6.1 Motor assembly 

Example 

With torque motor 1FW6090-0Px010-xxxx (active component length: 100 mm), the 

eccentricity is 0.2 mm, for example. 
The active radial force as a result of this centering error is, therefore:

NOTICE 

 

The attractive forces between the stator and rotor are approximately four to five times 

greater when the rotor is about to be inserted in the stator. 

 

 

Requirements of the installation device 

The installation device is designed to ensure that the stator and rotor are aligned centrically 

during the entire installation procedure. The active axial forces must be taken into account 

during installation. 
The installation device must be adapted by the customer in line with the machine 

construction. It must be sufficiently rigid so that it is not warped by the strong attractive 

forces between the stator and rotor. Radial forces must be taken into account when the 

installation device is dimensioned. 
The installation device must not have any loose parts. 

 

WARNING 

 

The stator and rotor must not come into contact with each other during centering and 

installation. 
The stator and rotor cannot be separated. The motor can no longer be used. This is why an 

installation device must be used.
