This current is consumed no matter if there is a load attached to the output or not. Also, measure the motor current under this no-load condition.No-load supply current is the amount of current that a device consumes when the device is just sitting there. No-load losses depend primarily upon the voltage and frequency, so . In Figure 1, you see that this sensor has a current consumption of 15 .The current drawn by the induction motor when it is not coupled to the driven equipment is called the no-load current of the motor.The full load current I (A) in amps is equal to 1000 times of transformer rating S (kVA) in kVA divided by the multiplication of root 3 times of line to line voltage V (V) in volts. Includes Formulas.and no load conditions. It depends on the design and type (not all motors are induction) of the motor and how well it has been maintained. It is the maximum amount of current that can be delivered to the electrical equipment under a fault condition. I (A) = S (kVA) *1000 / (1.As both Andy aka and Bimpelrekkie have commented, there is no useful formula because there are far too many variables both known and unknown.
