　　Introduction to motor technology

　　The basic purpose of a motor is to convert electrical energy into mechanical energy， and there are numerous types of motors to accomplish this. One main difference among motor types is the use of alternating current （AC） or direct current （DC）。 AC motors are further differentiated by the number of phases in the drive. Shaded-pole， AC induction， and universal motors typically use single-phase AC drives. These are good for appliances， pumps， fans， and stationary power tools. Poly-phase AC drives are more suitable for AC poly-phase induction squirrel-cage motors that require low cost， long life， and high efficiency in pumps， fans， blowers， conveyors， and compressors. Poly-phase AC is also used in more expensive AC synchronous motors that have no slip for use in clocks， audio applications， and industrial equipment. DC motors typically offer simple speed control or precision positioning though often at higher cost than AC motors.
