Dental micromotor MC2

electricwith LED light

The MC2 is the most widely used electric micromotor in the world. Prized and recommended for its reliability and endurance, it has been proving its worth for many years. With a rotation speed ranging from 60 to 40,000 rpm, the performance it offers is remarkable. The MC2 micromotor: Swiss-Made design at an attractive price. Also available in MicroSeries version with short nose and LED light with adjustable intensity. Now also available as an upgrade set for your old MC2 Isolite 300. HOW DO THE MC2 CARBON BRUSH MICROMOTOR WORK? All electric micromotors are made up of a rotor and a stator. The rotation is generated by magnets interacting with an electric current flowing through a wire coil. In the case of brush micromotors, the coils are located on the rotor. Electrical power is supplied to the coils through carbon brushes located on the stator. The electrical current in the coil interacts with the magnets of the stator, thus generating rotation. COMPLEXITY OF BRUSH MICROMOTORS Complex mechanical design (rotor: multiple windings, collector and brushes, stator: permanent magnet). The brushes wear out so they must be regularly replaced (approximately 18-24 months in a dental micromotor). The carbon dust from the brushes disperses in the micromotor and can reduce the life of the micromotor bearings. The carbon brushes can cause interference with other electronic devices because of their constant interaction with the electrical components in the micromotor. The carbon brushes cannot be washed or sterilized as they absorb moisture generated from an air compressor.
