Permanent magnet synchronous motor

Abstract

The invention discloses a permanent magnet synchronous motor, which comprises a permanent magnet synchronous motor body, a first shell and a second shell, wherein a through groove is formed in one side of the top of the first shell, the first shell is installed on the upper portion of the permanent magnet synchronous motor body, the second shell is installed on the lower portion of the permanent magnet synchronous motor body, first fixing plates are fixedly connected to the two sides of the first shell correspondingly, second fixing plates are fixedly connected to the two sides of the second shell correspondingly, the bottoms of the first fixing plates are fixedly connected with the tops of the second fixing plates, first sound absorption cotton is arranged on the inner surface of the first shell, second sound absorption cotton is arranged on the inner surface of the second shell, and a first limiting plate is fixedly mounted on one side of the top of the permanent magnet synchronous motor body. According to the invention, the silencing structure is additionally arranged on the permanent magnet synchronous motor structure, so that the noise of the permanent magnet synchronous motor in the use process is reduced, the working environment is improved, and the work of workers is facilitated.

Description

technical field [0001] The invention belongs to the technical field of motors, and in particular relates to a permanent magnet synchronous motor. Background technique [0002] The permanent magnet synchronous motor provides excitation with permanent magnets, which makes the structure of the motor relatively simple, reduces the cost of processing and assembly, and saves the collector ring and brush that are prone to problems, which improves the reliability of the motor operation; and because no excitation is required current, without field losses, increasing the efficiency and power density of the motor. Permanent magnet synchronous motor is composed of stator, rotor and end cover and other components. The stator is basically the same as the ordinary induction motor, and adopts a lamination structure to reduce the iron loss when the motor is running. The rotor can be made solid or stacked with laminations. The armature winding can be concentrated full-pitch winding, or dis...
