Magnetic Properties of Materials: Magnetic Properties of Materials - From the magnetic point of view a material is classified according to the nature of its relative permeability (μr). All nonmagnetic materials are classified as paramagnetic…
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…
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…
Load Commutated Chopper Circuit: In this method of Load Commutated Chopper Circuit, the load current flowing through the thyristor is made to become zero while the motor current is conducted by the free-wheeling diode. Figure…
Isolated Induction Generator: An Induction Machine can also work as a generator even if external power supply not available and it is called Isolated Induction Generator. An Isolated Induction Generator feeding a load is shown…
Inverted Induction Motor: In a wound rotor induction machine the three-phase supply can be given to the rotor windings through the slip rings and the stator terminals can be shorted (see Fig. 9.68). Such a…
Introduction to Induction Machine | Use of Induction Motor: The Introduction to Induction Machine is an important class of electric machines which finds wide applicability as a motor in industry and in its single-phase form…
Introduction of DC Motor: Introduction of DC Motor is constructed in many forms and for a variety of purposes, from the 3-mm stepper drawing a few μA at 1.5 V in a quartz crystal watch…
Insulated Gate Bipolar Transistor (IGBT): An Insulated Gate Bipolar Transistor (IGBT) is basically a hybrid MOS-gated turn on/off bipolar transistor that combines the features of MOSFET (voltage control features), BJT (fast acting features and high…
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. The Induction Motor Speed Control,…
