The Bosch Rexroth IndraDyn S MSK synchronous servo motor series is built around a wide performance spectrum with fine size gradation, using high torque density to support compact machine designs and delivering maximum torque capability up to 631 Nm within the series.
| Type code position / field | What it means | How it appears in the code | Code Values |
|---|---|---|---|
| 1) Product family | Motor family identifier | MSK |
MSK = IndraDyn S synchronous servomotor series |
| 2) Frame size | Motor size class that sets key mechanical dimensions |
|
Common frame sizes include
(availability depends on generation) |
| 3) Frame length | Length variant within the frame size |
|
Letter codes such as A/B/C/D/E (varies by frame size) |
| 4) Winding code | Electrical winding variant (ties to rated speed/torque data) | -0200-, -0300-, -0450-, -0600-, etc. |
4-digit winding codes; some variants may indicate special parameterization (e.g., field-weakening-related variants in certain series) |
| 5) Cooling type | How the motor is cooled |
|
(series-dependent options may exist) |
| 6) Encoder type | Encoder family + singleturn/multiturn | -S1-, -M1-, -S2-, -M2-, -S3-, -M3- |
“x1/x2/x3” denotes encoder technology/variant family |
| 7) Connection / connector orientation | Power + feedback connection style/orientation | …-U…, …-A…, …-B… (as part of the block after encoder) |
Often seen:
(other orientation/terminal-box variants exist in the series) |
| 8) Shaft version | Output shaft style | Appears right after the connection letter: …-UG…, …-AP…, etc. |
Common shaft letters:
other shaft styles exist in the series |
| 9) Holding brake code | Whether a holding brake is installed (and brake variant class) | Single digit after shaft letter: …G0…, …G2…, …P1… |
|
|
10) Variant / design suffix (4 chars) |
Standard vs special versions / options | Final 4 characters, e.g. NNNN, NNAN, etc. |
NNNN commonly used for “standard”; other suffix patterns indicate special options (examples include Ex variants, increased concentricity/runout classes, and other mechanical/electrical options depending on series) |
