Description

Variable frequency motor structure capable of reducing noise

Technical Field

The utility model relates to the technical field of motors, in particular to a variable frequency motor structure capable of reducing noise.

Background

The motor is used as an important power source and is widely applied to various industries. The variable frequency motor is a synchronous motor, and the rotating speed is related to the power frequency. In addition, a frequency converter is matched to change the power frequency alternating current of 50Hz into alternating current with variable output frequency.

In the prior art, because the length of the whole motor is longer, the space occupation ratio is large, the noise is higher, the rear end cover matched with the installation is in an arc-shaped structure, the length is longer, and when encoder-like parts are installed in the later stage, a transition plate is required to be additionally designed for installation.

Therefore, it is necessary to design a variable frequency motor structure capable of reducing noise to solve the above problems.

Disclosure of utility model

The utility model aims to provide a variable frequency motor structure capable of reducing noise so as to overcome the defects in the prior art.

In order to achieve the above purpose, the present utility model adopts the following technical scheme:

The utility model provides a variable frequency motor structure that can noise reduction, its includes motor body, installs rear end cap on the motor body, cooperation motor body installs preceding bearing, rear bearing and fan housing, its characterized in that: the rear end cover is arranged in a plane, is attached to the side face of the motor body, and is provided with a plurality of hole grooves.

Preferably, the length of the rear end cover is 29CM.

Preferably, the rear end cover is mounted in cooperation with the rear bearing.

The beneficial effects of the utility model are as follows: this technique is through designing novel rear end cap structure to reduce holistic length, with this noise that reduces the motor in the use, adopt the rear end cap of flattening face structure simultaneously, and laminating motor body sets up, further reduces length, and spare parts such as make things convenient for all kinds of encoders, encoder cover simultaneously can directly punch the installation on the rear end cap, need not redesign transition plate, has reduced the manufacturing cost of motor.

Fig. 1 is a schematic structural diagram of a variable frequency motor structure capable of reducing noise according to the present utility model;

In the figure: 1. a motor body; 2. a rear end cover; 3. a front bearing; 4. a rear bearing; 5. and a fan cover.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

In the description of the present utility model, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," "outer," and the like indicate or are based on the orientation or positional relationship shown in the drawings, merely to facilitate description of the present utility model and to simplify the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present utility model.

Referring to fig. 1, a variable frequency motor structure capable of reducing noise includes a motor body 1, a rear end cover 2 mounted on the motor body, a front bearing 3 mounted in cooperation with the motor body, a rear bearing 4, and a fan housing 5;

The rear end cover is arranged in a plane and is attached to the side face of the motor body, and a plurality of holes and grooves are formed in the rear end cover and used for being matched with various encoders, encoder covers and other parts to be directly installed, and a transition plate is not required to be installed, so that the manufacturing cost of the motor is reduced.

The rear end cover is arranged in a plane, so that the length of the rear end cover is shortened, and the noise of the motor in the use process is effectively reduced;

In the embodiment, the rear end face of the newly designed end cover adopts a leveling face design, and meanwhile, the length of the rear end cover is shortened, and the total height of the rear end cover is greatly shortened, so that the supporting distance between the front bearing and the rear bearing is shortened, and the noise of the motor in the running process is reduced; thereby shortening the length of the fan housing and the total length of the motor.

The novel rear end cover structure is designed, so that the overall length is reduced, noise of the motor in the using process is reduced, the rear end cover with the leveling surface structure is adopted, the motor body is attached, the length is further reduced, meanwhile, various parts such as an encoder and an encoder cover can be directly punched and installed on the rear end cover, a transition plate is not required to be designed, and the production cost of the motor is reduced.

The foregoing is only a preferred embodiment of the present utility model, but the scope of the present utility model is not limited thereto, and any person skilled in the art, who is within the scope of the present utility model, should make equivalent substitutions or modifications according to the technical scheme of the present utility model and the inventive concept thereof, and should be covered by the scope of the present utility model.
