What else can I help you with?
Why three phase induction motor has uniform torque?
The 3-phase currents in the 3 coils of an induction motor will produce a steady rotating magnetic field.
If a three phase induction motor runs at a speed greater than synchronous speed?
When an induction motor is pushed over synchronous speed it will become a generator and will deliver power back to the utility.
Condition of three phase in which there is no need of neutral?
A delta-connected system is described as being a three-phase, three-wire, system, and doesn't have a neutral. But a balanced star (wye) connected load (e.g. a three-phase induction motor) doesn't actually require a neutral.
Why are no starting components needed on three-phase motors?
Yes, by using a DOL Starter, which gives a controlled "soft-start" for the motor even though it is always connected in delta configuration.In this type of starting a 3-phase motor, full voltage is applied to the motor through relays and contactors. Its is the most common type of 3-phase motor starter used.DOL means Direct On-Line starter.
What happen when single phase supply of induction motor interrupted while driving the load?
That happens when the supply is turned off, and the motor runs down and stops.
Why three phase induction motor has uniform torque?
The 3-phase currents in the 3 coils of an induction motor will produce a steady rotating magnetic field.
Why each phase no load power factor of 3 phase induction motor is not same?
That indicates a fault in the induction motor.
Load test on 3 phase induction motor?
When you do a load test on a 3-phase induction motor you are checking the power factor, viz slip, and efficiency of the motor. You can test various loads with this test.
What should be the maximum difference between two phases in three phase induction motor at full load?
120 degrees
How do you calculate the no-load current of a three phase induction motor?
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.
If a three phase induction motor runs at a speed greater than synchronous speed?
When an induction motor is pushed over synchronous speed it will become a generator and will deliver power back to the utility.
Can 3 phase induction motor start and run rated speed by 2 phase?
yes, It would run as long as the motor was not coupled to a load. Coupled to a load the motor would have no torque and would stall.
What are the uses of single phase or three phase motor?
torque load, generation load, power correction load
What should be the current of siemens 75 kw motor at no load?
starting current of 3 phase 75 KW induction motor
Condition of three phase in which there is no need of neutral?
A delta-connected system is described as being a three-phase, three-wire, system, and doesn't have a neutral. But a balanced star (wye) connected load (e.g. a three-phase induction motor) doesn't actually require a neutral.
Why is my single phase induction motor drawing to many amps?
I have a single phase induction motor. It draws 8 amps on start up and climbs to 14-15 amps when I put a load on it. When I don't have a load it runs at 1 and climbs to 2-3 amps. It is normal operation for this motor to run at the lower number of amps with a load. But I don't know what is wrong.
What is the solution for running three phase induction motor at voltage less than its rated voltage to drive full load?
The solution to this problem is to get the same size motor in HP at the correct voltage. This way the motor can correctly drive the connected full load without tripping the motor protection.
