Advantages and applications of micromotors in dental clinics
Dental clinic micromotors are abbreviated as small motors. Unlike traditional motors, dental clinic micromotors have no windings and magnetic poles. They do not need to generate cloud power through electromagnetic action. Instead, they use the inverse piezoelectric effect of piezoelectric ceramics and ultrasonic vibration to transform the microscopic The deformation is converted into the macroscopic motion of the rotor through mechanical resonance amplification and friction coupling.
In which industries can micromotors in dental clinics be used?
1. Aerospace: Aerospace vehicles are often exposed to harsh conditions such as high vacuum, extreme temperature, strong radiation, and ineffective lubrication, and require strict system weight. Ultrasonic motors are the best choice for drivers.
2. Precision instruments: Electromagnetic motors use gearbox deceleration to increase torque. Due to the gear gap and return error, it is difficult to achieve high positioning accuracy. Ultrasonic motors can directly drive, and have fast response and good control characteristics. Precision instrumentation.
3. Robot joint drive: using an ultrasonic motor as the joint driver of the robot, the fixed and moving parts of the joint can be integrated with the stator and rotor of the ultrasonic motor respectively, making the whole mechanism very compact. Japan has developed a spherical ultrasonic motor, which solves many problems for the driving of multi-degree-of-freedom robots.
