Miniature motors, precision-engineered for accuracy, achieve smaller, lighter, and thinner designs while maintaining the same output torque. There are numerous advantages to miniature motors, so let's explore them now!

1. Low-speed, high-torque: In small motors, the amplitude of ultrasonic vibration is generally no more than a few micrometers, and the vibration speed ranges from a few centimeters per second to a few meters per second. In the absence of sliding, the speed of the rotor is determined by the vibration speed, so the motor's rotation speed is typically low, ranging from a dozen to a few hundred rotations per minute.

2. Fast response time, excellent control characteristics: The micro motor is driven by friction, with the moving body being lightweight and having low inertia. This results in a rapid response time, with start-up and stop times on the millisecond scale. Consequently, it can achieve high-precision speed and position control.

3. No Electromagnetic Interference: The miniature motor has no poles, making it immune to electromagnetic induction. Additionally, it does not generate electromagnetic interference externally, making it particularly suitable for working environments in strong magnetic fields. A small motor is also a suitable choice in environments with stringent EMI (electromagnetic interference) requirements.

4. Flexible Form, Simple Structure: The drive part of the ultrasonic motor can be designed flexibly according to needs, featuring a simple structure.
