Abstract

A driving apparatus comprises a stator (21), a rotor (22) and a deformation connector (23). The rotor is connected to the stator through the deformation connector. An external driving force drives the deformation connector to have deformation so that the rotor changes its position with respect to the stator. Under the condition that no external driving force is applied, the deformation connector remains at a force balanced position (x0). The force on the deformation connector comprises a deformation force (F1) of the deformation connector and a first primitive force (F2) in opposite direction to the deformation force (F1). Also provided is a device fabrication method. Because the deformation connector keeps balance under the effect of the deformation force and the first primitive force, a small external driving force is required when the driving apparatus operates near the balance point, thereby reducing power consumption.

Description

technical field [0001] The invention relates to the electromechanical field, in particular to a driving device and a device manufacturing method. Background technique [0002] The driving device is a type of device for energy transmission and / or conversion, such as a motor. Due to the reversibility of the generator and the motor, the motor referred to in this paper includes both the generator and the motor, or a reversible motor with dual functions. There are many types of driving devices, but they usually have a stator and a mover. In this paper, the moving part in the device is called the mover, and the relatively fixed part in the device is called the stator. In some driving devices, the mover and the stator are connected together through a deformable joint. A simple example is a linear voice coil motor (VCM, Voice Coil Motor), which is used in the optical field, such as in the autofocus module of a mobile phone camera. , has been widely used. [0003] The basic structu...
