Would anyone be able to explain to me the differences, pros, and cons of needle or ball bearings as opposed to cam followers. I am looking to run a dowel pin inside a milled cam profile with the least amount of wear.
I am currently running a metal dowel pin in a milled out cam profile shaped similar a tear/water drop. The material that the profile is milled into is a sort of hard plastic but I am seeing extreme wear (abrasive) at the top of the profile where the pin has to switch direction. Does anyone have...
Does anyone know a way to measure the armature temperature of a PM DC motor without having to stop the motor? Reading the resistance between two leads requires the motor to be momentarily stopped which I have to avoid. I've been experimenting with thermocouple&thermistors and a Mercotac slip...
Looking to make a thermal conductivity measurement device. It would be nice if it could be used to measure contact resistance between two materials in addition to measuring the k value of a material.I rough schematic illustration of what I am thinking to do is attached...
Has anyone connected a thermistor to a slip ring? I initially tried using a thermocouple but since there is a change in metals going through the slip ring unwanted emf voltages were generated which were dependent upon ambient air. My next thoughts were to try a thermistor or RTD and Wheatstone...

I am looking to test fractional hp electric motors for IP66 and 67. Is it necessary to test for both dust and water? My thoughts are that if there is no water ingress there shouldn't be any dust ingress and vice versa. Therefore I was just going to test the IPX6 and X7 water specification and...
