What is the ratio from no load current to full load current of an induction motor?
The ratio is between 30% to 40 %
Why less current increases in transformer than in induction motor when load is increase?
The current flowing through a transformer's secondary is the current drawn by the load, so it will be exactly the same as the current flowing through your induction motor -assuming that is the load. Don't really understand the point of your question!
What should be the current of siemens 75 kw motor at no load?
starting current of 3 phase 75 KW 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.
Why induction motor current increase when load increase?
The slip is proportional to the load torque in an induction motor. This can also be seen as a reduction in speed causing extra current to be induced in the rotor to supply the increased torque.
Why the no load current is more in an induction motor because of high reluctance airgap?
due to high reluctance air gap magnetisation current is very high as a result no load current is more
What happens to the rotor speed and rotor current when the mechanical load on an induction motor increase?
whenever the load increases,the current drawn by the motor to do or to fulfill the required energy to the load. so the current will increase generally.Increase in load will cause the full utilization of motor,so speed of rotor will decrease.
Can induction motor start at no load?
yes
What happens to the rotor speed and rotor current when the mechanical load on an induction motor increases?
rotor speed will decrease....the rotor current wil increase.....
What happen to the rotor speed and rotor current when the mechanical load on an induction motor increases?
rotor speed will decrease....the rotor current wil increase.....
Why each phase no load power factor of 3 phase induction motor is not same?
That indicates a fault in the induction motor.
Why the no load power factor is quite small in case of 3-phase induction motor?
Induction motors are designed for a certain power. If the power demand is lower than that, you still have to setup the magnetic fields as if you were going to supply that maximum power. As a result, the no-load power factor of an induction motor is quite small, i.e. poor.
