Calculate the amount of potential energy required. Then divide by the power.
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.
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.
simply put a motor consumes power and a generator produces it. reactance of a generator = - reactance of a motor
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.
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.
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.
The amount of energy that a motor transfers every second can be calculated by multiplying the power output of the motor by the time duration over which the power is being exerted. The unit of power is watts (W), and the unit of time is seconds (s). Therefore, the energy transfer per second can be expressed in units of joules per second, which is equivalent to a watt.
An airplane is a VEHICLE. It's power is provided by a MOTOR.
Calculate the amount of potential energy required. Then divide by the power.
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.
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
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?
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.
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.
The power required to do 60 joules of work in 20 seconds is determined by the formula: Power = Work / Time. Therefore, Power = 60 joules / 20 seconds = 3 watts. So, 3 watts of power is necessary to do 60 joules of work in 20 seconds.
