Basic conditions for the operation of micromotors in dental clinics
Micro-motor technology in dental clinics is a new technology that combines disciplines such as vibration, wave, tribology, dynamic design, power electronics, automatic control, new materials and new processes. So what are the basic conditions for running a dental clinic micromotor?
a. On the surface of the elastic body as the stator (the contact surface with the rotor), the vibration of the particle along the elliptical track must be excited;
b. There must be a certain coefficient of friction between the contact surface of the stator and the slider;
c. A certain amount of pressure must be applied to the contact surface.
Unlike traditional motors, dental clinic micromotors use electromagnetic cross force to obtain their motion and torque. The dental clinic micromotor uses the inverse piezoelectric effect of piezoelectric ceramics and ultrasonic vibration to obtain its motion and torque, and converts the microscopic deformation of the material into the macroscopic motion of the rotor through mechanical resonance amplification and friction coupling. In this new type of motor, piezoelectric ceramic material discs replace many copper coils.
