Title: Reluctance motor
Inventor: MAKITA SHINJI
IPC: H02K19/10
Filed: 2000-09-19
Abstract: PROBLEM TO BE SOLVED: To solve the problem of a conventional technique for reducing torque ripples, by skewing the magnetic center angle of a stator or rotor in the direction of rotation by an angle equivalent to one slot angle of the stator, the difference in magnetic reluctance in rotational positions is reduced, and this causes reduction in the output torque. SOLUTION: Four barrier patterns are formed on a rotor laminated sheet 4, and the rotor is formed by alternately laminating two types of rotor laminated sheet 4, different in barrier pattern specification (barrier specification A, barrier specification B). When the rotor is seen from the circumferential direction, the barriers 5a are formed so that the intervals between the circumferential ends of the barriers are all equal. With this arrangement, the waveform of torque produced by the rotor laminated sheet 4 to the barrier specification A is opposite in phase to that of the waveform of torque produced by the rotor laminated sheet 4 to the barrier specification B. As a result, the respective torque fluctuations are canceled out by each other and thus torque ripples are reduced.  Unlike the conventional techniques (techniques of skewing), this constitution is free of the problem of reduced magnetic reluctance difference at rotational positions and does will cause reduction in the output torque.
