PREMIUM QUALITY
Originating in the early electrical engineering era, mica commutators have revolutionized electric motors and generators.
Axim Mica’s AX-COMMUTATOR Muscovite & Phlogopite sheets are hard, dense mica plates employed in segments, separators, and spacers, offering excellent electrical and thermal properties, as well as mechanical strength.
Despite their need for precise installation, mica commutators emerge as the superior choice. They vastly outperform other materials in thermal and electrical insulation, making them essential in today’s high-demand electrical applications.
Range: 0.20mm – 2.0mm
Can be sawed, sheared, and punched into custom shapes, with superior uniformity enabling automatic feeding and stacking in high-speed assembly operations.
Mica bars electrical shorts dead in their tracks, ensuring smooth motor and generator operations.
High-speed applications meet their match in mica commutators, designed for stability and peak reliability.
We start with premium-grade mica, known for its exceptional electrical insulation and thermal properties.2. Grinding into Fine Powder: The selected mica is then ground into a fine powder, providing the base material for the commutator.
This mica powder is layered, under pressure, with a resin binder to form sheets that will become the commutator segments.
These mica-resin sheets are precisely cut and shaped into the commutator segments.
The segments are expertly assembled, with insulating properties between each, onto a shaft, forming the final commutator ready for installation.
Our AX-THERM Muscovite & Phlogopite mica sheets consist of 85-90% high-grade Muscovite or Phlogopite that is impregnated with a high temperature resistant silicone resin.
In commutators, mica serves as an insulating material between the copper segments. Its excellent electrical insulation properties prevent short circuits, ensuring efficient and safe motor operation.
Mica in generators functions as an insulating layer within the commutator and between windings. This protects against electrical leakage, enhances durability, and ensures the generator runs smoothly under high voltage conditions.
Mica is widely utilized in electrical applications for its superior insulation properties. It’s employed in capacitors, high-voltage equipment, and thermal insulators, providing stability and safety across various conditions and temperatures.
Mica separators are used in commutators to electrically insulate each copper segment. This separation is crucial to prevent short circuits and maintain the integrity of the electrical path, ensuring the commutator functions efficiently.
