Abstract
The present disclosure provides an electromagnetic actuator that drives an armature by an electromagnetic force. The electromagnetic actuator includes a stator, a coil, and an insulator. The stator is formed of a magnetic material and has a cylindrical portion. The coil is disposed outside of the stator. The coil generates a magnetic field when being energized. The insulator is disposed in a particular region of the stator facing the coil in a radial direction. The insulator extends partially along the stator in a circumferential direction and suppresses a current flowing through the stator in the circumferential direction. The stator is continuously formed entirely along the circumferential direction by the magnetic material.

An electromagnetic actuator that drives an armature by an electromagnetic force, the electromagnetic actuator comprising:
- a stator that is formed of a magnetic material and has a cylindrical portion;
- a coil that is disposed outside of the stator, the coil generating a magnetic field when being energized;
- and
- an insulator that extends partially along the stator in a circumferential direction and suppresses a current flowing through the stator in the circumferential direction, wherein
- the stator includes a portion that is continuously formed entirely along the circumferential direction by the magnetic material,
- the cylindrical portion of the stator is provided with the insulator, and
- the insulator is formed of a slit extending along an axial direction of the cylindrical portion and located in a region of the stator where the stator faces the coil in a radial direction of the cylindrical portion.
