惯性状态改变的具体表现

电机启动过程及停止过程都是一种惯性改变的过程，改变惯性的过程，即运行对象受力改变的过程，改变的时间越短、受力越大，状态改变即越明显，直接的物理表象为人的直觉可以感受到的振动，对于电机产品而言，可能是声音和位移的变化。

为此，电机安装使用过程中的固定非常必要，例如通过电机底脚面、端盖法兰面与安装基准进行固定，必要时增加其他限位措施。在电机运行过程中，会因为难以规避的振动问题发生固定的松动问题，因而定期的保养和维护特别必要。

The specific manifestation of inertia state change
The process of starting and stopping a motor is a process of inertia change, which refers to the process of changing the force on the operating object. The shorter the time of change and the greater the force, the more obvious the state change. The direct physical appearance is the vibration that can be felt by human intuition. For motor products, it may be the change in sound and displacement.
Therefore, it is necessary to fix the motor during installation and use, such as by fixing the motor foot surface, end cover flange surface with the installation reference, and adding other limiting measures if necessary. During the operation of the motor, fixed looseness may occur due to unavoidable vibration issues, so regular maintenance and upkeep are particularly necessary.
