Rexroth IndraDyn T Type Codes 6-1
DOK-MOTOR*-MBT********-PR03-EN-P
6 Type Codes
The type code describes the motor variants that are supplied; it is the
basis for selecting and ordering products from Bosch Rexroth. This
applies to both new products as well as spare parts and repairs.
Rexroth IndraDyn T torque motors consist of the components “Stator” and
“Rotor”. The type code is divided into “type code for Stator MST...” and
“type code for Rotor MRT...”.
The following description gives an overview of the individual positions of
the type code (“Abbrev. column”) and their meanings. You can find the
type code for a particular unit in the following chapter.
Type Codes for Rotor MRT
1. Product Group
MRT is the designation of an IndraDyn T rotor unit.
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.
Frame lengths are, for example, A, B, C and D.
4. Shape / Mechanical Construction
3N represents the fastening of the rotor by bolts.
5. Rotor - Internal Diameter
Indicates the internal diameter of the rotor in millimeters (mm).
6. Other designs
Reserved for optional types. You can find a short description in the
appropriate type code; mechanical details are in the corresponding
dimension sheet.
