The invention relates to a motor slip ring room structure and particularly relates to a doubly-fed wind generator slip ring room structure, so as to solve the problems of unsatisfactory temperature reduction and carbon powder emission effects in the prior scheme of the doubly-fed wind generator slip ring room. The slip ring room structure comprises a slip ring room main body, a first insulated airguide plate, a second insulated air guide plate, a third insulated air guide plate, a fourth insulated air guide plate, a spiral case protection cover with a powder emission port at the bottom part and a centrifugal fan, wherein the side plate of the slip ring room main body is provided with an air inlet; the first insulated air guide plate is arranged on the bottom plate of the slip ring room main body; the second insulated air guide plate is arranged between a connection flange plate at one end of the slip ring room main body and the spiral case protection cover; the third insulated air guide plate is arranged on the side plate of the slip ring room main body above the air inlet; the fourth insulated air guide plate is arranged on the top plate of the slip ring room main body; the periphery of the spiral case protection cover is fixed on the connection flange plate at one end of the slip ring room main body; and the centrifugal fan is located in the spiral case protection cover andfixed on a slip ring or a rotating shaft.
