The Electric Motor and Generator are differentiated on various factors like the main principle of working or function of the motor and generator. Consumption or production of electricity, its driven element, the existence of the current in the winding. Fleming’s rule followed by the motor and generator. The Difference Between the Motor and the Generator …
The Equivalent Circuit of an Induction motor enables the performance characteristics which are evaluated for steady-state conditions. An induction motor is based on the principle of induction of voltages and currents. The voltage and current are induced in the rotor circuit from the stator circuit for the operation. The equivalent circuit of an induction motor …
An Isolated Induction Generator means that an induction machine can work as a generator even without an external supply system. A three-phase delta-connected capacitor bank is connected across the terminals of the machine as shown in the figure below. It provides a necessary excitation to the machine. The residual flux present in the machine provides …
The Polyphase Induction Motor is a motor whose stator contains a number of windings. They are greater than one horsepower or one kilowatt. The National Electrical Manufacturers Association (NEMA) has specified the motors according to the various classes, which are discussed below in detail. There are various applications of Polyphase wound rotor induction motors, Polyphase …
The induction Generator is also known as Asynchronous Generator. An Induction Machine sometimes is used as a generator. Initially, an induction generator or machine is started as a motor. At the starting, the machine draws the lagging reactive volt-amperes from the supply mains. The speed of the machine is increased above the synchronous speed by …

The basic feature of Pole Amplitude Modulation (PAM) winding is the layout, which is irregular. The windings are divided into two parts. The two parts are either connected in series or parallel. The directions of current in the two halves are either the same or opposite. The process of the current reversal is equivalent to …
Space harmonics fluxes are produced by the windings, slotting, magnetic saturation, inequalities in the air gap length. These harmonic fluxes induce voltages and circulate harmonic currents in the rotor windings. The interaction between the harmonic currents generated in the rotor and the harmonic fluxes results in the Harmonic torques, vibrations, and the noise. The air …
