    starting current calculator for induction motor

    Determine the initial (inrush) current of motors given rated power, voltage, and type. Perfect in electrical design, protection settings, and motor control planning. A motor starting current calculator is an instrument to approximate the high inrush current that a motor may take when it is first started, which can be 5 to 7 times the full-load current. The calculation is essential in the process of selecting the right protection devices, designing electrical systems, and avoiding voltage drops and damage to equipment. The calculator makes it easy to estimate the starting current by simply entering the most relevant motor parameters such as power rating, voltage, and phase type. It is particularly useful to engineers and electricians dealing with motor control panels, soft starters, or power distribution systems.

    What is the Motor Starting Current?

    The Motor Starting Current Calculator comes in handy when one wants to estimate the inrush current that electric motors take during startup. Motors normally require multiple full-load current ratings of the motor during start-up up which may result in voltage drop and electrical stresses on the system unless properly considered. This calculator gives an accurate and fast estimation of the starting current by inserting the fundamental data about the motor power (in kW or HP), voltage, phase (single-phase or three-phase), and type of the motor (squirrel cage, slip ring, etc.). It is required reading for electrical engineers, technicians, and designers who must correctly size circuit breakers, fuses, contactors, and cables, or who must configure motor protection relays.
