When current is induced in the rotating coil in an electric generator then a counter couple acts on the current carrying rotating coil in the magnetic field(in accordance to the principle of dc motor). This counter couple is called back motor effect.

∙ 11y agoIn generator,production of counter clockwise opposes the rotational motion of coil.This is known as back motor effect in generator. ACTUALLY BACK MOTOR EFFECT MEANS "PRODUCTION OF TORQUE".

1000 watt generator power can it power a oil burner?
Watts = amps x volts. 1000/120 = 8.3. Assuming the oil burner motor is 120V then the generator has the ability to produce 8.3 amps. Find the amperage on the burner pump motor, if it is in this range it will work. The closer the pump amperage is to the generator output the more effect it will have on slowing the generator down on the start. Motors draw up to 300% on start up, this is what makes the generator lag when a motor is connected as a load.
Can a 1 horse power motor run on a 2500 watt generator?
Maybe that motor can turn the generator, but you won't get 2,500 watts out of it. 1 horsepower is only 746 watts. <<>> A one HP motor draws 16 amps on 115 volts and 8 amps on 230 volts. Using the formula W = A x V = 16 x 8 = 1840 watts. It shows that the motor will run on a 2500 watt generator. Where the problem might arise is getting the motor to start. Generally a motor takes 300% of its running current to start. 16 x 300% = 48 starting amps. Back to the first formula W = 48 x 115 = 5520 watts. The 2500 watt generator is just under half of the wattage needed to start the motor. Try the generator, one of three things will happen, one the generator will stall, two the generators breaker will trip or three the motor will run. Some generators have a temporary overload output built into them that will allow the above generator rating output for a certain amount of seconds. If your generator has this feature then the motor will probably start.
Will a 2800 watt generator run a 550 watt electric cement mixer motor?
The sizing of the generator is dependant on the size of the electric motor driving the mixer.
Hans oersted's discovery of magnetic affect of an electric current can be considered an event of?
Oersted's discovery was the beginning of Electromagnetism, and showed the motor effect. Oersted inspired Faraday and Maxwell to create the generator effect and the general theory of Electromagnetism.
Is an electric motor and a generator very similar devices or entirely different?
They are very similar devices. They both involve a rotating shaft and coils of wire used as electromagnets. However, only certain types of simple DC motors, can be used as generators with no modiication. AC generators need careful control of the feild coils, via special circuits. Putting AC back into an AC generator will not make it work as a motor. The small DC motors found in toys, can be used directly as a small DC generator. You will find this in practice, in hand generator flashlights. The generator used for charging the battery, is no more than a model motor.
Can a motor act like an electric generator?
when the motor runs more than rated speed it produces leading current and results act as a generator. (or) the motor act as generator when it produces more back e.m.f
How does the generator terminal voltage rise and the motor speed fall when the brushes are given a backward shift in a generator or forward shift in a motor?
A generator is a back up of power. A generator can only give so much voltage.
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 a motor operate as generator?
Yes, by giving mechanical power to motor . It acts as a Generator.
Did Mike Faraday invent the generator and motor?
Mike Faraday did invent the generator and motor.
How does ac electric motor convert in to an alternator?
a motor is a generator and a generator is a motor, if you are applying a voltage to turn the rotor its a motor and if you are turning the rotor and taking the voltage off the terminals its a generator or alternator.
Why Back EMF occur in only dc motor?
It doesn't. It exists in all electrical machines, d.c. or a.c., motor, generator, or transformer.
What are the differences between the parts of a generator and the parts of a motor?
In principle a generator is the same as a motor. In a dc motor the voltage generated by the rotating armature is slightly less than the supply voltage which causes power to flow in from the supply. If an engine is then coupled to the shaft causing it to rotate faster, then it generates more voltage and power flows back into the supply. That is how a motor becomes a generator.
Explain how the induction motor gets loaded when the DC generator is loaded?
when the dc generator is loaded current will be drawn from it, therefore a back emf Will be generated, which opposes the motion of a generator, and hence, that opposition loads the three phase generator
How do you identify a motor and a generator without operation?
a motor drives something a generator is driven by something
How do you convert a DC motor to a generator?
all the electrical machines can be run either as a motor or as a generator. but dc machines, A motor can be run as generator and vice versa with little modification
