Abstract

The invention discloses a linear rotary voice coil motor, which includes a casing, a stator and a mover arranged inside the casing, the stator includes a linear motion winding, a rotary motion winding and an iron yoke installed on the inner wall of the casing, and the movable The sub includes a bracket shaft, a non-magnetic rubber ring sleeved on the bracket shaft and a permanent magnet installed on the non-magnetic rubber ring. Installed in the casing, the linear motion winding, the rotary motion winding and the iron yoke are respectively arranged around the mover, the rotary motion winding includes a multi-turn first coil wound on the iron yoke, and the linear motion winding includes a cylinder wound A multi-turn second coil with a shape structure. The linear rotary voice coil motor aims to solve the technical problems in the prior art that the motor is difficult to take into account the two-degree-of-freedom movement and is easy to be damaged and magnetic flux leakage.

Description

technical field [0001] The invention belongs to the field of motors, in particular to a linear rotary voice coil motor. Background technique [0002] The motor mainly includes a stator and a mover (or mover). In the prior art, most of them are independent linear motors or rotary motors. There are few motors that can take into account both types of motion, and magnetic flux leakage is also prone to occur in the motor. The movers are also not well protected. Therefore, with the development of motor technology, it is imperative to explore and research its superior performance. Contents of the invention [0003] (1) Technical problems to be solved [0004] Based on this, the present invention proposes a linear rotary voice coil motor. The linear rotary voice coil motor aims to solve the technical problems in the prior art that the motor is difficult to move with two degrees of freedom and is easily damaged and prone to magnetic flux leakage. [0005] (2) Technical solution ...
