电子计算机所使用的外部设备中,有不少设备用交流电机做为动力,例如GSJ—1F快启停光电输入机、CYD—103快速打印机、某些穿孔机等等。大家知道,计算机使用外部设备时,有时候是很频繁的,而有时候则在较长时间内都不会使用它。对于那些使用不频繁,停止工作的时间又长的外部设备,在不用的时间内最好让电机处于停转状
Among the external devices used in electronic computers are a number of devices powered by AC motors such as the GSJ-1F fast start-stop optical input unit, the CYD-103 fast printer, some punches and the like. We all know that computers use external devices, sometimes very often, but sometimes it will not be used for a long time. For those who use less frequently, stop working for a long time outside the device, in the unused time it is best to let the motor in a stall
