Title:
ELECTROMAGNETIC ACTUATOR
Document Type and Number:
WIPO Patent Application WO/2016/047390
Kind Code:
A1
Abstract:
 There has been a need to realize an electromagnetic actuator in which the length of a magnetic core can be kept from increasing in the drive direction while ensuring electromagnetically produced drive force, and in which the magnetic core can be disposed in a partial circumferential-direction area. Magnetic cores (MB) of an electromagnetic actuator (1) have a pair of magnetic poles (9, 10) that are given opposite polarities by energizing a coil, the two magnetic poles (9, 10) are aligned in the magnetic pole arrangement direction (Y), which intersects the drive direction (X); the plurality of magnetic cores (MB) are arranged in alignment along the drive direction (X); and a driven part (8) has a pair of opposing parts (11, 12) that are arranged so as to respectively oppose the pair of magnetic poles (9, 10) of any of the magnetic cores (MB).
