Pulley set for a 150rpm motor (small rc car project)?
I'm building a a car for a small competition in my university (really small, like 3 teams)
The motor they are providing for the car is a small dc motor, 6v, 1.7A and 150 RPM (there's no info about the torque).
We have access to a 3D printer and wanted to print 2 pulleys to decrease the speed and gain strength (so the car can move), but I have no idea on what pulley size to use, what rpm should we aim? I know that without torque there's not much to say without testing, but any of you have at least a reference?
