A motor and its motor junction box

Abstract

The invention discloses a motor and a motor junction box thereof. The motor junction box comprises a cylindrical junction box body, a shielding partition plate arranged in the junction box body and afront cover plate and a rear cover plate which are respectively located at the front opening and the rear opening of the junction box body. The shielding partition plate is located at the eccentric position of the junction box body so that a large chamber and a small chamber are formed inside the junction box body. A frequency conversion controller can be placed in the large chamber, and a signaltransceiver can be placed in the small chamber. According to the motor junction box, more space, materials and cost can be saved through the arrangement of the junction box body with the cylindrical structure and the motor junction box is further matched with the shape of the motor. In addition, the arrangement of the multi-cavity structure is utilized and the shielding partition plate is utilizedto solve the problem of signal interference and improve the information transmission accuracy of the junction box.

Description

technical field [0001] The present application relates to the field of permanent magnet synchronous motor equipment, in particular to a motor junction box. In addition, the present application also relates to a motor including the above-mentioned motor junction box. Background technique [0002] With the development of permanent magnet synchronous motor technology and the application of automatic control, coupled with the trend of miniaturization and intelligence of motor structure, the integrated design of motor and frequency conversion controller has begun to be realized. [0003] In the integrated structure of the permanent magnet synchronous motor and the frequency conversion controller used in the central air-conditioning water pump, in the junction box of the ordinary motor, the connection socket is used to connect the external power supply, and when realizing the integrated design of the frequency conversion controller and the motor, the three parts of the motor The ...

AI Technical Summary

Problems solved by technology

[0005] 1) Ordinary junction boxes are difficult to meet the installation of frequency conversion controllers and internal wiring problems;

[0006] 2) For frequency conversion controllers for wireless signals, it is difficult for ordinary junction boxes to shield signals;

[0007] 3) If the controller is installed separately, it will take up a lot of space and poor sealing;

[0008] 4) The shape of the ordinary junction box does not match the cylindrical structure of the motor, which is not beautiful
