US 12,401,297 B2 · Drive assembly, motor, and terminal

Abstract

This application relates to a drive assembly, a motor, and a terminal. The drive assembly includes a stator and a rotor. The stator includes an excitation part, a vibration part, a first fixed part, and a pushing part. The vibration part is connected to the excitation part. The first fixed part is connected to the vibration part, and the vibration part is located between the excitation part and the first fixed part along a first direction L. The pushing part is connected to the vibration part and the rotor. The excitation part is capable of vibrating, and the excitation part is capable of driving the vibration part to act. Under limiting by the first fixed part, the vibration part is capable of vibrating at least along the first direction L and a second direction W.
