ABSTRACT
An electric motor converts electrical energy to mechanical en ergy. Motors come in all manner of shapes and sizes. There are electromagnetic direct current (DC) motors and electromagnetic al ternating current (AC) motors and a number of variations of each. AC motors are typically used for large machinery (such as machine tools, washers, dryers, and the like) and are powered from an AC power line. You might run across AC motors with titles such as single-phase, split-phase, capacitor start, permanent split-capacitor, shaded-pole and three-phase motors. AC motors are seldom used in mobile robots because a mobile robot’s power supply is typically a DC battery.
