ABSTRACT:
An electromagnetic actuator with a smaller size and an increased strength is provided. In the electromagnetic actuator, a first arm portion and a second arm portion that connect the magnetic poles of a stator extend to the outside of a rotor housing. A first coil and a second coil are wound around the extending portions. In other words, the first coil and the second coil are exposed to the outside of the rotor housing. Accordingly, compared with a case where the rotor housing also houses the first coil and the second coil, the width of the electromagnetic actuator can be reduced by the thickness of the rotor housing. Thus, the electromagnetic actuator can be made compact.
