PERMANENT MAGNET TYPE ROTARY ELECTRIC APPARATUS AND METHOD FOR MANUFACTURING THE SAME |
摘要 |
<P>PROBLEM TO BE SOLVED: To provide a permanent magnet type rotary electric apparatus with high performance and high productivity that allows higher torque and reduction of use of rare-earth magnet materials and does not require high-precision processing of magnets and attachment among magnets. <P>SOLUTION: The permanent magnet type rotary electric apparatus comprises a stator and a rotor disposed inside the stator. The rotor has multiple main magnets and multiple auxiliary magnets alternately and circumferentially arranged around the outer circumference of a rotor yoke. Each of the main magnets is a rare-earth magnet and each of the auxiliary magnets is a ferrite magnet, at least one of which is an injection-moldable bond magnet. <P>COPYRIGHT: (C)2013,JPO&INPIT |
