fractionalhorsepower

Fractional horsepower refers to electric motors with a power output of less than one horsepower. These motors are commonly used in a wide range of applications where high power is not required. The term "horsepower" itself is a unit of power, historically used to compare the output of steam engines to that of horses. One mechanical horsepower is equivalent to 746 watts. Therefore, fractional horsepower motors typically produce less than 746 watts of mechanical output power.

Fractional horsepower motors are categorized by their power ratings, such as 1/10 hp, 1/4 hp, 1/2 hp, and so on. These motors are found in everyday appliances like fans, blenders, vacuum cleaners, power tools, and small pumps. Their popularity stems from their cost-effectiveness, compact size, and suitability for tasks that do not demand significant torque or speed. They can be powered by alternating current (AC) or direct current (DC), with AC motors being more prevalent in household appliances due to their widespread availability from the power grid. The design and efficiency of fractional horsepower motors vary depending on their intended application and operating requirements.
