What type of motors are classified as having a rating of less than 1 horsepower?

The classification of motors that have a rating of less than 1 horsepower is specifically known as fractional horsepower motors. These motors are typically designed for applications that require lower power outputs, making them suitable for small devices, tools, and appliances.

Fractional horsepower motors are widely used in everyday equipment due to their efficiency and ability to perform tasks without the need for a large amount of electrical energy. This classification includes various types, such as small AC and DC motors, which serve in applications like fans, pumps, or small conveyors.

This distinguishes them clearly from standard motors, high-power motors, and heavy-duty motors, which generally have higher power outputs and are designed for more demanding applications. Understanding this classification is crucial for selecting the appropriate motor for specific applications where power requirements are modest.
