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.

MC3 LED BRUSH MICROMOTOR

Thanks to the turns of its coiled rotor, the MC3 operates perfectly even the lowest speeds

Bien-Air LED Lighting

For the LED light on these Micro-Series micromotors, Bien-Air has gone to great lengths to combine the best components available with application techniques to guarantee unique levels of performance and reliability. Bien-Air LED lighting offers unmatched working comfort. Its intensity can be adjusted from 0 to 38,000 lux.
It significantly improves visibility of the working area and diffuses a perfectly white and natural light.
Its 4500 K colour temperature is perfect for providing a realistic rendering of the dentine, the pulp or the gingiva, thereby facilitating diagnosis. The perfect encapsulation of the LED insealed optical glass guarantees its resistance to many years of repeated use.
