Title:
LINEAR MOTOR
Document Type and Number:
WIPO Patent Application WO/2022/047867
Kind Code:
A1
Abstract:
A linear motor, comprising a sliding body (100), a magnetism generation mechanism (200) and one or more magnetic members (300); the magnetism generation mechanism (200) is magnetically fitted with the one or more magnetic members (300) and is used for driving the sliding body (100) itself to move; the one or more magnetic members (300) are arranged in the sliding body (100) at intervals in the movement direction of the sliding body (100); and a first side (310) and a second side (320) which correspond to the movement direction of the magnetic members (300) are both arc-shaped sides, the convex direction of the first side (310) is consistent with the convex direction of the second side (320), and the radian of the first side (310) is consistent with the radian of the second side (320). The linear motor can effectively reduce the thrust ripple when the sliding body (100) moves by itself, ensuring the operation effect of the linear motor.
