Simply that horses were used before motors and engines. The standard used to measure how efficient a machine was therefore a horse. So a 2 HP (Horse Power) motor could do the work of 2 horses.
CommentThe output power of a machine is only measured in horsepower in the US; elsewhere, it's measured in watts.

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).
What is a 440 motor bored 030 over?
A 440 motor bored .030 over means that the cylinders of the engine have been enlarged by 0.030 inches beyond the standard size to increase displacement. This modification allows more air and fuel mixture to be burned, potentially increasing horsepower and torque output.
What is the operation of a hydraulic dynamometer?
A hydraulic dynamometer operates by using hydraulic fluid to create resistance against the rotation of an engine or motor. This resistance is then measured to determine the power output of the engine or motor. The dynamometer can be used to test the performance, torque, and power of various types of engines and motors.
How many watts is 1 horsepower of a motor?
In theory one horse power equals 746 watts. They are both basic measures of power. A 1 HP motor however draws more than 746 watts because to give a mechanical output of 1 HP/746 watts at the shaft, the motor has to draw more than 746 watts of electric power to cover losses in caused by resistance in the windings and the iron core of the motor, and friction in the bearings. A typical efficiency for a motor would be 90% so that the electric power used would be 829 watts. <<>> For clarification in all electrical calculations regarding horsepower, 746 watts per horsepower is used.
When the motor in an engine turns what form of energy does it have?
When the motor in an engine turns, it has mechanical energy. This energy is derived from the movement and rotation of the engine components.
What is B.H.P in 3 phase induction motor?
BHP stands for 'brake horsepower', and simply means it is describing the output, rather than the input, power of the machine. Although a motor's output power is expressed in horsepower in North America, elsewhere it is expressed in watts.
Is the brake power the output power of an engine?
No, "Horsepower" was originally defined to compare the output of steam engines with the power of draft horses. "Brake horsepower" (BHP) is the amount of work generated by a motor without taking into consideration any of the various auxiliary components that may slow down the actual speed of the motor. Sometimes referred to as pure horsepower, brake horsepower is measured within the engine's output shaft.
What is the horsepower of a Triumph America?
According to Triumph, it is 54 bhp (brake horsepower) @ 6,750 rpm. According to Encyclopedia Britannica, horsepower at the output shaft of an engine, turbine, or motor is termed brake horsepower or shaft horsepower.
What is a five-horsepower induction motor?
It's an a.c. motor with an output power of 5 horsepower or roughly 3.75 kW.
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).
How much horse power does a 350cc motor have?
The horsepower of a 350cc motor can vary depending on its design and application, but it typically ranges from about 10 to 30 horsepower. For example, a 350cc motorcycle engine might produce around 25 to 35 horsepower, while a 350cc four-stroke engine in a lawn mower might output around 10 to 15 horsepower. Overall, the specific horsepower will depend on factors like engine type, tuning, and intended use.
What equivalent size electric motor will replace a 8 HP gasoline engine?
If the gasoline engine must supply energy at the rate of 8 horsepower to its load, then so too must the electric motor. Expressed in watts, 8 horsepower is equivalent to 6 kilowatts. So the output power of the motor must be 6 kilowatts.
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 is horse power of a 415 volt 3 phase 7.5 kW electric motor?
Motors are rated according to their output power, never their input power. This is because it is the output power that determines the load the motor will be able to handle. The output power, of course, is lower than the input power due to the machine's losses.In North America, the output power is generally expressed in horsepower, whereas its input power is measured in watts. In the rest of the world, the horsepower is considered obsolete, so both the output power and the input power are measured in watts.As there are 746 W to the horsepower, your 75 kW output motor would be equivalent to approximately 100 horsepower.
How much horsepower does a 900 cc motor produce?
The horsepower produced by a 900 cc motor can vary widely depending on the engine design, type, and tuning. Generally, a 900 cc engine can produce anywhere from 70 to 120 horsepower, with performance-oriented models potentially exceeding this range. Factors such as forced induction, fuel type, and engine efficiency also play a significant role in determining the exact output.
How much horsepower does the Harley Davidson 103 motor have?
The Harley-Davidson 103 motor, which is a part of the company's Twin Cam engine family, typically produces around 100 horsepower. However, actual horsepower can vary slightly depending on the specific model and tuning. The 103 engine is known for its strong torque output, providing a robust performance characteristic that many riders appreciate.
How much horsepower is a 70cc motor?
A 70cc motor typically produces around 2 to 3 horsepower, depending on its design and efficiency. This power output is common in small engines used in scooters, mopeds, and other lightweight vehicles. The actual horsepower can vary based on factors like tuning and the specific application of the engine.
