For the past couple of months, I’ve been meeting with colleagues with the goal of designing and 3D printing electric motors in my classes. This is a collaboration between Sonoma State professor Daniel R. Soto, Lawrence Livermore Lab test engineer Jacob Aman, and Roblox software engineer Alex Katz. Jacob designed a working model using FEMM (Finite Element Method Magnetics), and Apple Blossom School is letting us use the 3D printer in their makerspace.
Eventually, the goal is to have students build stuff with the motors they design, such as a device for a solar oven to track the sun.
