A suspension noise-reduction motor comprises a motor body, a motor housing, a seal ring and buffering components, wherein the motor housing at least partially contains the motor body, the seal ring is arranged on an air inlet of the motor body in a sleeving mode, and the buffering components are installed between the motor body and the motor housing. Due to the seal ring and the multiple buffering components, the motor body is allowed to move in a three-dimensional space, the seal ring comprises an upper shock absorption piece, a lower shock absorption piece and a connecting side wall which is connected with the upper shock absorption piece and the lower shock absorption piece and clamped on the air inlet of the motor body, an S-shaped bent mechanism is arranged on the upper shock absorption piece, and a press plate matched with a protrusion is arranged on the protrusion of the S-shaped bent mechanism so that the seal ring will not be sucked into the air inlet of the motor body. The motor body is suspended in the motor housing by means of the seal ring and the buffering components, and when the motor moves in any direction by means of an elastic mechanism, the seal ring and shock pads, a motor plastic part makes soft contact with the motor housing to achieve the effect of noise reduction.
