Mica Commutators

Mica Commutators

For commutators to work properly, a solid insulator is needed to separate the components within the commutator.  Thanks to the thermal and electric insulation capabilities of mica, it is a great choice to use as material in commutators.


AX-COMMUTATOR M & P sheets are hard, dense mica plates used in segments, separators and spacers. They exhibit good electrical & thermal properties and mechanical strength. AX-COMMUTATOR M & P sheets can be sawed, sheared and punched into customized shapes. Its superior uniformity enables automatic feeding and stacking within high speed assembly operations. AX-COMMUTATOR M & P sheets are used within a wide range of small and medium size commutators for all kind of household applications, industrial equipment and power tools.




AX-COMMUTATOR M & P sheets consist of minimum 90% Muscovite alternatively Phlogopite impregnated with a specially developed epoxy resin.


Supply form:


Thickness: 0.20 – 2.00 mm
Size: 1000 mm width, 600 mm or 1200 mm length
Customized strips or punched parts according to customers’ drawings and/or requirements.



AX-COMMUTATOR M & P sheets can be easily punched or sheared. Tools for punching precise parts should be provided with spring loaded hold-down plates.
