How will the armature current and the output power of a dc shunt motors change with increasing load?
With increasing torque load the armature tends to slow down; the motor draws more current to compensate, and if there is armature resistance the back emf generated by the armature falls to allow the increased current to flow, which causes the motor to settle at a lower speed. The mechanical output power is the speed times the torque, and increasing the torque increases the power output provided the speed does not drop much.
How many electricity consume 5HP motor in 1 hour?
I assume you are asking how much energy a 5-hp motor will consume in one hour?The first thing to understand that a motor is rated according its output power which, in North America, is expressed in horsepower and, elsewhere, in watts. So, the output power of your motor is 5 hp, which is equivalent to 5 x 746 = 3730 W.Next, you need to find out its full-load efficiency. You then need to divide the output power by the efficiency to determine its input power -remember, input power is always higher than the output power.Once you have found out its input power, convert that into kilowatts and multiply it by one (hour) to determine the energy used in kilowatt hours.
A receiver requires 10nW as input power if all the system losses add up to 50dB then how much power is required from the source?
here, the power required by the receiver is the output power and that required from the source is input power. Gain in dB=10 log(output power/input power) we have, loss in dB = -gain in dB = 10 log(input power/output power) or, 50 = 10 log(input power/10nW) or, anti-log(5) = input power/10 nW so the power required from the source is antilog(5)*10nW = 1 mW
When a PNP transistor is connected in a circuit in the manner it can be used as a power amplifier because?
the output voltage will be much larger than the input voltage
What is the loading arrangement used in dc motor?
the loading arrangement used in normal electrical machines is brake drum - spring balance arrangement. This is used to calculate the torque and output power. the formula for torque is 9.81*(diffference between the spring balance) * radius of brake drum. thee output power obtained is 2*π*motor speed*torque obtained
Does motor rating mean the electrical power required into a motor or the electrical power of the motor's output?
Normally you would specify a motor to do a particular job by the mechanical power output you require.A motor takes electrical power "in" and produces mechanical power "out".Read whatever it says on the motor's rating plate or user-guide.The mechanical energy output of a motor is measured in various units around the world: for example in watts, horsepower (or brake horsepower).Another answerThe above answer is quite correct in stating that a motor's output power is its rated power as it's a guide to how much load it can drive.Power is simply a rate - the rate of transfer of energy. The horsepower is the Imperial unit of power, whereas the watt is the SI unit of power. In the US the output power of a motor is typically still measured in horsepower whereas in Europe the use of horsepower is almost obsolete, except for small "fractional horsepower" electric motors, and both the input power and the output power of a motor are measured in watts or, more likely, kilowatts.
If an elevator motor lifts a load of 10 slugs through a distance of 20 feet in 8 seconds how much power is the motor producing?
The power output would be corralated with the gearing of the motor, but assuming a perfect 1:1 ratio you would have a force of 25lbs, and a power output of 1600 watts.
Is the current produced by a dc motor the same as the current given to it?
A motor uses electricity; it does not produce it. If you are somehow using a DC motor as a generator, then it will produce power equal to the input power minus the motor losses. If the input power is you spinning the rotor, the output power will be directly proportional to how much work you put into spinning the rotor.
How will the armature current and the output power of a dc shunt motors change with increasing load?
With increasing torque load the armature tends to slow down; the motor draws more current to compensate, and if there is armature resistance the back emf generated by the armature falls to allow the increased current to flow, which causes the motor to settle at a lower speed. The mechanical output power is the speed times the torque, and increasing the torque increases the power output provided the speed does not drop much.

How much power is required by a 1 horsepower motor?
1 horsepower is the output power - the power produced. The power it uses is more, because no engine is 100% efficient. How much more, depends on the type of engine; an explosion engine (such as one that uses gasoline) is basically a heat engine, with an efficiency of perhaps 1/3; that means that about three times the output power is actually consumed. For an electrical motor, the required electricity will be only a little more than 1 horsepower (about 742 watts running current, more when the motor is getting started).
Which motor is more powerful the one that is marked as 230V 50Hz 1400W or the other one that is marked 120V 60Hz 12A?
The higher wattage motor would be the 120 volt at 12 amps which equals 1440 watts.Another AnswerTo answer your question, it's necessary to compare 'like with like'. And the information you supply doesn't enable us to do this because, for the 230-V motor, you are specifying its output power whereas, for the 120-V motor the supplied information only allows us to determine its inputpower! The rated power of a motor always describes its output power, never its input power. This is because its input power is of academic interest only; what matters is how much power it can deliver to its mechanical load.So, in the case of the 230-V motor, we know that its output power is 1400 W.As for the 120-V motor, we are given enough information to calculate its input power (1440 W) but, without knowing its efficiency, we can't really determine its output power.So the simple answer is that we don't really know which motor is the more powerful based on your information, but for the 120 V motor to match the output power of the 230-V motor, it would need to be 97% efficient... which is unlikely (too high) for a motor.So I would have to say that the 230-V motor is likely to be slightly more powerful than the 120-V motor.
How much energy is being used by the sun?
The Wikipedia lists the luminosity - basically the power output - as 3.846×10 to the power 26 Watt (which means, that much joules are output every second). Due to conservation of energy, and assuming the Sun works more or less continuously, that's also the power which is used up inside the Sun.
How much power does a 1HP motor require?
The short answer is - one horse power, or 746 watts. But machines do not have 100% conversion efficiency so the electric power taken by a motor is more than the mechanical power output. Electric motors are made more efficient at the higher powers, so while a 1 HP motor might have an efficiency of 80%, a 10 HP motor might have an efficiency of 90% and a 100 Hp motor 97%. This is a matter of design because the higher-power motor needs to waste less of the total power, so it is given thicker wire and a more massive magnetic core (proportional to power) than a small motor.

How much horse power should you have for a motor bike?
as much as you whant
Can you run a AC generator with help of a DC motor if yes how if no why not?
Yes, but the power you get out will be much less than the power you put into the motor.
