Magnetic Circuit Calculations: Normally magnetic circuit calculations involve two types of problems. In the first type of problem it is required to determine the excitation (mmf) needed to establish a desired flux or flux density…
BH Curve Relationship (Magnetization Characteristic) for Ferromagnetic Material: In free space (also nonmagnetic materials), the permeability μ0 is constant so that BH Curve Relationship is linear. This, however, is not the case with ferromagnetic materials used…
Magnetic Field Equation: The exact description of the Magnetic Field Equation Basics is given by the Maxwell's equations and the constitutive relationship of the medium in which the field is established. Such description apart from…
Recent Trends in Electric Machines: Recent Trends in Electric Machines are neural networks, Artificial Intelligence, expert system, fibre communications and integrated electronics, hot superconductors and other new ceramic conducting and dielectric materials, magnetic levitation etc. should…
Types of Rotating Electric Machine: The Types of Rotating Electric Machine are namely the dc machine, the polyphase synchronous machine (ac), and the polyphase induction machine (ac). Three materials are mainly used in machine manufacture;…
Electric Generator Diagram: Electric Generator Diagram - Electricity does not occur naturally in usable form and it also cannot be stored in usefully large quantities. Therefore, it must be generated continuously to meet the demand…
