Title: Split rings on a dc generator
Post by: shokstar on November 08, 2010, 09:23:18 pm

Whats the purpose of a split-ring commutator which is connected to a dc generator? Is it:

'As the coil is moved mechanically, a generated current will be produced, as the coil is turning in a magnetic field. The current produced will be AC, and hence, a split ring is used to invert the output every half turn, similar to their purpose in a motor, however in this case, the split ring is converting AC current into DC current, the opposite to the case in a motor, thereby producing a DC output'

Im not 100% sure if that is correct. Thanks in advance  :D
