Variable Reluctance Stepper Motor Working Principle: A Variable Reluctance Stepper Motor Working Principle consists of a single or several stacks of stators and rotors-stators have a common frame and rotors…
Parallel Magnetic Circuit: We have seen that a series magnetic circuit carries the same flux and the total mmf required to produce a given quantity of flux is the sum…
Magnetic Leakage and Fringing: Magnetic Leakage and Fringing - Figure 10.28 shows a magnetized iron ring with a narrow air gap, and the flux which crosses the gap can be…
Series Magnetic Circuit: A series magnetic circuit is analogous to a series electric circuit. Kirchhoff s laws are applicable to magnetic circuits also. Consider a ring specimen having a magnetic…
Magnetic Circuit Analysis: Magnetic Circuit Analysis - The presence of charges in space or in a medium creates an electric field, similarly the flow of current in a conductor sets…
Single Tuned Circuit: Consider the Single Tuned Circuit in Fig. 10.21. A tank circuit (i.e. a parallel resonant circuit) on the secondary side is inductively coupled to coil (1) which…
Series Connection of Coupled Inductors: Let there be two inductors connected in series, with self inductances L1 and L2 and mutual inductance of M. Two kinds of Series Connection of…
Inductively Coupled Circuits: Inductively coupled multi-mesh circuits can be analysed using Kirchhoff s laws and by loop current methods. Consider Fig. 10.17, where three coils are inductively coupled. For such…
