Title:
STRUCTURE OF ROTARY ELECTRIC MACHINE
Document Type and Number:
Japanese Patent JPS6022450
Kind Code:
A
Abstract:
PURPOSE:To reduce the size of a rotor structure and to enhance the efficiency of the rotor by providing two parallel windings from a main terminal of a rotor winding, connecting another two windings in series with the parallel windings, coupling the ends, and connecting an AC side terminal of a power reactor to the main terminal and a DC side terminal to the connecting point. CONSTITUTION:3-phase rotor windings are connected in double star shape, arranged in a star connection by the windings 1-3, and in another start connection by the windings 4-6. The windings 2, 5 of the one phases of the three phases of the windings 1-3, 4-6 are the neutral points 11, 12 of the star connections of the other two sets are connected reversely to each other. The AC side terminal of a power reactor 10 formed of reactors is connected to main terminals 7-9 of the windings, and DC side terminals 65, 66 are connected to the neutral points 11, 12 to flow DC to the rotor windings. In this manner, the rotor windings are efficiently disposed to enhance the efficiency of the field poles, and a rotor structure having small size and high efficiency can be formed.
