- 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.
Features:
- Greater Power and More Torque. A major attribute of Bien-Air micromotors is their elevated power output with constant torque for swift and effortless use.
- Accurate Command. The proprietary Smart Logic electronic control lends Bien-Air micromotors a step-less, vibration-less rotation for the most meticulous and precise dental work.
- Compact and Lightweight. Bien-Air micromotors are significantly shorter and lighter than conventional models. This results in optimal grip and balance as well as reduced hand fatigue.
- Maintenance-Free. Bien-Air micromotors ball bearings are greased for life making post-usage lubrication expendable. Built to withstand repeated sterilization cycles, the strictest hygiene standards are upheld.
- Easy and economical to maintain.
