9.9 Attachment
9.9.1 Stators with cooling jacket (without housing)
The stator is attached by screwed connections to one of the two front faces of
the stator. Under no circumstances should both front faces be screwed down.
The diameters of the front faces of the stator may vary depending on the se‐
lected stator type, this facilitating assembly (see fig. 9-19 "Example: Stator
assembly" on page 280 ).
When planning the mounting process, refer to the selected output direction of
the power cable as well as the details of the dimension sheets referring to
●
the quantity and type of the mounting thread,
● the tightening torque,
● the screw-in depth.

● The screw length required depends on the machine con‐
struction.
● Under no circumstances should both stator front faces be
screwed down.
● The screwed connections have to be able to take up both
the force due to the weight of the motor and the forces act‐
ing during operation.
● Comply with the minimum screw-in depth for screwed con‐
nections on the stator MST.
● For more information on assembly of motors with cooling
jacket, please refer to chapter 12.4 "Mechanical assembly"
