All Transformers, single phase or three phase have a "no-load current" rating. That is simply the nameplate rating of the Xformer in VA, (volt-amps) or KVA (1000Volt-amps) for larger Xformers. Simply divide the nameplate rating in VA or KVA by the supply voltage and you'll get the Xformers potential maximum output in ampheres.
Motor starting current is typically 5-7 times the rated current of the motor. (For three phase induction motors)
starting current of 3 phase 75 KW induction motor
because of starting current of induction motor is very high and it damages the insulation of motor
The induction of a DC motor while rotation lead to a non continuid current. This AC part of the DC csupply current is called ripple current. You can measure this and see if the motor is moving and also you can count the ripple per second and have the motor speed "RMS".
Yes, the induction motor has a rotor winding. It is usually one turn, shorted. This is how the magnetic fields generated in the stator induce a current in the rotor, which subsequently generates a torque from the opposing magnetic fields, stator to rotor.
Induction motor is an AC electric motor which uses electromagnetic induction to induce the electric current in the rotor to produce torque.
slip power is a power which is develop by the induced voltage and current in an induction motor
1. Induction Motor has an air-gap but transformer has no air gap rather it is mutually link. 2. Induction Motor has high no-load current than transformer. 3. Induction Motor is a dynamic device. 4. Induction Motor has high power factor.
They are magnetically coupled--a current in one circuit induces a current in the other one in both a transformer and an induction motor.
Induction motor comprised inductor as the most part in it and an inductor has the characteristic to oppose the change of current, i.e., it has lagging power factor as current lags behind the voltage. Hence, an induction motor works on lagging power factor.
Motor starting current is typically 5-7 times the rated current of the motor. (For three phase induction motors)
The induction motor is an alternating current motor that Nikola Tesla invented. It generates motion by inducing a current in a rotor when coupled with an alternating current power source. This design allows for a simpler and more efficient electrical motor compared to direct current motors.
because at the starting the induction motor drawn a heavy current thats why we use starter to increase the starting resistance of the induction motor!
yes the motor will run but will draw more current and the torque will be not constant means not smooth due to unbalanced current

The magnetizing impedance of an induction motor can be calculated by performing no-load tests. During these tests, the motor is operated without any mechanical load, and its input power and current are measured. By applying the equivalent circuit model of the motor, which includes the magnetizing impedance, the impedance value can be calculated using the measured data.
