Title:
LINEAR MOTOR
Document Type and Number:
WIPO Patent Application WO/2022/062017
Kind Code:
A1
Abstract:
A linear motor, comprising a housing (100) having an accommodation space (101), an oscillator component (300) suspended in the accommodation space (101) by means of an elastic member (200) and reciprocatingly vibrating along the vibration direction, and a stator component (400) fixedly connected to the housing (100), wherein the elastic member (200) can provide the restoring force for the oscillator component (300), and further comprising a friction member (600). According to the linear motor, the friction member (600) is arranged between the oscillator component (300) and the housing (100). The friction member (600) is fixedly connected to one of the oscillator component (300) and the housing (100), and is used for providing damping for the oscillator component (300) in a form of friction force in the vibration process of the oscillator component (300) to replace a damping member to provide damping for the oscillator component (300). The problems of higher manufacturing cost and easy aging of materials caused by the use of the damping member are avoided, and thus the performance of the linear motor is improved.
