摘要： PROBLEM TO BE SOLVED: To provide a motor rotor which brings a distribution waveform of magnetic pole magnetomotive forces closer to a sine wave without causing a dragging loss or a windage loss. SOLUTION: Each of a plurality of core plates 32 making up the rotor core 31 of a rotor 30 has: a plurality of magnet holding portions 33 each formed to hold a permanent magnet 50; and a plurality of caulking portions 35 for temporary fixing overlapping core plates 32 together.

Hence the distribution waveform of magnetic pole magnetomotive forces is brought closer to a sine wave. COPYRIGHT: (C)2011,JPO&INPIT
