Title:
ELECTROMAGNETIC ACTUATOR
Document Type and Number:
WIPO Patent Application WO/2016/181551
Kind Code:
A1
Abstract:
A stator core is magnetically divided into a plurality of divided cores (4, 5) so as to increase the magnetic resistance of a magnetic path linking across a coil (6), wherein, when the divided cores (4, 5) are magnetically connected by means of a projection (82) of a plunger (8), a magnetic flux of a permanent magnet (7) flows through the magnetic path. Accordingly, the magnetic resistance of the magnetic path linking across the coil (6) rapidly changes due to the positional relationship between a gap between the divided cores (4, 5) and the plunger (8), whereby the magnetic flux flowing through the magnetic path rapidly changes, producing a large inverse induced voltage.
