  • Handbook of Electrical Design Details, Second Edition > ELECTRIC MOTORS AND STARTERS
    Universal motors are classed as variable- or adjustable-speed motors because their speed can be controlled by thyristors, silicon controlled rectifiers (SCRs) or triacs , and variable resistors. These motors power portable tools such as drills , saws, and sanders, as well as vacuum cleaners, food …

    This control can be used, for example, to adjust the suction of a vacuum cleaner, the brightness of room lighting or the speed of food mixers and electric drills . With triacs and thyristors it is possible to produce high performance mains controllers which use only a …
