●
The screw length required depends on the machine con‐
struction.
●
The screwed connections have to be able to take up both
the force due to the weight of the motor and the forces act‐
ing during operation.
●
Comply with the minimum screw-in depth for screwed con‐
nections on the rotor MRT.
●
The rotor may not be heated.

A motor encoder is required for measuring the position and the velocity. Par‐
ticularly high requirements are imposed on the motor encoder and its me‐
chanical connection.
The motor encoder is not included in the scope of delivery of MBT
motors. Suitable motor encoders have to be selected by the ma‐
chine manufacturer based on the requirements of your application
or machinery.
In case of questions on technical compatibility of the motor en‐
coder with Rexroth controllers, please contact the Rexroth cus‐
tomer support.
If the position of the rotor to the stator has to be determined immediately after
power-up or a malfunction (pole position recognition), an absolute encoder
system is recommended.
The accuracy of the motors is generally defined by the
●
mechanical rigidity of the overall system.
