OPERATION MECHANISM AND POWER SWITCH DEVICE PROVIDED WITH SAME

摘要

The purpose of the invention is to provide a high speed high response power switch device operation mechanism that has an indispensable function and to provide a power switch device provided with said operation mechanism. The invention is provided with an outer side permanent magnet (31) row an inner side permanent magnet (32) row an inner side pipe (38) an outer side pipe (39) a three phase coil (33) an output ring (34) and a power supply line (33a). The outer side permanent magnet (31) row members adjoin such that the magnetic poles thereof rotate up to 90 degrees at a time. The magnetic poles of the inner side permanent magnet (32) row comprise a magnetization vector radial direction component of the same orientation as the outer side permanent magnet (31) row and a magnetization vector axial direction component of the opposite orientation. The outer side permanent magnet (31) row and the inner side permanent magnet (32) row are fixed facing each other such that the magnetization vector radial direction components thereof have the same orientation. The three phase coil (33) lies between the outer side permanent magnet (31) row and the inner side permanent magnet (32) row with a set clearance.
