In 1827, Hungarian physicist and Benedictine priest Ányos Jedlik used electromagnetic coils to develop a rudimentary motor he called an “electromagnetic self-rotor.” The historic motor still works to this day, and is on display at Budapest’s Museum of Applied Arts.
Electric motors can be classified as either an AC motor or a DC motor; or both, in the case of universal motors. Examples of AC motors include induction and synchronous motors, while brushed and pancake motors are common DC motors.
While a conventional DC motor's brushes can be replaced, the commutator that they come in contact with is another matter. Due to constant friction, this part of the rotor which receives DC current from the brushes will eventually wear away. When this happens, replacement of the motor is warranted.
A broken electric motor can cause other problems for devices they are connected to. Always disconnect the motor from its power source before investigating.
