Abstract

PURPOSE: To promote a construction small in size, light in weight, and an increases of generating torque, by means of constituting a magnetic pole part with a comb line pole and plate-shape permanent magnet unit.
CONSTITUTION: A constitution of pole parts 20 to 23 of a rotor 7 is made by permanent magnet units 40 to 43 and comb line poles 30 to 37 which hold those of the units 40 to 43 betwen. And each tooth of the comb line pole 30 and 33, 31 and 32, 34 and 37 and 35 and 36 is arranged to face each other, simultaneously with S-pole of the permanent magnet unit 40 and 41, 42 and 43 made facing each otherrespectively. In this way, a magnetic flux A, B and C, D going into S-pole of the permanent magnet unit 40 to 43 and a flux E, F and G, H coming out of N-pole will be in a state of repulsion with each other resulting in each flux A to H less leaked with fluxes more flowing into and out of each tooth of the comb line poles 30 to 37, with a torque generated in the rotor 7 becoming large simultaneously with a specific feature achieved of the comb line pole-type motor, thin is shape, light in weight and small in size.
