WebThe longer the motor cable or if the cable is screened instead of unscreened, the higher these charging currents. The motor cable length and type has more affect at low powers and much less at higher powers. For all powers the ambient temper-ature, current rating and derating curves are given for the worst case situation (150m screened/ WebAnother common word for derating, in the context of computers and CPUs, is underclocking. As opposed to overclocking, where you run a cpu at a higher than rated speed, underclocking (aka derating) runs it at a lower speed, allowing for less heat and longer life. Mainly used when modders want to remove noisy fans.

However, derating particular motors or devices, particularly on a car, reduce the speed of the vehicle or overall engine performance. Derating is a method also used to prevent the engine from overheating. WebThe efficiency of a motor is one factor that affects the full load current rating of a motor and therefore has an impact on the ambient temperature rating of the frequency converter for use with that motor when operating at full load. scansnap s510 software windows 11
