Eeny, Meeny, Miny, Motor: Creating and Controlling Motion
This chapter covers the different kinds of motors and how to choose between them. Once you know what power and torque are and how to estimate what you need for a certain project, it becomes less voodoo and more of a process of elimination. We’ll also talk about some other ways to create motion, from solenoids and linear motors to emerging technologies like muscle wire. You can download the full chapter from this link.
