Testing of DC Machine or Swinburne Test: Testing of DC Machine or Swinburne Test - Machine efficiency, in general, has been discussed already. The approach here will be to apply…
External Characteristics of DC Shunt Generator: The External Characteristics of DC Shunt Generator can be predetermined from a knowledge of the OCC and armature and field resistances (which can be…
Characteristics of Separately Excited DC Generator: With the advent of silicon-controlled rectifiers, the importance of the dc machine as a generator has considerably reduced as SCRs can be employed to…
Self Excited DC Generator: Rather than arranging a separate dc source for excitation purposes, practical generators are always excited from their own armature terminals, this method of excitation being known…
Commutation in DC Machine or Generator or Motor: One coil each under an adjoining pole-pair is connected between adjacent commutator segments in a lap-wound dc armature, while in a wave-wound…
Synchronous Generator Ratings and Loss Dissipation: The Synchronous Generator Ratings and Loss Dissipation is its operating voltage, frequency, speed and kVA/MVA output at a specified power factor. In case of…
Principle of Induction Motor | Torque Slip Characteristic: Principle of Induction Motor has not been introduced so far. Consider a cylindrical rotor machine with both the stator and rotor wound…
Energy in Magnetic System: Energy in Magnetic System - The chief advantage of electric energy over other forms of energy is the relative ease and high efficiency with which it…
