Using an asynchronous exchange avoids the risk of losing the connection (because of server maintenance and so on) and, thus, the response.
使用异步交换能够避免失去连接(因为服务器维护等等)以及因此而失去响应的风险。
Asynchronous generator has advantages of simple and stable structure, small and light, few of auxiliaries and convenient maintenance, etc.
异步发电机具有结构简单、牢固、体积小、重量轻、辅助设备少、运行维护方便等优点。
Meanwhile, the structure of toroidal windings asynchronous motor has better thermal diffusivity and lower maintenance costs than the structure of squirrel-cage asynchronous motor.
同时，环形绕组异步电机的结构较笼型异步电机的结构具有更好的散热性及较低的维修成本。
