Duty
|
The service of an electrical motor defines the load duration and sequence to which the motor is subjected. Nicolini & C. motors can operate for a continuous service, indicated with S1, unless otherwise required. The continuous service consists in subjecting the motor to a constant load with enough duration to guarantee the achievement of a thermal balance. |
