Title:
ARMATURE STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2019/184199
Kind Code:
A1
Abstract:
An armature structure (100), relating to the technical field of armature structures. The armature structure (100) comprises: an armature body (20), comprising a fixing portion (21) and a conducting portion (22), the fixing portion (21) being connected to the conducting portion (22); and a U-shaped magnetic conductive element (10), comprising a first sidewall (11) and a second sidewall (12) which are provided opposite to each other and a bottom sidewall (13), one end of the first sidewall (11) being connected to one end of the bottom sidewall (13), and one end of the second sidewall (12) being connected to the other end of the bottom sidewall (13),such that the first sidewall (11), the second sidewall (12) and the bottom sidewall (13) form a U-shaped structure, the U-shaped magnetic conductive element (10) covering the fixing portion (21), the fixing portion (21) being fixed to the other end of the first sidewall (11) and the other end of the second sidewall (12), such that the opening of the U-shaped magnetic conductive element (10) is enclosed by the fixing portion (21). Thus, in the armature structure (100), the U-shaped magnetic conductive element (10) is fixed to one end of the armature body (20) and form a square frame shape or an annular shape in an enclosed manner, reducing the overall size of the armature structure (100) and lowering the material cost while ensuring that the armature structure (100) can operate normally.
