Title:
回転電機
Document Type and Number:
Japanese Patent JP7141250
Kind Code:
B2
Abstract:
A brushless winding field type rotary electric machine 10 positioned between a starting device 4 and a stationary case 5, comprising a stator 3 held in the stationary case 5 and internally equipped with an AC coil 14 for generating a rotating magnetic field by an AC current; a field core 6 held in the stationary case 5 and internally equipped with a field coil 2 excited by a DC current; a rotor 1 disposed around the outer periphery of the starting device 4 and held so as to be rotatable with respect to the stator 3 and the field coil 2; a first air gap 11 formed between the stator 3 and the rotor 1, thereby delivering a magnetic flux between the two; a second air gap 12 formed between the field core 6 and the rotor 1, thereby delivering a magnetic flux between the two, wherein the second air gap 12 has an inclined section inclined with respect to the axial direction of a rotation shaft 7 so that the radially outer portion 210 of the rotor 1 is positioned on the radially outer side than the field core 6.
