<p>In the rotor structure of a synchronous motor of the radial type having a shaft (12) composed of a magnetic material and in which rotor core members (20) are held by magnets (18), the magnetic shaft (12) causes leakage of fluxes during its magnetisation or the rotation of the rotor, thereby degrading the magnetising property and output performance. Therefore, the leakage of magnetic flux is decreased by decreasing the dia. of a shaft portion (12a) that faces the inner surface of the rotor body (10). The decrease in the resistance of the shaft (12) to bending is compensated for by filling the gap between the rotor body (10) and the shaft portion (12a) with a resin material (22) and by forming a knot (24). @(12pp Dwg.No.1/4)@.</p> |
