A single phase 10 HP motor will draw aproximately 50 amps. A three phase 10 HP motor will draw aproximately 28 amps.
I don't see why not. It would have to be electromagets providing the magnetic field, and they would draw electricity from a generator that is powered by the motor. For electric cars, however, the brakes would draw too much power and drain the battery.
Depends on how big the motor is. A stronger motor will draw more amps then a weaker or less efficient motor. For example a wiper motor draws far less then a starter motor.
To answer this question the voltage of the motor must be stated.
The wire size and the circuit breaker for a 125 hp motor must consider the length of lead wire to the motor (essentially the distance of the motor from the supply). 125 hp is a VERY large motor and would be used only in industrial applications. You will need to consult a technician for proper advice, but the general answer to your question follows: The current draw on such a large motor would be approximately 300 amps. That is very large, and would require a wire size of 0000 AWG or 750M. 0000 AWG is 0.46 inches (11.68 mm) in diameter. As you can see, the wire is very large. It is not something you could install yourself.
This is a good indication that the motor is being overloaded. If the motor load is belt driven, remove the belt and then check the motor amps. If it goes back to normal FLA then there is a problem with the driven load. If the motor amperage stays high check the motor bearings for the problem.

Either. Motor size or your available power local to the pump installation are the determining factors. If you have to use a large motor, 220v requires less amp draw on the circuit and allows a smaller wire than a large motor running 110v. If 110v is already there and you only need a small motor, run 110v.
Watts = Volts times Amps. Therefore, if the voltage was 220 volts, the motor would draw 500 amps. If the voltage was 4,000 volts, the motor would draw 27.5 amps. The voltages for large powerful motors tend to be relatively high, for example in the 380 Volts to 11,500 Volts range.
Carrot cake
Depends on how big the motor is. A stronger motor will draw more amps then a weaker or less efficient motor. For example a wiper motor draws far less then a starter motor.
An automotive relay is a device that uses a small amount of current to control a large current-drawing device. For example; using a small switch on your dashboard to run the starter motor on your car. The starter motor on your car is probably the largest draw of electricity from your battery. When you need the electricity from your battery to start your car, you have to control that flow of electricity somehow. In the early days of electricity (automotive-related), the designers used a large wire or cable to allow that high flow of energy from the battery to your starter-motor. This became very impractical because of the excessive size of the wiring and switches needed to run that motor. Also, the longer the wire needed to run that device, the more drop in current and voltage would occur. Hence, another source of starting problems could surface. As technology improved, so did the devices to control the flow of electricity. The relay was born! Inside the relay is a small electromagnetic coil which again, uses the small amount of electricity from that small ignition switch on you dashboard or steering column to close a set of electrical contacts inside the relay. These contacts close allowing the large amount of electrical current to flow from your battery to the starter motor, without having to have the large wires inside the car, avoids the unnecessary length of those wires and provides the shortest path of that high-current electrical power to flow from your fingers to the starter! This is just one example of a relay's use, you can substitute any large electrical device for the starter motor, automobiles can have dozens of electronic and electro-mechanical relays!
You asked the wrong question. You need to know how many amps the motor uses. Then you can multiply amps times volts and get watts. Then you can multiply watts by hours and get watt hours. (For house electricity you pay for kilowatt hours.) A kilowatt is 1,000 watts.
To answer this question the voltage of the motor must be stated.
Depends on the voltage. If you are running off 120 VAC, a 0.5 horsepower motor would draw 3.1 A.
