NettetStandard motors are rated for continuous duty (24/7) at their rated load and maximum ambient temperature. Specialized motors can be designed for “short-time” requirements where intermittent duty is all that's needed. These motors can carry a short-time rating from 5 minutes to 60 minutes. The NEMA definition for NettetThe full load current of a motor is the current drawn by it while operating at full load and rated voltage. It is a measured value and can also be calculated using formulae. The full load current may vary upon the applied voltage. Also, the rated full load current (FLC) is the one specified by the manufacturer while tested at ideal conditions.
