This course provides an introduction to electrical circuits and covers a range of essential topics in rotating electrical machines. These topics include DC series motors, DC shunt and compound motors, motor speed and torque, motor performance, split-phase AC motors, capacitor-start AC motors, permanent-capacitor and two-capacitor motors, as well as three-phase AC induction motors. DC generator, AC alternator for mobile generation as well as synchronous, for power factor correction will be covered.
