Assembly of mount and coupling
A motor can be attached to all Drive Units via mount and coupling.
The mount secures the motor to the Drive Unit and serves as a closed housing for the coupling.
The coupling transmits the motor drive torque to the Drive Unit's drive shaft without distortive stresses.
Our standard couplings compensate for the system's thermal expansion.

Construction of timing belt side drive
The motors of all Drive Units can be attached using a timing belt side drive.
This makes the overall length shorter than when attaching the motor with a mount and coupling.
The space-saving, closed pulley housing serves as protection for the belt and as a motor bracket.
In addition, various gear ratios are also available (depending on size):
- i = 1
- i = 2
The timing belt side drive can be mounted in four different directions:
- bottom, top (RV01 and RV02)
- left, right (RV03 and RV04)

Application-related notes
AOK and AGK Drive Units are designed for drive tasks only and can only absorb axial forces.
When using a Drive Unit, always make sure to include adequate, separate linear guides that can handle the structure being moved as well as the resulting reaction forces and torques.
This results in a linear motion unit (e.g. table top) that can be moved automatically thanks to an AOK or AGK Drive Unit.
Examples
Example of basic motion unit structure with table top and AOK Drive Unit
In this example, two separate linear guides, each with two Runner Blocks, absorb forces and torques so that when moving the structure only axial forces act on the Drive Unit (here AGK).
Follow the assembly instructions and installation tolerances in the "Installation" section.
