Abstract

This invention relates to axis magnetic column permanent line motor in relative line motor, wherein, several permanent magnetic rings and several rings are covered on secondary axis with each one as axis and with tube initial iron center inner wall opened with ring tanks; multiple ring tank is imbedded with rivet sets setting inside tube iron center; tube initial iron center is composed of several iron core slices with each opened with multiple beams.

Description

Technical field [0001] The invention relates to the technical field of permanent magnet linear motors. Background technique [0002] The permanent magnets on the secondary of the traditional cylindrical permanent magnet linear motor are all magnetized radially, which makes the iron core of sufficient thickness exist on the secondary to form a closed magnetic circuit, which makes the secondary mass relatively large , And also bring secondary iron loss, especially when the secondary actuator will affect the response speed of the mover. In addition, usually limited by the process, the primary iron core punching is not easy to be made into a radial lamination type, and the general axial lamination is greatly affected by the eddy current, which is prone to large core loss. Summary of the invention [0003] In order to solve the problem of large mass and large iron loss in the secondary side of the traditional cylindrical linear motor using radial magnetization, especially when the se...
