Salient Pole Synchronous Generator: A Salient Pole Synchronous Generator, as shown in Fig. 4.29, is distinguished from a round rotor machine by constructional features of field poles which project with…
Phasor Diagram of Synchronous Motor: The Phasor Diagram of Synchronous Motor is the most important element of a power system. It converts mechanical power into electrical form and feeds it…
What is Skin Effect and Proximity Effect?: What is Skin Effect and Proximity Effect? - The distribution of current throughout the cross-section of a conductor is uniform only when DC…
Inductance of Composite Conductor Lines: Future 2.6 shows such a single-phase line comprising inductance of composite conductor lines A and B with A having n parallel filaments and B having…
Vector Control of Induction Motor: The sole idea behind the vector control of induction motor is to have an electrical drive which must offer superior performance than widely used separately…
Types of Forced Commutation: It was observed from the discussion on choppers and inverters that in thyristor systems fed from dc supply, the forward current does not pass through zero…
Induction Motor Speed Control Methods: The only way to control the speed of a synchronous motor is to control the input frequency and voltage such as to keep V/f constant.…
DC Motor Control through Converters: DC motor control is conveniently and efficiently achieved by phase-controlled converters wherein the ac input voltage is converted to a controlled dc output. The commutation…
