Can anyone point me in the right direction of designing a simple spring loaded pawl. The design I am think of allows for bi-rotational spur gear with an external pawl. The pawl is spring loaded to intersect the tooth gap, but a certain amount of torque is needed to overcome the loaded spring and...
Thanks so much for replying guys. I think I may have mis-said my actual intentions. I don't need to emulate the potentiometer. What we were thinking was to have 3 different relays coupled with a logic gate (to make sure only one relay is latched at a time). Each relay will be responsible for...
I need some help with driving a motor externally through infrared trnasmitting. The design that we have for the motor controller uses a potentiometer to control the speed AND direction of the DC motor. The problem is I need to control the resistance just as the potentiometer would from the IR...
Hey guys thanks for helping me with this, I really appreciate it.
Aolaide I have seen the formula you posted before, but it keeps on eluding me: I am confused about what units to use in the formula.
The guys over at globo-motor sent me back an e-mail, I guess my 10 watts wasnt too off. This is...
I am having trouble with calculating the required torque to rotate a disk (composed of 2 steel disks seperated by steel ball bearings) 90 degrees. There is also a 35 pound object on the disk. Also, the disk is to only move at 6 RPM. Everytime I calculate a required torque I get astonishingly...
