Commutator serves as switch,
namely to connect coil anchor briefly. Commutator form of a ring fitted on end
coil anchor.If coil anchor rotatory; then ring sides to revolve.Because coil be
in magnetic field, shall arise voltage commuting between sinusoidal.If coil has
rotating half round, brush will close the aperture of a ring so that voltage be
zero.Because ring spinning. , Then gap will open again and arising voltage
again.If period voltage same with a period gyrations ring, voltage arises
voltage direct current wave full.
The commutator serves as a
rectifier mechanical, with sawn-off form a cooperation called comutation.
Rectifier that produces better, then the commutator used there are
many.Therefore every segment / hemisphere commutator no longer is partly,
cylindrical form but it was shaped lempeng-lempeng.Among segments each plate /
commutator guiler an insulating material.An insulator used determine class of
machinery based on capability of temperature that arise in the machine.So beside
as an insulator against electric insulators used to be able to heat.
