Most industrial motor applications use either synchronous or induction motors - induction motors have characteristics that enable them to be used in applications where exact speed is not critical, as they have a slight droop in speed as they load from unloaded to full load - the most common application I am familiar with is in a power plant - induction motors are used for pumps, conveyor belts, compressors, and other drive systems. Induction motors (they appear electrically as inductors) create a lagging power factor, so very large motors may require some kind of line conditioning to reduce the circulating current they create. Synchronous motors operate at a single speed - defined by the frequency of the AC power they are supplied. (by adjusting the number of poles, and using variable output frequency machines you can have a wide variety of rotation speeds), and they have the ability for over or under exciting them to adjust power factor - important again in large industrial facilities where utilities charge for circulating current load)... Both of these motors require AC power, typically 3 phase...
