Abstract

PURPOSE:To reduce the thickness of an entire motor by forming a rotor of a disc-shaped magnet. CONSTITUTION:A rotor 5 of disc shape secured to a rotational shaft 4 is composed of a magnet holding plate 6 made of synthetic resin material and a ferrite magnet 7 of hollow disc shape engaged with the periphery of the plate 6. The magnet 7 has N-poles and S-poles alternately with equal width in the circumferential direction of the poles 8 of the rotor magnetized through thickness direction of the plate. First and second stators 9, 10 disposed at both sides of the rotor 5 are respectively composed of a stator plate 12 having a plurality of stator poles 11 arranged at an equal interal in a ring shape, a stator plate 14 having a plurality of stator poles 13 arranged at an equal interval in a ring shape, and first and second coils 15, 21 for exciting the poles 11, 13 in different polarities.
