<P> Operating at normal power line frequencies , universal motors are often found in a range less than 1000 watts . Their high speed makes them useful for appliances such as blenders , vacuum cleaners , and hair dryers where high speed and light weight are desirable . They are also commonly used in portable power tools , such as drills , sanders , circular and jig saws , where the motor 's characteristics work well . Many vacuum cleaner and weed trimmer motors exceed 10,000 RPM , while many Dremel and similar miniature grinders exceed 30,000 RPM . </P>
