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.
