Micro-motor market in dental clinics
Micromotors in dental clinics are micromotors, also called small motors. They are a new type of driving device that integrates ultrasound, vibration, materials, tribology, electronics and control science into a multidisciplinary technology. The motor uses the inverse piezoelectric effect of piezoelectric materials to make a new type of driver. It consists of a stator, a rotor, and a mechanism for applying pre-pressure. Applying an ultrasonic frequency alternating voltage to piezoelectric ceramics can generate ultrasonic vibration on the surface of the stator, and the rotor is driven by the friction between the stator and the rotor.
Micro-motor products for dental clinics are indispensable basic products that are widely used in the cutting-edge of national defense, biomedicine, semiconductor and other fields. With the continuous improvement of people's living standards and the progress of industrial economy, as well as the continuous expansion of the application field of micro-motors, the market capacity of the world's micro-motors is advancing rapidly.
Compared with electromagnetic motors, the main features of ultrasonic motors include:
1. High torque and low speed, no reduction mechanism required;
2. High energy density, up to 3-10 times that of electromagnetic motors;
3. The response speed is fast, only in the order of ms;
4. High positioning accuracy;
5. No electromagnetic interference;
6. Because it is driven by friction, it has self-locking function.
