How does the starting of synchronous motor using dc generator as a load work-?
Starting of the synchronous motor using the DC generator creates a magnetic field.
Is it possible that you use motor as a generator input and electricity of the generator provide to a motor as a input?
If I'm understanding the question, you are proposing using one motor and one generator, and have the motor spin the generator up to speed, and have the generator attempt to supply power to the motor. The answer is yes, you can do this, but you will be losing energy, not gaining it. The motor and generator's efficiencies are less than 100%, so once you remove the outside source they will slow down until they come to a complete stope, without any other load connected other than themselves.
What problem occurs when a generator is run at 50 percent load?
After given 50% load that time engine was start to hunting
What size generator would it take to run a 400 hp 480 volt motor?
Well, if 80kW is your PEAK value, then you need an 80kw generator. If 80kW is your nominal current, you need to figure out what your peak current is. This will depend on the type of load. Is mostly motor loads? If so, your peak current may be significantly more than nominal, depending on the starting sequences of the motors. Clear as mud?
What causes a generator to stop?
There are many reasons why a generator should stop. If you are referring to a petrol (gasoline) generator, one reason is that it may be overloaded (i.e. its load draws too much current), causing the motor to stall.
Why load angle is positive for generator and negative for motor?
simply put a motor consumes power and a generator produces it. reactance of a generator = - reactance of a motor
Can DC series generator start on no load?
yes.it is possible to start dc series generator on no load condition
What is needed to perform a no-load bench test?
A bench and no load! Whatever you are testing has no load. It might be a generator or a motor for example. If a motor it wouldn't be connected to anything. If a generator it would have nothing plugged in.

What is an intermittent operation in which load conditions are regularly recurrent?
Motor, Generator
How is an electric motor different than an electromagnet generator?
Some types of motor can work equally well as a generator. A DC motor runs on a DC supply and supplies a mechanical load. If the load is removed the motor will free-run a little faster. But if the shaft is then driven faster than that, the current flows the opposite way and the motor has become a generator.
What happens if the synchronous motor exceeds its load capacity?
If load on a generator is greater than the generator can provide, the generator will begin to slow down. If it slows down too much, it will lose synchronism.
What is the difference between a DC motor and a DC generator Why can't you use a DC motor as DC generator?
A DC motor converts electrical energy to mechanical energy. The converted energy is provided to a mechanical load.A DC generator converts mechanical energy to electrical energy. The converted energy is provided to the electrical load (voltage, current referring load).A DC motor can be used as a DC generator and vice-versa.
What size generator would it take to start and run a 6 horsepower 220 volt electric motor on a air compressor?
To answer this question the full load amperage of the motor and what phase the motor is, should have been given. This answer uses the motor amperage give in the electrical code book and will be close for your purpose. A 6 HP is not a common size motor. 7.5 HP motor is 25.3 amps. Using a power factor of 90%. W = I x E x 1.73 x pf, W = 25.3 x 220 x 1.73 x .9 = 8666 watts. A 10kW three phase generator will probably start the motor if it is not under load when it starts. A 15 kw generator would be better. A single phase 7.5 HP motor draws 40 amps. W = I x E x pf = 40 x 220 x .9 = 7920. Again A 10kW single phase generator will probably start the motor if it is not under load when it starts. A 15 kw generator would be better.
Can a 2 hp electric motor run a 3000 watt generator?
Usual configuration, it is an engine that is used to turn a generator not a motor. If you mean it the other way around, will a 3000 watt generator have enough output to operate a 2 HP motor. 1 HP is equal to 746 watts. Keep in mind when a motor start it can take up to 300% of its full load amperage.
Can induction motor start at no load?
yes
