6.2 Installation requirements
The mounting instructions in the following chapters are recommendations.
The spindle manufacturer can specify different actions, and tools and resources needed for
mounting.
Tools and resources needed for mounting are not included in the scope of delivery. The
spindle manufacturer is responsible for their provision.
To mount/dismantle the motor parts, ensure the following ambient conditions:
● A draught-free room
● Technically dust-free and dry environment. The permissible relative air humidity lies
within the range 5% to 85%.
● The personal protection equipment required is specified in the appropriate work stages.
Danger of damage to the rotor banding of a synchronous motor
APM rotors have a banding (composite fiber) around the external diameter of the rotor
that must not be damaged.
• Keep the protective film until mounting the rotor.
• Remove the protective film only for balancing or immediately before mounting.
• Check the banding for damage before mounting.
• Mount the APM rotor centered in the spindle box using a mounting device.
• Use an assembly film.
Mechanical machining of the motor in the asynchronous version
Note
Mechanical machining of the rotor in the synchrono
us version by the customer is not
Before shrink-fitting, the inner diameter must be machined to the shrinkage dimension
according to the specifications in the respective dimension sheet.
Shrink-fitting the rotor core generally causes stresses in the spindle shaft. These stresses
cause deformations. For this reason, we recommend re-machining the shaft sections that
are important for the function, e.g. bearing seats, together with the external diameter of the
rotor core.
The shrink-fit rotor core must be machined to the external diameter specified in the
respective dimension sheet.
We recommend machining by grinding.
