Abstract
A rotary solenoid () includes a stator (), a rotor (), and a torsion spring () connected between the stator () and the rotor (). The stator () includes an armature () having three stator poles () cooperatively defining a substantially cylindrical space () and a coil () wound about one of the stator poles (). The rotor () includes a shaft () rotatably assembled to the stator () and a rotor core () fixed to the shaft () and received in the cylindrical space (). The rotor core () has three rotor poles () corresponding to the stator poles (). The rotor () stays at a first position under the force of the torsion spring () and rotates to a second position under the force of the torsion spring () and the magnetic force of stator () when the coil () is powered.
