A 750w motor might also be rated as a

750W * 1hp/746W = 1.0 hp.

To figure out which of these options is correct, we need to understand the relationship between watts and horsepower.

First, let's establish the conversion factor between these two units of power:

1 horsepower is approximately equal to 745.7 watts.

Now, we can calculate the power in horsepower using the given 750 watts value:

750 watts ÷ 745.7 watts/horsepower ≈ 1.006 horsepower

So, if a 750W motor is approximately equal to any of the given options, it would be closest to a 1 horsepower motor.
