nema 17 stepper motor is used in a 3D printed wind turbine. Michael Curry, Kansas City’s master of 3D printing, built and printed a wind turbine in 3-D to take advantage of Missouri’s endless wind power, which may be exactly what we need to deal with complaints from other important people.
The alternator he built uses nine rings of 22 gauge copper wire wound around a 3-D printed magnetic core and stored in a supporting disk. Each coil is, of course, connected in three creative stages of an alternating set. In theory, when the wind rotates the turbine blade, the magnet rotates above the coil. Alternating magnets excite electrons through alternating positive and negative magnetic fields on coils.
The movement of electrons is rectified by two bridge rectifiers into a DC power supply, “he said. Although it looks good and should be done well in theory, the results are quite different. Although the wind is very strong, the alternator can only produce 196.9 microvolts. “Yes, my alternator doesn’t work very well,” he concluded.
That’s why it’s always good to have an alternative at hand. When you’ve built some 3D printers, you can easily find one in the nema 17 stepper motor.
“I heard that stepper motors can make great small generators,” Curie said. We did a quick experiment. An Adafruit nema 17 stepper motor, 2 bridge rectifier, multimeter, capacitor, bulb, and electric drill. The principle is that we rotate nema 17 stepper motor with an electric drill, which generates alternating voltage in two coils.
