What Are The Components That Affect The Life Of A Single-phase Asynchronous Motor?

Bearings are one of the very important and key components in single-phase asynchronous motor products. In order to ensure the quality and performance compliance of motor products, the design stage is very important for the bearing selection of single-phase asynchronous motors, including bearing load and the actual use of the motor. Condition matching, single-phase asynchronous motor installation method and bearing matching, motor speed requirements for bearing performance, and motor vibration and noise control requirements for bearing performance.

In addition to this, the assembly process is a very critical factor. There are two types of single-phase asynchronous motor installations: cold-pressing assembly and hot-fitting assembly. During the cold-pressing process, it is necessary to ensure that the end face of the mating ring is stressed during the pressing-fitting process, and the cage cannot be subjected to external force during the pressing-fitting process. The method of installing the bearing on the shaft after heating; the commonly used heating methods include oil heating, oven heating and induction heating. Compared with the oil heating method, the temperature control is better, while the other two heating methods have heating temperature. If the possibility is too high, it will cause the bearing performance to fail, and the noise problem will occur in a short time after the motor is running.

In the actual assembly process, the single-phase asynchronous motor is not suitable, the initial placement is not concentric, the frame is stressed, and the temperature is too high during the shrink-fit process, which are all possible problems. To solve the quality problem of the bearing system, the process assembly control is particularly critical. .
