Title:
硬磁性物体、および磁気ベクトルの方向と位置を調節する方法
Document Type and Number:
Japanese Patent JP4271030
Kind Code:
B2
Abstract:
The invention relates to a magnetically hard object and to a method for adjusting a magnetic vector of a magnetically hard object. The aim of the invention is to provide a magnetically hard object and a method for producing the same, said object having a desired resulting magnetic vector which moves within a pre-determined tolerance range, without influence from an external magnetic circuit. Furthermore, the magnetically hard object is to have a higher maximum energy density in relation to prior art. According to the invention, a magnetically hard object having a magnetic vector which moves in the open magnetic circuit, to a large extent within a pre-determined tolerance range, consists of at least one magnetically hard moulded part (1) and at least one other moulded element (11) which are combined in such a way that a pre-determined direction and position of the magnetic vector of the magnetically hard object are achieved by forming, combining and orienting the moulded part (1) and the moulded element (11). The magnetic vector of the magnetically hard object is the resulting magnetic vector of the magnetic vectors (4, 14) of the magnetically hard moulded part (1) and the moulded element (11).
