AC Motors
... AC motors are used worldwide in many residential, commercial, industrial, and utility applications. Motors transform electrical energy into mechanical energy. An AC motor may be part of a pump or fan, or connected to some other form of mechanical equipment such as a winder, conveyor, or mixer. AC mo ...

... Induced current is always in a direction to oppose the change that causes it. This is a statement of the conservation of energy because to induce a current energy has to be put into the circuit. The source has to do work to drive the current through the coil. It is this “work done” that appears as ...
