INSULATION CLASS AND HEATING
Usually the motors have a class F isolated windings. For the various types of insulation the maximum over temperature that will be admitted are related in the graphic. Warning: The maximum temperatures that are tolerated in the red zone are referred to the internal measurement of the electric motor. The external measurement therefore can’t be associated to the table.
OVERLOADS
It’s possible to overload the motors without damaging the windings. You must read and follow the indication in the related table.
Every period of overload must be follow with a period of functioning with a nominal power or inferior. This is necessary to restore the electric motor in normal condition.
The values and the nominal electric specs can differ during the overload.
Overloads coefficients – Single-phase electric motors
| WORKING TIME | PERMANENT | 1 Hour | 15 Min | 1 Min |
|---|---|---|---|---|
| Overload coeff. | 1 | 1,05 | 1,15 | 1,3 |
Overloads coefficients – Three-phase electric motors
| WORKING TIME | PERMANENT | 1 Hour | 15 Min | 1 Min |
|---|---|---|---|---|
| Overload coeff. | 1 | 1,07 | 1,2 | 1,5 |
SERVICE TYPE
The standard execution of our electric motors is S1, in the diagram you can find also others possibility of service.
