Abstract

PURPOSE:To simplify winding work and to obtain such a motor that can reduce the cogging torque by blocking up an opening of a slot with ferromagnetic substance member holding a non-magnetic substance member. CONSTITUTION:An opening of a slot 1(a) has almost the same width as that of a bottom part so as to make it as wide as possible. A space of the slot 1(a) is partitioned off by the straight-like projected poles 1(b) which are arranged at every equal angle interval. A winding 3 is wound on the projected poles 1(b) in series, or it is inserted into the slot 1(a). After having wound the winding 3, the opening of the slot 1(a) is blocked up with a magnetic wedge 4 that two ferromagnetic substances 4(b) conformed to the opening of the slot 1(a) holding a non-magnetic substance between them are formed together as a unit. In this case, the locating stoppers 1(c) of the magnetic wedge 4 is provided to the end part of the projected poles 1(b) so that the ferromagnetic substance members 4(b) can be obtained a specific gap width with a rotor 2. Two ferromagnetic substance members 4(b) are cut off magnetically by a linear projection of the projected non-magnetic substance member 4(a).
