PERMANENT MAGNET TYPE ROTARY ELECTRIC MACHINE |
| 摘要 |
<p><P>PROBLEM TO BE SOLVED: To minimize a so-called torque ripple with minimum reduction of an average torque. <P>SOLUTION: An embedded permanent magnet type rotary electric machine includes a plurality of rotor sections. Each section has a plurality of laminated boards 38. Permanent magnets are asymmetrically arranged inside openings 42 formed in the laminated board to reduce torque vibration caused by a harmonic component of magnetic flux. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
