Question

How does the split ring commutator work in a d.c. motor, and the slip rings in a a.c. generator??? i'm confused between their functions :P

Answer 1

its easy

Answer 2

Split rings in a DC motor reverse the direction of current

Answer 3

in ac we use slip ring commutator

Answer 4

let me explan

Answer 5

In AC generator, Slip rings convert Ac to DC

Answer 6

during first half cycle of input ..current flows throgh the commutator through the slip ring

Answer 7

but in next half cycle the direction of current reverses

Answer 8

split rings in ac generator are meant for continually direction changing current in OUTPUT, while its in reverse...

Answer 9

as input current is ac

Answer 10

that is current of opp polarity gets induced in the same brush dush during each half cycle

Answer 11

hence we get ac from it

Answer 12

this is not the case in a dc motor

Answer 13

here we need dc as output

Answer 14

so we use split ring commutator

Answer 15

here during each half cycle one split ring changes its contact to other brush

Answer 16

resulting in unidirectional current flow

Answer 17

and thus unidirectional torque

Answer 18

split ring is use in dc motor to make the direction of
current uniformly . the rotor of generator rotate by 360
degree . as per principle generating wave be sinusoidal for
180 degree +ve & 180-360 degree -ve .so to make the
direction of waveform unidirectional the split ring rotate
after each interval of 180 degree .

the difference between slip ring & split ring is slip ring
are stationary . & split ring rotate after 180 degree
