6.1 Type codes
6.1.1 General
The type code describes the available motor variants. The type code is the
basis for selecting and ordering products from Bosch Rexroth. This applies to
new products as well as to spare parts and repairs.
The torque motors MBT of Rexroth consist of the components "stator" and
"rotor". The type code is divided into “Type code stator MST..." and “Type
code rotor MRT...".
The following description gives an overview of the separate columns of the
type code ("abbrev. column") and its meaning. The sections below describe
the type codes for specific frame sizes.
6.1.2 Type code stator MST
Product Example: MST□□□□-□□□□-□□-□□□□-□□□□
MST is the designation of the stator of a torque motor of the MBT series.
Frame size Example: MST360□-□□□□-□□-□□□□-□□□□
The frame size is derived from the mechanical motor dimensions and repre‐
sents different power ranges.
Frame length Example: MST360B-□□□□-□□-□□□□-□□□□
Within a series, increasing stator frame length is graded by means of code
letters. The torque increases with increasing frame length while the nominal
velocity decreases. Frame lengths are e.g. A, B, C, ...
Winding Example: MST360B-0018-□□-□□□□-□□□□
The four-digit numerical sequence indicates the rated speed which applies to
the respective winding variant.
Example: Winding "0018" stands for a rated velocity n
N
= 180 min

. The ref‐
erence value is a DC bus voltage of 540 V

Cooling type Example: MST360B-0018-F□-□□□□-□□□□
Option Design Detail
F Water cooling
Default cooling type.
Operation of motors with cooling type "F" without
water cooling is permitted under certain condi‐
tions. In this case, however, reduced performance
data is generally applicable. For more information,
please refer to chapter 9.7.8 "Operation without
liquid cooling" on page 276 .
N Self-cooling Only applicable to MST130 / 450 / 530.
