Document Summary

Lab # 3 open-loop control of a dc motor. To understand and gain insight about how a dc motor works and how to create circuits in order to make a dc motor spin. Engineers use electric motors for a variety of applications requiring movement (robots, automation equipment, disk drives, etc. ). A motor is only useful if we can control it. Sometimes we want to control the motor"s position (robot arms, 3d printer), sometimes its speed (cruise control), and sometimes its torque (human-interface robots, heavy machinery). In this lab, we will investigate controlling the voltage across a motor, which will control the speed of the motor. The steady-state speed of the motor is proportional to the voltage across its terminals, unless acted upon by an outside force. In this lab we will be using simple circuits to make a dc motor spin. Part i: running a dc motor with a simple circuit.
