This document provides information about synchronous motors. It discusses the characteristics of synchronous motors including their stator, rotor types, and ability to start as an induction motor. It also covers synchronous speed calculation, equivalent circuits and phasor diagrams, V-curves, applications, starting methods, torque types, losses, and comparisons with induction motors. Worked examples are provided to calculate induced EMF, current, power factor and torque values for synchronous motors operating under different load and excitation conditions.
