2 Basic safety notes
2.1 Intended use
The STM was designed to rotate loads, workpieces and objects.
The STM may only be operated in combination with a controller.
The module is intended for installation in a machine. The re-
quirements of the applicable guidelines must be observed and
complied with.
The module may be used only in the context of its defined appli-
cation parameters.
Any other use or use exceeding that specified is an infringement
of use for intended purpose. The manufacturer bears no liability
for damage resulting from such use.
To use this module as intended, it is also essential to comply with
the manufacturer's specifications regarding commissioning, as-
sembly, operation and ambient conditions.
2.2 Environmental and operating conditions
The module may be used only in the context of its defined
application parameters (see chapter 5, page 17 and catalog).
Make sure that the module's range of application is outside
the explosive area.
Make sure that the environment is clean and the ambient
temperature corresponds to the specifications per the catalog.
Make sure that the environment is free from splash water and
vapors as well as from abrasion or processing dust. Excepted
are modules that are designed specially for contaminated
environments.

Figure 1 Components
The STM is a completely mounted, permanently excited synchro-
nous motor in a cylindrical housing with a center bore.
The STM has an integrated measuring system. A temperature
sensor is integrated in the motor winding.
The STM belongs to the category of torque motors. The
typical characteristics of a torque motor are its high torque, low
speeds and a strong rigidity.
The STM is used typically for rotating and pivoting of large
masses. The center bore can be used as a media feed-through.
The STM must be operated using a controller. The following op-
erating modes can be set:
•Torque-controlled
•Speed-controlled
•Position-controlled

5.1.2 Mechanical interfaces
The STM is mounted on a single Franke bearing. This bearing is
lubricated via one-time grease lubrication. Under normal operat-
ing conditions lubrication for 20.000 operating hours is sufficient.
The mechanical interfaces are shown on the drawing in chap-
ter 16 page 73.
