Stober PK - Dimensional Drawings; EZ2 - EZ3 Motors (One Cable Solution)

11.4 Dimensional drawings
In this chapter, you can find the dimensions of the motors.
Dimensions can exceed the specifications of ISO 2768-mK due to casting tolerances or accumulation of indi-
vidual tolerances.
We reserve the right to make dimensional changes due to ongoing technical development.
You can download 3D models of our standard drives at https://configurator.stoeber.de/en-US/
