Note
: The figures above illustrate the typical internal and external arrangement of the motor main components,
and its purpose is to make the disassembly and reassembly operations easier to understand. Some details of the
motor (for example the external fan, the bearing clamps etc) may have a different technical solution, or there may
be additional accessories, which, however, do not cause any important changes in the sequence of the
disassembly and assembly operations.
Always refer to the specific documentation of the order for further details and particulars.
If in doubt, contact the manufacturer or an
Service organisation.
