Description

Technical Field

[0002] Permanent magnet synchronous servo motor is a kind of AC permanent magnet servo motor. It is widely used in the field of small and medium capacity high-precision transmission. It generates a magnetic field by adding permanent magnets to the rotor. Due to the inherent characteristics of permanent magnet materials, it no longer requires external energy to establish a strong permanent magnetic field in the space around it, which can simplify the motor structure and save energy. Permanent magnet synchronous servo motor has some advantages, including high power factor, high efficiency, simple structure, reliable operation, small size, light weight and low loss.

[0003] Some traditional permanent magnet synchronous servo motors on the current market still have some defects when in use. For example, most servo motors are fixed by bolts, which makes the installation process cumbersome, inconvenient to disassemble and easy to slip. In addition, the servo motor will generate a lot of heat during operation. If the heat is not dissipated in time, the service life of the permanent magnet motor will be reduced, thereby easily reducing the practicality of the permanent magnet motor. For this reason, we propose a permanent magnet synchronous servo motor. Utility Model Content
