If you’re building something that moves, chances are you’ll be using an electric motor. There are tens of thousands of different motors out there, each with their own properties, speeds, torque, and sizes. How do you pick the right motor? Most of the time it’s a highly educated guess, but [Solenoid] has a better idea: just 3D print a motor designed by a calculator that will give you the properties you need
This entry for The Hackaday Prize is just a web-based calculator for motor designs that takes torque, speed, size, or form factor as an input and spits out a complete motor design. Sure, you’ll need to wind coils on a 3D printed frame, but this calculator removes the need to calculate inductance, coil capacitance, and all the other bits needed to construct an efficient motor.
While actual products made in the millions will still be using off the shelf motors, this project is perfect for one-offs. If you want to motorize a telescope mount, this project will design a motor given the power and resolution per steps required. If you want to build a wind turbine, this calculator will put blades right on the outrunner of a brushless motor. It’s a great project, and something we can’t wait to see the results of.
