PURPOSE:To form a flat and small reciprocating rotary operated type electromagnet by arranging leg sections of a stator having an exciting coil by opposing to the electrodes at the surface and the reverse side of a disc rotor respectively wherein N and S poles are magnetized to the electrodes at the surface and the reverse side of the rotor each other in the same direction. CONSTITUTION:N and S poles are magnetized to the surface and the reverse side of a disc rotor 1 each other in the same direction. An output shaft 5 inserted and penetrated through the center of the rotor is engaged with bearing holes 7 for free rotation. Each leg piece 3a, 3b of a stator 4 yoke 3 having an exciting coil 2 at a central part is bent. One leg piece 3b and the other leg piece 3a are arranged by opposing to one pole at the surface of the rotor 1 and the pole at the reverse side of the rotor 1 respectively. If a reciprocating rotary operated type electromagnet is formed in this way, flatness and miniaturization will be attained by thinning the disc rotor and the yoke leg pieces. |
