I believe the RB-NEX-40s are defectively designed. When you give them a signal, they run at the given speed for a few seconds, and then they suddenly slow way down. They will not continue to run at the given speed continuously. I went through countless emails with manufacturer customer support and could not resolve the issue. All four motors I ordered exhibited the same behavior even after calibration. I was authorized to return all the motors to Robotshop and received a refund. I ordered an alternative motor, three of the Feetech FS5106R motors. I connected the Feetech motors to my project without any other changes and everything worked normally immediately. I find it hard to believe that I randomly received four defective motors and feel that the RB-NEX-40 is likely just flawed. As a result, I do not recommend that anyone buy the RB-NEX-40. I am extremely happy with the Feetech FS5106R motors if anyone is looking for an alternative to the RB-NEX-40. FYI I am not a noob, but an experienced engineer.
Works as described. Great torque, metal gears, great performance.
Fonctionne comme décrit. Excellent couple, engrenages en métal, excellentes performances.
