What is the working principle of micromotors in dental clinics?
Micromotors in dental clinics developed rapidly in the 1980s and are a new type of micromotors based on piezoelectric effect and ultrasonic vibration. It breaks through the principle of electromagnetic motor and has the advantages of small size, high torque, precise structure and fast response speed. Micromotors are currently widely used in fields such as intelligent robots, precision instruments, medical equipment, aerospace and optical lenses.
What is the working principle of micromotors in dental clinics? To put it simply, it uses the characteristics of piezoelectric material that the input voltage will produce deformation, so that it can generate mechanical vibration at ultrasonic frequency, and then through the design of friction drive mechanism, the ultrasonic motor can be rotated or linear like an electromagnetic motor式动。 Type mobile.
Normally, when the electromagnetic motor is running, we feel that there is noise. This is because the internal structure of the motor vibrates, and the vibration frequency is just within the frequency range that our ears can feel. The vibration frequency of the ultrasonic motor is designed to be outside the range that the human ear can hear, so when it is running, we don't feel any sound, so it feels very quiet. This is a very important feature of the ultrasonic motor.
