An alternating three-phase voltage… The output of the alternator is taken form the stator. At the presence of this constant magnetic flux, rotor is rotated through the prime over. Oct 13, 2016 · This document provides information about the working principle and construction of an alternating current (AC) generator. DC Generator • A generator which produces direct current is called as a dynamo. 2. It has two main parts: a rotor and a stator. Thus the rotor and hence the field magnets are rotated in the direction of the prime mover. The rotor produces the main field flux. The rotor rotates inside the stator, and the field poles project onto the rotor body. 4CUH Slide No. The construction of the stator of an alternator is equal to the construction of the stator of an induction motor. Sep 13, 2017 · Alternator Construction video gives an brief explanation on main parts of alternator. According to Faraday's law of electromagnetic induction, whenever a conductor moves in a magnetic field, an EMF gets induced across the conductor. Dec 13, 2016 · Construction & Working principle of Synchronous Moto: We have seen the various features of three-phase alternator. Alternators are also known as synchronous generators. It consists of a field magnet that produces a magnetic field, an armature coil that rotates in this field, slip rings to carry the changing current from the rotating coil, and brushes that transfer this current to an external circuit.
