What are the advantages of micro motor compared with traditional electromagnetic motor

The traditional electromagnetic motor has been developed for many years, whether in theory, design method or manufacturing technology has reached a very perfect degree.

Due to the limitations of its working principle and structure, it is difficult to meet the requirements of small volume, large torque, low noise and anti-interference proposed by the current micro intelligent robot, precision instrument, precision machinery and so on.

Micro motor in motor products, with small volume, high precision, fast response time, large torque, low noise, anti-overload and other advantages are widely used in many industries, micro motor to adapt to unconventional environment, so what are the advantages of ultrasonic motor?

It breaks through the traditional concept of electromagnetic motor, without pole winding and magnetic circuit, does not rely on electromagnetic interaction to convert energy, but uses the inverse piezoelectric effect of piezoelectric ceramics and ultrasonic vibration, converts the micro deformation of stator into the macro motion of rotor or actuator through resonance amplification and friction coupling.

In particular, the micro motor has the characteristics of light weight, simple structure, low noise, low speed and large torque, and can directly drive the load. It does not need gear change mechanism to reduce the speed, avoiding the vibration, impact and noise caused by the use of gear change mechanism. It can be said that ultrasonic motor technology is one of the high-tech in today's world.
