AFCIs work by sensing when an arc fault is about to occur and then interrupting the flow of electricity before the arc can form. Read more..
What is a synchronous motor?
Unlike an asynchronous AC motor, a synchronous AC motor rotates at the same speed as the frequency of the AC power supply. In order to achieve this, the synchronous AC motor must be synchronized with the power supply using a feedback system. Read more..
