The following year, Walter Bailey, in London, developed a prototype for a weak AC motor by making a copper disc rotate using alternating current. This was followed in 1882 by the work of Sabastian ...

overvoltage inside the motor windings, and an increase in the common-mode current. Such phenomena cause premature failure of the motor and cable insulation. A typical protective measure is the use of ...

Alternating current, aka AC, is an electrical current (flow of electrons) that reverses its direction many times a second at regular intervals. It is typically used in power supplies in many ...
