The asynchronous callback equivalent of the synchronous operation shown in Example 4 consists of a request operation like this.
在例4中显示的同步操作的等价异步回调包含如下一个请求操作。
After started, induction motor is changed into synchronous operation not only to improve its power factor, but also to supply reactive power for power supply and improve system power factor.
异步电动机同步化指绕线式异步电动机起动后，变成同步运行后不仅可以提高该机的自身的功率因数，还可以向电网提供一定的无功功率，提高整个系统的功率因数。
