Abstract

PURPOSE: To reduce an armature reaction reactance, by making the magnetization side section of permanent magnets thinner, and by making the demagnetization side section thicker.
CONSTITUTION: To the central shaft of the magnet of a pole N, the magnet 2b of the left half is made thicker, and the magnet 2a of the right half is made thinner. In the same manner, on the magnet of a pole S, a magnet 3a is made thinner, and a magnet 3b is made thicker. Generally on the magnet of a large capacity, in many cases, the magnet is divided in the rotor shaft direction and in the circumferential direction, and also in this case, for the magnets 2b, 3b on the demagnetization side, thicker magnet pieces are used, and for the magnets 2a, 3a on the magnetization side, thinner magnet pieces are used to be fitted with adhesives. Besides, in order to permit the magnet outer-diameters to coincide with each other, inside the thinner magnets 2a, 3a, the spacers 6 of magnetic units are used. As a result, even on the demagnetization side, because of the thicker magnets 2b, 3b, an armature reaction reactance is reduced.
