Claims
- 1. A rotary electric machine comprising:a stator; and a rotor being divided into a plurality of rotor core units along the circumferential direction of said rotor opposite a gap between said stator and said rotor, each rotor core unit having a plurality of permanent magnets arranged along said circumferential direction of said rotor, projecting magnetic core portion between said permanent magnets and rotor core yoke portions, each of said rotor core yoke portions forming a magnetic path for conducting magnetic flux from said permanent magnet.
- 2. A rotary electric machine as defined in claim 1, wherein said rotor is divided into the plurality of said rotor core units in the circumferential direction at a middle position of said projecting magnetic core portion.
- 3. A rotary electric machine as defined in claim 1, wherein said rotor core is divided into the plurality of said rotor core units at a middle position of a circumferential width of said permanent magnet.
- 4. A rotary electric machine as defined in claim 1, wherein said rotary electric machine is an outer rotor electric machine.
- 5. A rotary electric machine, wherein said rotary electric machine as defined in claim 1 is used in an electric vehicle.
