The power required by the motor peaks at about 300% of rated power and 80% of speed with full voltage applied. But, the generator set supplies less than 300% power because starting voltage is lower than full voltage during acceleration, and because the generator set's rotating inertia transfers energy to the motor.

The power rating indicates the rate at which that machine can do work upon other objects. Thus, the power of a machine is the work/time ratio for that particular machine. A car engine is an example of a machine that is given a power rating. The power rating relates to how rapidly the car can accelerate the car.

Since horsepower is a measure of electric power, Watt's Law can be used to convert. Watt's Law gives us the formula to solve power given voltage, current, and AC power factor using this formula. P (W) = I (A) × V (V) × PF. The formula states that the power P in watts is equal to the current I in amps times the voltage V in volts times the ...
