Mica Molded Commutators
Ruby Mica® Commutator Segments AV is made by depositing highly-flexible, thin films of high-quality muscovite mica splittings on top of each other till the required thickness is attained. These rigid sheets are fully heat and pressure-cured using alkyd vinyl resin as a binder.
Ruby Mica Commutator Segments MP is made by combining phlogopite mica paper with an epoxy resin binder. These rigid sheets are fully cured under high specific-heat and pressure.
A great deal of emphasis is given to the segment-hardness and precise thickness. The sheets are finely ground and passed through stringent thickness-testing both online and offline to ensure their conformation to the norms.
These commutator segments are highly customizable and therefore can be punched or machined to desired shapes and sizes.
