DC Generator Vs Alternator

Apr 30, 2018· DC Generator Vs Alternator , In terms of design, a DC generator is the simpler of the two In fact, a DC generator can be used as a DC motor by applying power to the shaft, while the opposite is also true -- turn the shaft of a DC motor, and it will act as a generator This is one of the greatest benefits of a generator: It will produce.

PMG construction manual

This manual describes how to build a 'permanent magnet generator' (PMG) We can also call it an 'alternator', because it generates alternating current (AC) It will not generate 'mains voltage' or 'utility power' AC It generates low voltage, 'three phase' AC, and then changes it into 'direct current' (DC) for charging a 12 volt battery.

Working Principle of Alternator

An alternator operates on the same fundamental principle of electromagnetic induction as a DC generator The working of an alternator is based on the principle that when the flux linking a conductor changes, an emf is induced in the conductor Like a DC generator, an alternator also has an armature winding and a field winding.
