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.
What else can I help you with?
How many percent will be the starting current for motor?
Motor starting current is typically 5-7 times the rated current of the motor. (For three phase induction motors)
What should be the current of siemens 75 kw motor at no load?
starting current of 3 phase 75 KW induction motor
Why you use DOL starter in starting of motor?
because of starting current of induction motor is very high and it damages the insulation of motor
Why DC motor current ripple?
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".
Does induction motor has rotor winding?
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.
What is induction motor?
Induction motor is an AC electric motor which uses electromagnetic induction to induce the electric current in the rotor to produce torque.
Slip power in a induction motor?
slip power is a power which is develop by the induced voltage and current in an induction motor
Difference between transformer and 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.
How are the two circuits of an induction motor similar to the circuit of a transformer?
They are magnetically coupled--a current in one circuit induces a current in the other one in both a transformer and an induction motor.
What is the power factor of 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.
How many percent will be the starting current for motor?
Motor starting current is typically 5-7 times the rated current of the motor. (For three phase induction motors)
What does the Induction motor do that Nikola Tesla invented?
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.
Why using on motor star delta starter?
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!
How does the 3-phase induction motor acts like 2-phase induction motor if a phase is disconnected from supply?
yes the motor will run but will draw more current and the torque will be not constant means not smooth due to unbalanced current
What is the load current of 90kw induction motor?
90/3=30ma
What should be the current of siemens 75 kw motor at no load?
starting current of 3 phase 75 KW induction motor
How do you calculate magnetizing impedance of the induction motor?
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.
