The basis for every order for a Rexroth product is the type code. All available
motor variants are clearly described by the type code. The individual type
code positions (short text column) and their meaning are described below.
Have your Bosch Rexroth sales partner check the availability of
individual options before placing an order.
Example: MSK-...
MSK three-digit Rexroth specific designation of a servo motors series
Example: MSK050-...
The motor size determines important mechanical motor dimensions and is
proportional to the power rating.
Example: MSK050B-...
Within a series, increasing motor frame length is graded by means of code
letters in alphabetical order. Frame lengths are e.g. B, C, D and E.
Example: MSK050B-0300-...
The four-digit number sequence indicates the rated speed which applies to
the respective winding variant.
Example: MSK050B-0300-NN-...

Cooling type
Example: MSK050B-0300-NN-S1-...
MSK motors are equipped with built-in encoder systems. For controlling the
motor speed and/or positioning of the motor, the drive control unit requires
the current motor position.
Example: MSK050B-0300-NN-S1-U-...
