Magnetic levitation acoustic motor is used in the driving device of car window, which can make its advantages of small size, low speed and high torque play incisively and vividly. It can also be used on maglev trains. In order to levitate the train on the track, a strong magnetic field is generated by superconducting current, which requires a large torque and a driver with good control performance, which is the most suitable for USM.

The operating characteristics of motors in low temperature and vacuum conditions are very important for the development of aerospace. Magnetic levitation acoustic motor has the advantages of simple structure, light weight, no magnetic field interference, no lubrication under vacuum, electromagnetic motor does not have in the field of aerospace.

In late 1995, NASA's Jet Propulsion Laboratory first used the linear magnetic levitation acoustic motor in a multi-function crawl system for inspection of the outer bulkheads of spacecraft with a load-to-dead weight ratio of 10:1. By using the characteristics of low speed, high torque and high precision, Mars ARMⅱ is similar in structure to Mars ARMⅰ, but its weight is reduced by 40% after the magnetic levitation acoustic motor is used to replace the brush DC motor on the lightweight robotic Arm used by NASA for the Mars rover. The main reason is that the magnetic levitation acoustic motor can be directly driven. In addition, the working space can be greatly reduced. For example, the size of the Filter wheel on NASA's Calileo spacecraft is reduced by four times before and after the use of magnetic levitation acoustic motor.

Based on its flexible driving mode, two kinds of linear magnetic levitation acoustic motor have been developed by Japan Space Research Institute for extension and contraction of space extension structures. The United States and France used the measurement and control system for missiles by using the characteristics of fast response of magnetic levitation acoustic motor. By virtue of its simple structure and miniaturization, the micro magnetic levitation acoustic motor has been developed in Japan for use in the field of microsatellite. In addition, Japan and the United States and other countries are conducting various research on magnetic levitation acoustic motor for aerospace and other military fields. Thus, magnetic levitation acoustic motor with its large torque, high weight ratio, fast response, high precision and power off self-locking characteristics, will be in aerospace and other military fields by more and more attention.

Magnetic levitation acoustic motor has high rigidity and high positioning accuracy. It can be used for fixed point transmission of tool drive and control device and workpiece. Such as precision machine feed mechanism, tool wear scheduling device, micro electric discharge machine processing device, workpiece accurate positioning and clamping, tightening device and fixture rapid adjustment. 【 Application of Industrial Machine tools 】

Biomaterial micro operator, measuring equipment, micro nozzle, impact generator, kidney stone breaking treatment machine, tracheal ultrasound scanner. Many scientific instruments and medical instruments will produce strong magnetic fields or have strict requirements on electromagnetic interference, while magnetic levitation acoustic motor can avoid these problems, so it can be used to drive the equipment in the nuclear magnetic resonance environment. [Applications in Medical and biological fields]

Because of the quiet, small size and other advantages of magnetic levitation acoustic motor, it can be used in the use of compressors, and has a wide range of applications in the field of home appliances. Traditional motor drive due to the intermediate link, there is an inevitable cumulative error, and magnetic levitation acoustic motor control performance is good, small size, can be used for precision control, such as electronic watches; At the same time, it can be used for IC, LSI and other CNC machines, PCB processing, detection, wafer construction arrangement, welding, packaging and so on.
