The following is a partial taxonomy of rotating electrical machines. Electrical machines may

be categorized for analysis purposes into alternating current (ac) or direct current (dc).

Some machines run on ac, some on dc, and some will run on either. An ac machine may

be synchronous or induction. A few examples of electrical machines include large

synchronous motors, small induction motors, universal motors, and permanent magnet

motors. Most motors found in the homes are usually induction machines or universal

motors. Universal motors are typically used in where high speed is needed such as in

blenders or vacuum cleaners. They will run on either “AC” or “DC”. Permanent magnet

motors are frequently used in toys and will work only on dc.
