What is a primary use for universal motors?

Universal motors are designed to operate on both alternating current (AC) and direct current (DC) supply, making them highly versatile. One of their primary uses is in vacuum cleaners and various household appliances. This is due to their ability to provide high starting torque and variable speed control, which are important features for devices like vacuum cleaners that require a strong initial pull to effectively suck up debris. Additionally, the compact size and lightweight nature of universal motors make them ideal for smaller appliances used in homes.

In contrast, while high-power industrial applications and electric vehicles utilize different types of motors that can handle larger loads and specific power requirements, universal motors are not typically suited for these applications due to their limited endurance and efficiency at high power levels. Wind energy generation relies on turbine generators, which are designed for sustained energy production rather than the short bursts of power that universal motors deliver. Thus, their design and functional characteristics align most closely with the needs of household appliances.
