Definitions:

Series

A connection of electrical components in a circuit end-to-end such that there is only one path for current flow, leading to the same current through all components.

Two-phase Power System

A two-phase power system is an electrical power distribution method that uses two alternating currents, which are offset in phase by one-quarter of a cycle (90 degrees).

Phase

A measure of the position of a point in time on a waveform cycle, often used in the context of alternating currents to describe the difference in timing between two waveforms.

Consequent-pole Motor

A type of electric motor design that uses additional poles (generated by connections in the winding) to improve torque and reduce pulsations in multi-phase systems.
