Conversion of Alternating Current into Direct Current by means of a Commutator

The process of conversion of alternating current into unidirectional current is made with help of a mechanical device called commutator which is attached tho the shaft of the machine and the armature coils.The most common of this is the split ring commutator.The figure below shows a split ring commutator.Look at the first figure. In the [...]

Direct Current Generators

Basic Type of Direct Current Machine The direct current machines are generally alternate current machines but equipped with a device called commutator which would convert alternating current into direct current under certain conditions.In the early stages the conditions for the commutator to work was so complicated so an idea of using homo polar machine came [...]
