Document Type and Number:
WIPO Patent Application WO/2023/135894
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a linear motor in which the reduction of thrust and the rise of temperature are suppressed. The linear motor according to the present invention has an armature 8 having teeth 2 and coils 5 provided on the teeth 2 and permanent magnets 10 provided on the outer circumferential side of the armature 8, wherein the armature 8 and the permanent magnets 10 move relative to each other. The teeth 2 are provided with slits 7 for increasing the resistance value of the path of eddy current flowing through the teeth 2. The slits 7 are disposed so as to extend from the inner circumferential side of the teeth to the outer circumferential side thereof.
