る。(f) Effects of the Invention The permanent magnet synchronous motor of the present invention includes a rotor yoke and a plurality of permanent magnet pieces arranged around the outer periphery of the yoke, and the permanent magnet pieces are placed in the grooves of the rotor yoke. It is locked by a fixed locking member, and this locking member serves as a balance device for the rotor, so the fixation of the yoke and the fixation of the permanent magnet piece attached to the outer periphery of this yoke make the locking member This is done by simply press-fitting the magnet into the groove of the yoke, and there is no need to separate the process of fixing the yoke and the process of attaching the permanent magnet piece, as in the conventional case, and the number of work steps can be reduced. Further, there is no need to attach a special part as a balance weight to the rotor, and the process for attaching the balance weight can be omitted.
