Answer / seema

hey there,, i am in year 12 in one of the school In
Brisbane,, i guess i this is what i learn t at school..in
Physics Class.

A split rind commutator is a special switch assembly on the
rotating coil shaft that allows the direction of the current
through the coil to be reversed every 180 degrees .

Answer / siva.e

A commutator consist of atleest three segments.

In dc motors we supply dc to the armature.The function of
the commutator is to make the direct current to reversal
current due to this reversal current motor torque is high.

Answer / dipak

in dc motor commutator work as a connector.

Answer / ram

in motors it is used to produce a alternating flux with a
uniform dc source

Answer / kavila

It's a mechanical rectifier that converts the generated
alternating voltage to direct voltage at the terminals.

Answer / rasoul

reverse the direction of the Current

Answer / ranjith

in a dc motor dc current is converted into ac as input is dc and commutator serves the purpose of both ac to dc and dc to ac

Answer / ramesh

IN dc motor they used to give supply to coils as ac current and in the dc generator they used to collect the current adthe ac.

Answer / sethabela p.k

the function of a commutator in a dc
motor is to keep the torque of a
motor from reversing everytime the
motor rotates

Answer / karthick

To produce unidirectional torque in the rotor, We have commutator in DC Motor

Can earth resistance be measured without connecting the earth electrode? and should earthing connections be disconnected What is the effect of connecting two cables of different sizes in parallel with supply? Thanks in Advance. I am intrested to get in touch with some tecnocrats/engineers,my mail i.d is : hiremathvijay@rediffmail.com
