Title:
LINEAR MOTOR
Document Type and Number:
WIPO Patent Application WO/2022/062038
Kind Code:
A1
Abstract:
A linear motor (10), which comprises a housing (100), an elastic member (200), an oscillator assembly (300), and a stator assembly (400), wherein the stator assembly (400) comprises a coil (410), the coil (410) and the oscillator assembly (300) are arranged spaced apart from each other, the coil (410) comprises a first arc segment (411) parallel to a first plane and a second arc segment (412) that bends and extends from an end part of the first arc segment (411), the second arc segment (412) is parallel to a second plane, the first arc segment (411) and the second arc segment (412) are connected end to end to form a ring, the first plane and the second plane intersect, and the first plane and the second plane are respectively located on two adjacent sides of the oscillator assembly (300). Once the coil (410) is energized, the first arc segment (411) can generate a first action force parallel to the first plane, and the second arc segment (412) can generate a second action force parallel to the second plane, which then enable the coil (410) to generate an oblique driving force synthesized by the first action force and the second action force, thereby increasing the magnitude of the oblique driving force for driving the oscillator assembly (300) to vibrate, while reducing the structural complexity of the linear motor (10) and the number of the coils (410) and magnetic steel (310).
