Image title	Description
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.
