Synchronous Motor

Synchronous motors transform electric power from an alternating current system into mechanical power. The armature winding, usually on the stator, is the current carrying winding. The configuration of the rotor determines the type of synchronous motor and usually employs dc-excited field windings. Synchronous motors are built for operating at a power factor or 1.0 or 0.8 lead. Reactance is measured in a steady-state condition in which a circuit’s values remain essentially constant, occurring after all initial transients or fluctuating conditions have settled down.
