Service regime

Service regime is the graph of the speed, the torque or the power of charge, over time, when the variations of these quantities are repetitive and recurrent.  Although the regulatory standard lists ten types of service regimes,  at present three are addressed, with the continuous regime being the intermittent and the limited time regime (short duration).

The service regime is continuous when the load remains for a long time activated by the motor, enough that the regime temperature is reached. Loads of this type are ventilators, pumps and air conditioners among others and the duration of the work regime can be some hours or even days, being primarily the power of operation can be considered stable. The engine can be subjected to variable load, but periodically, which establishes constant charge cycles throughout the service period. The service regime is called intermittent when load variations occur, so that the motor alternates load time intervals with zero-speed rest intervals and zero load. In case the operating cycle is so low that the engine can not reach the regime temperature.
