Posted by on in DC Motor Controllers

When most of us get to grips with applying power to a DC motor, to watch it spin round, usually our next task is to determine how fast it is spinning that is, determine it's speed of rotation. There are many different ways of measuring a DC motor's speed including using an optical encoder. Before using a FPGA to automate the task we firstly measured the DC motor's speed of rotation by connecting the digital and analog outputs of a photo-sensor board to an oscilloscope. What we discovered during this first phase of measurements is the subject of this blog post.
