Make sure that the motor is well-ventilated, that there is nothing to obstruct the free circulation of air,
and that no situation will arise that could block the regular heat dissipation.
The installation must also allow the performance of ordinary maintenance on the motor and, if sup-
plied, of the brake.
Avoid hitting on the motor shaft: bearings may be damaged.
In outdoor installations, protect the motor from direct sun ratiation and, if possible, from inclement weather.
Prior to tting anged motors onto gear units make sure that the key is retained safely into the key
seat. Coat thoroughly motor shaft with a suitable anti-seize product (Loctite 767 or equivalent) to pre-
vent fretting corrosion and facilitate removal of motor at a later time.
Every 6-12 months it may be recommended to remove the motor from the gear head, clean the shaft
area and re-apply the anti-seize product.
In order to avoid vibration once in operation, make sure the motor is secured tightly to mating gear-
box ange. Should the motor need to be painted, screen name plate as well as vented plug (if appli-
cable) and machined parts on beforehand.
After the installation of a brake motor is complete, unscrew and remove the lever that operates the
manual brake release, thus preventing any accidental operation of the same.
3.6 Balancing
The rotor shaft is dynamically balanced with half key tted. Assembly of external transmission unit
must be performed with adeaquate instruments after suitable balancing, avoiding knocks which could
damage the bearings.
Be especially careful not to operate the motor without having properly secured the key not being
used (motors with two shaft ends).
Adopt adequate measures to avoid accidental contact with exposed live or moving parts.
Avoid contact with the motor case, since the temperature under normal operating conditions
may exceed 50 °C.
3.7 Insulation test
Before start-up, or after long storage (or idle) periods, check insulation resistance to mass with
Megger at 500V DC.
The value measured at 25 °C for new windings in good condition should exceed 10 MΩ.
If this value is not reached, oven drying will be required to eliminate excess humidity.
