converting a wiper motor into a strong servo motor
thingiverse
I had an old wiper motor made by Bosch. They are very powerful, they draw 2 to 3A, do not run very fast but have really a lot of torque, much more than what I would ever need to rotate a solar tracker (even a big size one !). However these motors are DC ones without any solution to control their position. So I decided to add a cheap 12bits magnetic encoder AS5600 and transform this motor into a servo motor https://youtu.be/WHAoFCeHm70 Full details are on hackaday : https://hackaday.io/project/187675-converting-a-wiper-motor-into-a-strong-servo-motor
