General arrangement
Note
: The sketch illustrates 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 organization.
