How many watts is 1 horsepower of a motor?

Answer 1

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.

Answer 2

It varies with the exact motor you choose, as different motors will have different efficiency ratings.

The accepted conversion between watts and horsepower is 1hp = 746 watts, but no motor is 100% efficient, so you will not find a 1hp motor that actually draws only 746 watts.

In general, the majority of 1 HP electric motors out there will draw between 1,000 and 1,500 watts.

Answer 3

746.27 watts.
There are 746.27 watts in one horsepower.

Answer 4

It takes 746.27 W to equal one horsepower.

Answer 5

746 watts in every HP regardless of voltage.

Answer 6

The definition is that 746 watts equal one horse-power.

Answer 7

One horsepower is equal to 746 watts.
