What else can I help you with?
What is a a comparison of a machines work output with the works input that is mechanical?
Output power divided by input power, for a machine, is called the machine's efficiency. It need not be mechanical energy.
What is the output of a bicycle generator?
The output of a bicycle generator is electricity, which is generated by pedaling the bicycle to power a generator that converts mechanical energy into electrical energy.
What is the power output of the human heart?
The mechanical power of the human heart is ~1.3 watts. It takes a much higher rate of energy turnover (~13 watts) to provide this mechanical power, since the mechanical efficiency of the heart is very low (less than 10%).
What is a mechanical Effeciency?
Mechanical efficiency is a measure of how well a machine converts input energy into useful output energy. It is calculated by dividing the actual output power of the machine by the input power and multiplying by 100% to get a percentage. A higher mechanical efficiency indicates that less energy is lost in the conversion process.
Unit of power used mainly in the US?
This depends on the situation. The main power unit used for electric power output is generally the Watt (W), while the main power unit used for mechanical power output is often the horsepower (hp).
What is a hydrostatic system?
Hydrostatic systems take the mechanical rotary output of an engine or electric motor and convert it to a hydraulic source of power using a hydraulic pump. The hydraulic power is converted back to mechanical power using a hydraulic motor
What is an electric converts mechanical energy into electrical energy?
Plenty of these to quote. For example a power station generating set converts the mechanical power of the steam turbine into the electrical output of the generator. In an auto, mechanical power from the engine is converted to electrical power in the AC generator which powers all the car's electrics and charges the battery
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.
What are the three main functions that gears perform in a mechanical system?
Transmit rotation, power, and change "input to output" ratio's.
Why rating of motor is given in HP?
Motors are only rated in horsepower in North America, in most other countries, they are rated in watts. The reason for doing so, is that a motor's power is always expressed in terms of its output power -that is the maximum power it can supply to its mechanical load. If, as in North America, a mechanical load is expressed in horsepower, then so is the output of the motor; if, as elsewhere, a mechanical load is expressed in watts, then so is the output of the motor.Don't forget a horsepower is simply the Imperial unit for power, whereas the watt is the SI (metric) equivalent. 1 HP = 746 watts.
Will ther be any loss in terms of power if you ran a 550 volts motor with 380 volts?
There will be a significant reduction in the mechanical power output available from the motor.
How motor kw is been decided?
You can measure the output power of the motor (mechanical power or shaft power) by a speed and torque sensor. The product of speed (angular velocity to be precise) and torque is power. Is this case the output power. The SI unit of power is W, kW is 1000 W. So the power/1000=power [kW].
