How many seconds would it take a 1200 W motor to raise a 9800 N to 10 m high?
Calculate the amount of potential energy required. Then divide by the power.
An electric drill has an efficiency of 75 percent. If the motor has a power input of 700 watts and is run for 30 seconds. How much actual work is done. How would I get a kilojoules answer?
Power input = 700 WEfficiency = 75% so power output = 75% of 700 = 525 W Time = 30 seconds => Work done = 525W * 30s = 15750 W.s = 15750 Joules = 15.75 kiloJoules.
Why can a car accelerate from 0 to 60 in less than 4 seconds?
Most likely, the motor can not handle the horse power it needs. Some cars are built to achieve that. But they are cars that are built for racing, or they have more horse power than the average family car.
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
What motor has more power one at 120 volts or one at 208 volts?
The voltage of the motor does not determine the power. However it does determine how many Fla... Or full load amp it will have when the motor is at highest speed. Usually the lower the voltage the higher the amps On the same motor. Most motors will have a name plant with this information and you should always get the amount of horsepower motor you need and make sure it will be compatible with your power source.
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.
How many watts of motor are required for 30 kg material?
If it's to lift 30 kg, it depends how far it is to be lifted and how quickly the lift takes to complete. To lift 30 kg through 10 metres requires 30 x 9.8 x 10 joules of energy, that is 3000 Joules. To do that in 10 seconds needs 300 watts, which would be about half a horse power motor. To do it in 5 seconds the power would be 600 watts - a 1 horse power motor.
Is an airplane a motor or a vehicle?
An airplane is a VEHICLE. It's power is provided by a MOTOR.
Is your power into motor equal to your power out of motor at no load?
For a motor's output power to equal its input power, the motor's efficiency must be 100%. As no machine, particularly a rotating machine, can possibly achieve 100% efficiency, there is no condition under which its output power can ever match its input power.
How do you test a power window motor?
Disconnect wires from motor and check to see if you have power and ground going to motor--if so motor is bad if not have to check wiring and switch to that motor
How many seconds would it take a 1200 W motor to raise a 9800 N to 10 m high?
Calculate the amount of potential energy required. Then divide by the power.
Slip power in a induction motor?
slip power is a power which is develop by the induced voltage and current in an induction motor
How do you calculate 3ph AC motor power?
How do you calculate 3ph AC motor power?
Why does heater motor not work on a 1987 cariolet changed the motor have power to the rheostat?
The resistor has power going to it but, the resistor may be burned out and no power is coming out of it. Check for power at the blower motor connection.
How do you fix power window 2003 Chevy pickup?
remove door panel check to see if you are getting power and ground to motor. If so, bad motor--if no power to motor, check to see if you have power to switch if so ,bad switch--if not bad power feed to switch close but if the switch not on, you never get power to the motor.
How do you replace power window motor on 1993 Sunbird?
power window motor removal 93 sunbird
What is the actual power of a 5 horsepower motor?
A 5 horsepower motor would have 3,730 watts of power.
