Rexroth IndraDyn H Type Codes of IndraDyn H Motors 6-3
DOK-MOTOR*-MBS-H******-PR02-EN-P
Type Code for Rotor “MRS”
1. Product Group
MRS is the rotor designation of a high-speed synchronous kit motor of
the IndraDyn H series.
2. Motor Frame Size
The motor frame size is derived from stator dimensions and represents
different power ranges.
3. Motor Frame Length
Within a series, the graduation of increasing motor frame length is
indicated by ID letters in alphabetic order. The higher the motor frame
length, the higher the torque.
Frame lengths are, for example, A, B, C, D and E.
4. Shape/mechanical construction
Specifies the type of how the rotor is bored.
1N = smooth rotor drilling,
2N = step interference fit.
For further information to design please refer to the chapter 9.6 “Design
and assembly principle of rotor/spindle shaft”.
5. Rotor - internal diameter
Represents the internal diameter of the rotor in millimeter (mm).
6. Other designs
Reserved for optional types. You can find a short description in the
appropriate type code, mechanical details in the respective dimension
sheet.
