Single-phase AC motors are commonly available in horsepower ratings of up to what value?

Single-phase AC motors are commonly available in horsepower ratings up to 10 horsepower. These motors are widely used in applications where lower power requirements are needed, such as in residential and light commercial settings. While motors of smaller capacities, such as 1/2 and 2 horsepower, are also frequently encountered, the maximum typical rating for single-phase motors can reach up to 10 horsepower. This rating allows these motors to be used for various tasks, including running larger appliances or equipment that require a higher power output.

In practical applications, single-phase motors rated above 10 horsepower tend to be less common because three-phase motors are typically preferred for higher horsepower requirements due to their efficiency and power delivery capabilities. Thus, the 10 horsepower rating serves as a common upper limit for standard single-phase AC motors in many applications.
