Horsepower is the Imperial unit of measurement for power. In North America, the horsepower is still used to define the rated output power of a motor, whereas the watt is used to define its corresponding input power. Because no device is 100% efficient, a motor's rated output power is always lower than its corresponding input power.
Elsewhere in the world, horsepower is considered to be an obsolete unit of measurement and, so, the watt is used to define both the rated output power and the corresponding input power.
A motor is driving something, like a pump, compressor, fan, winch, etc. In the United States, it is common to use horsepower as a reference unit for the amount of power necessary to drive the device. 1 horsepower is equal to approximately 746 watts.
CommentThis is only true in North America. Practically everywhere else in the world, the horsepower is now considered obsolete, and the watt is used.
One horsepower is equal to 746 watts.
A 100 horsepower electrical motor would consume 74,600 watts.
No. electric motors aren't heat engines.
The amount of copper in a particular motor is not determined by horsepower only, there is no relationship between the total weight of MAGNET WIRE to the HORSEPOWER of an electric motor. Determining factors are the vintage, frame, make, speed, and frame designation.
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.
One horsepower (electric motor rating) is equal to 746 watts.
First of all, what voltage are you going to use and second, what is the horsepower of the motor?
what motor is in it?
Service factor is gearbox horsepower rating over motor horsepower.

Displacement does not correspond directly to horsepower rating, and the horsepower ratings of various 155cc engines (not motors) can vary greatly.
