Apr 30,  · Motor Starting Current Table Are dived in peak current measurement is connected to the motor table for the original torque produced by several different types

In your case the nameplate gives the start-to-rated current ratio, Ia/In, as 7.5. This means that if rated voltage were applied to the motor, and its stator winding was delta-connected, then its starting current will be 7.5 x 160 or 1,200 Amperes. In certain instances, such a current is prohibitive.

Under a start condition with lots of current flowing in the motor’s stator winding, a very strong electromagnetic field is developed within the stator and this is imposed onto the rotor assembly. This induces a high voltage, and so high current, in the Squirrel-cage, resulting in a high strength magnetic field in the rotor.

To determine the starting current use the following formula: A Code letter table and corresponding factors can be found in Na tional Electrical Manufacturer s Association (NEMA) Motor and Generators Standards MG1, beginning in Section 2 Part 12.

Motor terminal voltage During the starting, th- e motor terminal voltage shoube ld maintained at approximately 80% of the rated voltage for type B motors having a standard 150% starting torque at full voltage with a constant torque load applied. A 81.6% rated voltage will develop a torque T = 0.8162 x 150% = 100%.

The in-rush current level exceeds the rated full load current (FLC) of the motor as shown on the motor plate by a long way, and is often quoted as 5-6x nominal FLC. Actually, the current
