Rotor for a rotating electric machine

A rotor of a rotating electric machine comprising:

• a shaft;
• pole cores with a plurality of claw-like magnetic poles formed on an outer periphery thereof being assembled so that said claw-like magnetic poles engage with each other and rotate integrally with said shaft;
• a plurality of permanent magnets each of which is disposed between two adjacent ones of said plurality of claw-like magnetic poles and each of which is magnetized in a direction that diminishes magnetic flux leakage between said adjacent ones of said plurality of claw-like magnetic poles;
• and
• a resin-made magnet holding member fit between side faces of said plurality of claw-like magnetic poles to hold said plurality of permanent magnets, said resin-made magnet holding member being formed in a ring shape having a plurality of interconnected segments joined by V-shaped turns.

A rotor for a rotating electric machine, comprising:

• a shaft;
• a plurality of magnets;
• pole cores having a plurality of claw-like magnetic poles disposed so that adjacent ones or said plurality of claw-like magnetic poles are separated by ones of said plurality of magnets;
• and
• means for containing said plurality of magnets, said plurality of magnets being held firmly by said means for containing so as to prevent a generation of high frequency impact magnetic noise, said means for containing connecting circumferentially axial ends of adjacent two of said plurality of magnets at each axial end of said claw-like magnetic poles.

• a holding member formed of a resin material and having an outermost surface radially inward of said plurality of claw-like magnetic poles;
• a plurality of connecting portions;
• and
• a plurality of board portions connecting said connecting portions;
• wherein said plurality of permanent magnets are disposed on said plurality of board portions, and said plurality of permanent magnets have end faces disposed at said plurality of connecting portions.

A rotor for a rotating electric machine comprising:

• a shaft;
• a plurality of permanent magnets;
• pole cores having a plurality of claw-like magnetic poles disposed so that adjacent ones of said plurality of claw-like magnetic poles are supply ones of said plurality of permanent magnets;
• and
• means for containing said plurality of permanent magnets, said plurality of permanent magnets being held firmly by said means for containing so as to prevent a generation of high frequency impact magnetic noise, said means for containing including means for covering and retaining an end portion of each of said plurality of permanent magnets at axial ends of each of said plurality of claw-like magnetic poles, said means for containing including a holding member formed of a resin material and having an outermost surface radially inward of said plurality of claw-like magnetic poles, said holding member completely covering said plurality of permanent magnets.

A rotor and a stator for use in an alternating current generator, said rotor comprising:

• a rotatable shaft;
• pole cores having a plurality of claw-like magnetic poles, said plurality of claw-like magnetic poles being rotatable with said rotatable shaft;
• a plurality of permanent magnets, one of said plurality of magnets being disposed between adjacent ones of said plurality of claw-like magnetic poles;
• and
• means for holding said plurality of permanent magnets in a position between said plurality of claw-like magnetic poles, said means for holding being formed of a resin material and comprising:
• a plurality of connecting portions which hold end faces of said plurality of magnets;
• and
• a plurality of interconnecting members that interconnect said plurality of connecting portions circumferentially covering axial ends of said plurality of claw-like magnetic poles, a number of said plurality of interconnecting members equalling a number of said plurality of magnets;
• and
• said stator comprising:
• a stator core;
• and
• a plurality of stator coils;
• said stator being separated from said plurality of claw-like magnetic poles by an airspace having a predetermined size which does not change during rotation of said rotor.
