Definitions:

Shunt Motor

A motor that contains only a shunt field winding.

Square Wave Voltage

An electrical signal that switches instantaneously between two levels, used for digital communication, characterized by its distinct, non-variable high and low states.

DC Average

The average value of a direct current (DC) over a period of time, often used to describe power or signal levels.

Positive Pulses

Electrical signals that transition from a lower to a higher voltage level, typically representing a binary '1' in digital circuits.
