Note

The examples provided below are not necessarily complete nor are they suitable for all applications.

Note that the rotor and stator are secured on one side on the machine construction. Depending on the machine construction, the stator can be secured on the same side as the rotor or on the opposite side.

Table 6- 4	Explanations for the following installation examples
	Image title	Description
Rotary table with torque motor		The construction shown is ideal for precision applications and
with integrated cooling		tilting tables with strong machining forces. The phase-angle
		encoder is integrated in the bearing.
Rotary table with torque motor		The construction shown is ideal for precision applications,
with cooling jacket		dividing units, applications with holding operation, and tilting
		tables with an integrated brake. It is compact and, therefore,
		easy to integrate.
Part-turn actuator with torque		The construction shown is ideal for robots, robot systems, and
motor with integrated cooling		tool changers. The phase-angle encoder is sufficiently decoupled
		from the heat source (motor winding).
Installing a torque motor with		1.:
integrated cooling on the shaft		The stator and rotor are installed via transportation locks on
extension of a part-turn actuator		flange B (flange with cable outlet) with the delivery of the motor.
		The spacer film can be found between the stator and rotor.
		The transportation locks are loosened and the rotor is attached
		to the shaft extension with its mount. In this case, observe the
		specified torques and mounting technology specifications.
		2.:
		The stator is positioned and screwed into its mount. In this case,
		observe the specified torques and mounting technology
		specifications. At this point, the transportation locks and spacer
		film can be removed.
Part-turn actuator with torque		The construction shown is ideal for moderate load forces and
motor with cooling jacket		medium precision requirements (e.g. woodworking, packaging
		systems, tool changers). For roller drives, this construction is
		only suitable for short axes with low deflection.
Roller drive with low shaft		The construction shown is ideal for roller drives with high
deflection with torque motor with		concentricity requirements and low positioning accuracy. A rotary
integrated cooling		encoder with a moderate angular resolution is sufficient here.
		The encoder must be decoupled from the thermal expansion of
		the shaft by means of a suitable interface.
