Fractional horsepower is a measure of power output that's important to understand when it comes to small motor performance. What is it, and how does it compare to regular horsepower? Here's your quick rundown of fractional horsepower in today's small motor systems.
Horsepower is the basic measurement of how much output work a motor can perform at any given time. Similarly, fractional horsepower measures motor output but in increments of less than 1 horsepower.
So, if a motor is too small or otherwise is meant to work at an output rate of anything less than 1 horsepower, that output will be measured in fractional horsepower. Common examples of fractional horsepower figures include 1/3 horsepower, 1/2 horsepower, and even 1/100 horsepower.
There are many motors all around us that use this type of fractional output measuring system. These types of motors are generally of a size with which they can easily be carried by a person but just a bit too large to fit in your average pants pocket. They also come in four types: alternating current (AC), direct current (DC), brushless, and universal.
One common example of a motor that puts out fractional horsepower is the kind that blenders use to blend and puree various foods. Another great example can be seen at work turning exhaust fans in many bathrooms. Yet another example comes to us by way of many types of power tools and handheld pumps used for moving water. All of these examples are of small motors that just don't need the size and power of a motor that would otherwise be measured in horsepower.
