Abstract

The embodiment of the invention relates to the technical field of linear motors, and discloses a linear motor. The linear motor comprises a shock absorber, the shock absorber comprises a second air cylinder and a second piston located in the second air cylinder, an inner cavity of the shock absorber is divided into a second compression cavity and a second back cavity through the second piston, and the second compression cavity is communicated with a first back cavity of the linear motor, so that pressure fluctuation existing in the first back cavity drives the second piston to do corresponding linear reciprocating motion. The linear motor provided by the embodiment of the invention is simple in structure, good in damping effect and convenient for practical application.

Description

Technical field [0001] The present invention relates to the field of linear motors, and more particularly to a linear motor. Background technique [0002] The linear motor is widely used in the thermal sound engine, the hot sound refrigerator, the Stirling generator, the Stirling refrigerator, and the vessel refrigerator. Since there is a moving member in the motor, the motor will generate vibration, even with the opposing motor structure, it will still be vibration because the machining of the opposing motor is not completely consistent. [0003] In order to achieve the minimum vibration of the motor, one method is to install a passive damper on the motor housing, the passive damper utilizes the vibration on the housing as a drive, and its motion phase is opposite to the vibration of the housing, thereby achieving the vibration Effect. Since passive damping depends on the vibration of the outer casing as a drive, the housing vibration cannot be completely eliminated. Another way...
