The Brush DC Motor - an Overview
This discussion describes the brush DC motor, and how it differs from a brushless DC motor, a stepper motor, and other motor types. In this discussion, we'll break down the brush DC motor, showing exactly how it operates. We will review manufacturer motor specifications, speed/torque curves, motor sizing, and power ratings. We will discuss motor commutation using brushes.

Brush DC Motors - Making Them Stop
This discussion moves our focus from energy input to braking, friction, torque control, and back EMF effects. During this discussion we will discuss what happens as we decelerate. We will discuss regenerative braking.
