Title:
DYNAMO-ELECTRIC MACHINE
Document Type and Number:
Japanese Patent JP2001069694
Kind Code:
A
Abstract:
To fully reduce the leakage of magnetic flux at the ends of a rotor or stator.
With respect to a rotor 2, an iron core 12 is installed on the circumference of a frame body 11, permanent magnets 13a and 13c for field system are embedded in the iron core 12, and permanent magnets 14 for reducing respective leakage flux are installed at both the ends of the permanent magnets 13a and 13c for field system. A rotary shaft 3 passes through the center of the frame body 11 and is secured on the frame body 11. With respect to a stator 4, a plurality of coils 16 for field system are placed circumferentially inside the cylindrical iron core 15.
