Claim 6:
7. The reluctance motor of claim 1, characterized in that the motor comprises
an N-pole stator magnetic pole and an S-pole stator magnetic pole which are arranged parallel with in the circumferential direction; and
a permanent magnet PM1 arranged between a portion close to a distal portion of a tooth the N-pole stator magnetic pole and a portion close to a distal portion of a tooth of the S-pole stator magnetic pole,
wherein a relationship of Lts is equal to or less than “0.9×Ltf”, wherein Ltf is a maximum value of a circumferential width between the portions close to the teeth of the N-pole and S-pole stator magnetic poles and Lts is a circumferential width of a tooth of a middle portion located between a tooth end of the stator and a back yoke thereof.
