WebFeb 23, 2011 · DC motors do not have current inrush. Click to expand... And the DC inrush current should be the DC resistance divided into the applied voltage. Once the … When an electric motor, AC or DC, is first energized, the rotor is not moving, and a current equivalent to the stalled current will flow, reducing as the motor picks up speed and develops a back EMF to oppose the supply. AC induction motors behave as transformers with a shorted secondary until the rotor begins to move, while brushed motors present essentially the winding resistance. The duration of the starting transient is less if the mechanical load on the motor is re…

WebSep 13, 2024 · Inrush current is the high current drawn by a motor during its acceleration period. Inrush current begins when the motor is turned on and continues until it reaches rated speed. High inrush current decreases as the motor accelerates.
