Abstract

The invention discloses a novel Roots blower. The novel Roots blower comprises a Roots blower main body, and is characterized in that the Roots blower main body is connected with a permanent magnet synchronous motor through an integrated direct connection structure; the permanent magnet synchronous motor is not provided with a bearing; an inlet silencer is arranged at the upper end of the Roots blower main body; a safety valve connected through a check valve is arranged on the side edge of the Roots blower main body; an outlet silencer is arranged on the safety valve; and the outlet silencer is provided with a shockproof joint. A permanent magnet motor rotor is directly connected with a rotor of the Roots blower main body in a shaft extension mode, a flange of the Roots blower main body can be used as a front cover of the motor, a back cover can be directly simplified into a thin iron plate, a front bearing, a rear bearing, a front end cover and a rear end cover are omitted simultaneously, the cost is reduced, and the structure is simplified.
