why commutator is attached with only dc macine
Answers were Sorted based on User's Feedback
Answer / chinna
commutator is unit which converts AC voltage into
Unidirection DC Voltage. The voltage generated in the DC
machine is in alternating nature. Because of this reasion
commutator is attached with DC machine.

Answer / amirtha
becoz to get dc output we are conneting commutator.from the
armature commmutator collets the ac current and convert it
to dc.tnis is not needed in ac machine

Answer / dany
Commuttor is vital part in especially DC machines.
it is the place where commutation will be take
place ,commutation means reversal of current direction in
current carriying armature coils or simply conversion into
DC .
SINCE in AC machines there is no need of DC output we dont
use commutators

in dc generator it makes bidirectional current to
unidirectional current
in dc motor it makes unidirectional torque

Answer / zakeer
it collects current from windins and the max torque of dc motor is is limited also it gives unidirectional torque

How can we design a HVAC Plant room which includes AHU,FCU,Chillers,Cooling towers, Pumps etc & how will they work? any Drawing if possible?
When batteries are connected in series the voltage increases but the current remains unchanged, how can this be? When you consider ohm's law. i.e. If voltage increases, current increases, providing resistance remains the same.
