ABSTRACT:
An electromagnetic device includes a magnet rotor having a rotary shaft and a stator having an excitation coil configured to apply a rotation force to the rotor. The magnet rotor includes a hollow cylindrical permanent magnet, a rotary shaft disposed in a hollow space portion of the permanent magnet, and a driving arm that rotates around the rotary shaft integrally with the permanent magnet. The magnet and driving arm are reliably secured, not easily separated during use, and includes a structure that facilitates machining and assemble.
