Asynchronous Motors Ver. 0002 AM - 25
AM.9.1 VENTILATION
SPM series motors carry an electric fan that generates a constant air flow regardless of the
motor speed. That way, proper cooling is assured for any working condition. The motors can
run at their rated current or peak current at low speeds without losing their specifications.
The electric fan must be turned on before powering the motor and must
never be stopped while the machine is on.
Important:
Make sure that the air taken in by the fan is always fresh, clean and dry. For motors
installed inside the structure of another machine and/or protected by panels or other type
of covers, it is absolutely essential that the air comes in from the atmosphere through the
corresponding conduit and channel system and that it is sent back out through the
ventilation openings. The fresh air intake and the hot air outlet must be as far apart from
each other as possible. In any case, make sure that the hot air (going out) and the fresh
air (coming in) are not mixed.
AM.9.2 MOUNTING OPTIONS
These motors may be supplied as to be mounted horizontally B3/B5 (feet/flange) or vertically
types: V1/V5 or V3/V6. The motor nomenclature indicates the mounting type. See appendix C.
The motor must be fitted onto a flat, solid and sturdy surface. If the motor suffers excessive
vibrations, it is often due to the weakness of the base supporting it.
When foot-mounted, the supports are located on the base of the motor itself and its
dimensions and supports are standard. The motor must be mounted onto a perfectly flat
surface in order to avoid deforming and breaking the protections which could cause contact
between the rotor and the stator. If necessary, step up the motor support until perfectly flat and
uniform motor mounting is achieved. Any element used to step it up must be made of the
proper material and not smaller, in dimensions, than the motor foot itself.
Secure the motor with the right size bolts, nuts and self-locking washers. Make sure that the
tools used to secure the motor do not interfere with its operation or damage it.
