Stable low-noise permanent magnet motor

Abstract

The invention relates to the technical field of motors, in particular to a stable low-noise permanent magnet motor which comprises a motor body installed in an installation box. Communication holes are formed in side plates, in the length direction of the motor body, of the installation box, a plurality of cooling fins are arranged on the side face of the motor body, and the space between every two adjacent cooling fins is filled with a sound absorption part. The plurality of cooling fins are matched with a fan assembly mounted on a rotating shaft of the motor body to cool the motor body; a fixing assembly is arranged in the installation box and used for fixing the motor body, the fixing assembly comprises a fixing piece and a clamping piece elastically connected with the fixing piece, the fixing piece and the clamping piece are both installed on the damping platform, the motor body is installed on the damping platform in a sliding mode through the installation piece, and the clamping piece is used for clamping the installation piece. The motor body is clamped and fixed through the fixing assembly, and the problem that the damping and noise reduction functions of the permanent magnet motor cannot be continuously completed after a rubber pad arranged at the installation position of the permanent magnet motor is aged at present is solved.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a stable low-noise permanent magnet motor. Background technique [0002] Permanent magnet motors provide excitation with permanent magnets, which have the advantages of simple structure and low processing and assembly costs. Excitation losses, improving the efficiency and power density of the motor. [0003] At present, when the permanent magnet motor is in use, shock-absorbing rubber pads are added to its connection position to reduce vibration and noise. However, since the rubber pads tend to lose elasticity after long-term use, the ability to reduce vibration and noise cannot be achieved. Contents of the invention [0004] The purpose of the present invention is to provide a stable low-noise permanent magnet motor to solve the problem that the shock and noise reduction function of the permanent magnet motor cannot continue to be completed after the rubber pad installed at th...
