Like any other electric micromotor, brushless micromotors consist of a rotor and a stator.
Unlike the brush micromotor, the rotor consists of a permanent magnet, while the coils are mounted to the stator.
The mechanical switching function, implemented by the brush and collector combination in a carbon brush-type micromotor, is replaced by a sophisticated electronic drive that became possible only with the development of high-speed and powerful microprocessors.
The electronic drive creates a rotating electric field in the stator that interacts with the permanent magnet.
Bien-Air's new generation Micro-Series models ally innovation with compact design, resulting in improved power and maneuverability.
Up to 30 percent shorter and 23 percent lighter than traditional models, they have an easy grasp that allows for optimal work comfort with less strain on the hand, arm, and shoulder. A Bien-Air electric micromotor reduces noise levels by 2 compared to an air turbine.
This greatly decreases patient anxiety and discomfort and allows the dentist to work more efficiently.
It also vibrates considerably less.
This offers greater cutting precision and a smoother finish.
