Abstract

The invention discloses a motor support and a centrifugal fan. The motor support comprises a main body part and a recessed part, a receding hole is formed in the main body part and used for allowing amotor to penetrate through, the recessed part is formed in the mode that the main body part is concave in the axial direction of the receding hole, a plurality of mounting holes are formed in the groove bottom of the recessed part, the mounting holes are formed at intervals in the circumferential direction of the receding hole, and the mounting holes are used for fixing the motor. According to the technical scheme, the self strength of the motor support can be improved.

Description

technical field [0001] The invention relates to the field of fans, in particular to a motor support and a centrifugal fan. Background technique [0002] The motor fixing hole in the traditional motor bracket is opened directly on the main plane of the motor bracket, and the motor is fastened by screws. This kind of opening method has higher requirements on the material strength and thickness of the volute back plate. In practical applications, when the motor is fastened by screws, the back plate of the volute is easily stretched and deformed, which makes the flatness of the motor support worse and affects the concentricity of the impeller, the front plate of the volute, the air inlet ring and the motor support. degree, thereby changing the axial and radial clearances between the impeller and the air inlet ring, which is detrimental to the performance of the fan. Contents of the invention [0003] The main purpose of the present invention is to propose a motor bracket aim...
