1 Introduction
1.1 Fields of application
Typical fields of application of these motors are direct drives, e.g., in rotary
tables, swivel axes of machining centers, printing units as well as grinding
machines. But they also provide new solutions for innovative machine con‐
struction where robots, plastics machines, woodworking machines, lathes
and special machines are concerned. These motors have the following es‐
sential advantages:
● Maximum torques of up to 13,800 Nm
● Full torque already at standstill
● Extreme overload capability
● Best synchronous operation
● Liquid cooling with thermal encapulation
● Easy assembly

1.3 Motor layout
MBT synchronous torque motors are liquid-cooled kit motors which have
been optimized for high torques. They consist of a stator with three-phase
winding and a rotor with permanent magnets.
Descriptions of the individual modules:
●MBT: The assembly kit motor consists of the components stator (MST)
and rotor (MRT)
●MST: MBT motor stator
●MRT: MBT motor rotor
The stator consists of a laminated core with multipolar winding, a liquid cool‐
ing jacket and a connection cable. The option "cooling jacket in housing” for
stators contains a cooling jacket with a closed cooling circuit, a mounting
flange and an electrical connection via terminal box or device connector. The
cooling jacket is open at the rear and the rotor is connected to the machine
shaft and bearing.
Two characteristics are available for the motors
●Characteristics = MRTxx0 / MSTxx0
MBTxx0 motors are charaterized by a high continuous force and a very
high maximum force. The MBTxx0 motors represent classic high-torque
motors.
●Characteristics = MRTxx1 / MSTxx1
MBTxx1 motors are optimized regarding their synchronization character‐
istics. They have a force ripple that is about a factor of 3 lower than that
of the MBTxx0. The magnetic circuit was changed to achieve this. This
results in lower continuous and maximum forces for the same frame
size. These motors can be especially used for grinding applications, for
example.
Using Bosch Rexroth drive controllers, a comparable synchroni‐
zation quality can be achieved with both MBTxx0 and MBTxx1,
e.g. by activating the so-called "cogging torque compensation”.

2 Important instructions on use
2.1 Intended use
Rexroth products are designed and manufactured using the latest state-of-
the-art-technology. The products are tested prior to delivery to ensure opera‐
tional safety and reliability.
Bosch Rexroth, as the manufacturer, does not provide any war‐
ranty, assume any liability, or pay any damages for damage
caused by products not being used as intended. Any risks result‐
ing from the products not being used as intended are the sole re‐
sponsibility of the user.
Before using the products by Rexroth, the following condition precedent must
be fulfilled so as to ensure that they are used as intended:
● Personnel that in any way, shape or form uses our products must first
read and understand the relevant safety instructions and be familiar with
their intended use.
● Hardware products must be left in their original condition, i.e. no struc‐
tural changes may be made. Software products must not be decompiled
and their source code must not be changed.
● Damaged or defective products must not be installed or put into opera‐
tion.
● It must be ensured that products are installed and maintained in compli‐
ance with all regulations specified in the documentation.
Rexroth synchronous torque motors of the MBT series are designed to be
used as rotary main drive motors in machines.
For application-specific use of the motors, device types with different drive
power and different interfaces are available.
To control and monitor the motors, it may be necessary to connect additional
sensors and actuators.
The motors may only be used with the accessories and attach‐
ments specified in this documentation. Components that are not
explicitly specified must not be installed nor connected. The same
applies for cables and lines.
The device may only be operated in the explicitly specified config‐
urations and combination of components and in compliance with
the respective functional description of the software and firmware.
Before commissioning, every connected drive controller must be program‐
med according to the specified motor function for the specified application.
The motors may only be operated under the assembly, mounting and installa‐
tion conditions, in the normal position, and under the environmental condi‐
tions (temperature, degree of protection, humidity, EMC etc.) specified in this
documentation.
2.2 Non-intended use
Any use of motors outside of the fields of application mentioned above or un‐
der operating conditions and technical data other than those specified in this
documentation is considered as "non-intended use".
