Title:
COIL FIELD TYPE ROTOR FOR ELECTRIC ROTARY MACHINE
Document Type and Number:
Japanese Patent JPH0974698
Kind Code:
A
Abstract:
To prevent the deflection of a rotor coil as a heating element due to a centrifugal force during its rotation and also to make it possible to cool the rotor coil.
By paying attention to the shape and fixing method for a holder 13, a cross section of the holder 13 is made to a shape of isosceles triangle and is coupled directly to a second core 9a with holder bolts 14 or the like, and thus the deflection of a rotor coil 8 by a centrifugal force can be prevented during the rotation of the rotor coil 8. Also, the holder 13 is made of a metal, its heat dissipation can be improved, and also the rotor coil 8 can be cooled.
