  • Permanent magnet rotary motor
    Patent number: 7276832
    Abstract: There is provided a permanent magnet rotary motor in which manufacture of a stator core is facilitated. The permanent magnet rotary motor includes P rotor magnetic pole sections and N slots. In this permanent magnet rotary motor, a least common multiple LCM (P, N) is set to be different from a least common multiple LCM (P/2, N), and an exciting winding is wound on each of N stator magnetic pole sections arranged in a peripheral direction so that a 120° current phase difference is obtained. N/2 divided cores 13A, 13C, 13E, 13G, 13I, and 13K of a first divided core group and N/2 divided cores 13B, 13D, 13F, 13H, 13J, and 13L of a second divided core group constitute a stator core 2.
