I always try really hard to calculate the torque needed to lift an arm in order to use efficient gear ratios in order to run motors at roughly 50% stall torque as to keep the motor “comfortable” and prolong it’s lifespan. I ALWAYS use clutches to protect the motor. Lately some kids in my robotics club have had the PWM ends snap on them. Because the bots they were making were not made for competition i just cut of the end of the motor wire and one end of an extension cable and soldered the wires together. The ends often get in the way when building robots and i have had a few close calls myself with the PWM ends. I know a lot of PWM stuff that you can get use shielded male PWM ends. I was thinking about how useful a little plastic piece that covered the PWM ends would be to protect the fragile ends while building a bot. What do you think? would you buy a pack?
