What are the requirements of industrial development for micromotors in dental clinics?
Industrial development is one of the distinctive features of industrialization, but industrialization cannot be narrowly understood as just industrial development. Because industrialization is the core content of modernization, it is the process of transforming traditional agricultural society to modern industrial society. So what are the requirements of industrial development for micromotors in dental clinics?
1. Miniaturization
At present, the research of dental clinic micromotors is to optimize the structure of the existing dental clinic micromotors to improve the output characteristics, on the other hand, to explore new structures of dental clinic micromotors. Research on micromotors in dental clinics has made progress in three directions: electrostatic dental clinic micromotors, electromagnetic dental clinic micromotors and piezoelectric dental clinic micromotors. Among them, the electrostatic dental clinic micro-motor is driven by electrostatic force. The electrostatic force is a surface force, and its effect is relatively enhanced with the size reduction, but the friction and viscosity in the motor are also stronger.
Therefore, the electrostatic motor has a small torque and is difficult to apply. Electromagnetic dental clinic micromotors use traditional electromagnetic drive methods, using precision machining or IC technology to achieve miniaturization, and great progress has been made in the development of millimeter-level dental clinic micromotors. Piezoelectric dental clinic micromotors use friction as the driving force, and the negative impact of the size effect is small, and may become a promising micromechanical power source.
2. High precision
The transmission and processing of industrial machinery mechanism mainly comes from the mechanical performance of the motor, and its positioning function is directly related to the accuracy of the mechanical movement. Therefore, excellent motor positioning technology is a prerequisite for many industrial controllers. Since the common types of control motors include stepping motors, AC servo motors and DC servo motors, the positioning function of the servo motor is an important basic factor for the development of industrial machinery to automation. In recent years, the integrated circuit and electronic manufacturing industries have developed vigorously, and there is an urgent need for high-speed and precise motor point-to-point movement.
