Full-Rectification

The conversion of AC (alternating current) to DC (direct current) using both halves of the input waveform, usually in power supply or electronic signal processing.

Rotor

The rotating part of an electrical or mechanical device, such as the part in an electric generator or motor which turns around a stationary part called a stator.
