Synchronous AC Motors
Synchronous motors are termed synchronous because they inherently run at a constant velocity which is synchronized with the frequency of the AC power supply. These motors contain a rotor with a field winding which is powered by a DC voltage source. When powered, this winding operates as a permanent magnet. The rotational velocity of a synchronous motor is a function of the number of pairs of poles and is always a <ref>http://www.electricmotors.machinedesign.com/guiEdits/Content/bdeee2/bdeee2_1-4.aspx</ref>
