 – ZX.X- – P – O – M – C – A – 2.0 – RDDM – R22 – Y
Notes
The series and type codes of the RKI and RKIB series are selected by Schaeffler Industrial Drives based on the motor part and the effective air gap diameter. The table below describes each field of the ordering designation in turn.
| Field | Code | Description |
|---|---|---|
| Short designation, motor | RKI---- RKIB---- | RKI----: Series and type code RKIB----: Series and type code (selected by Schaeffler Industrial Drives based on motor part and effective air gap diameter) |
| Number of motor phases | 3P | 3-phase |
| Effective air gap diameter | 0230 | 4-digit code with units of mm; values below 1,000 are filled with leading zeroes (0230, 0298, 0384, 0460, 0690) |
| Active height | 050 | 3-digit code with units of mm; values below 100 are filled with leading zeroes (050, 075, 100, 125, 150, 175) |
