Abstract

The invention discloses a motor bracket and a centrifugal fan. The motor bracket includes a main body and a recessed portion. The main body is provided with a relief hole, and the relief hole is used for passing through a power supply; the recessed portion is formed by the The main body is recessed along the axial direction of the relief hole, and the groove bottom of the recess is provided with a plurality of installation holes, and the plurality of installation holes are arranged at intervals along the circumference of the relief hole. Holes are used for fixing the motor. The technical solution of the invention can increase the self-strength of the motor support.

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...
