I'm studying gears in class, and I'd like to use Solidworks to study the gears in motion...the only thing I can't figure out is why when I spec the RPM in the dialog box, then hit "calculate" for the motion study, the rpm changes. Why can't Solidworks just spin the motor at the specified RPM and "be done with it?"
Hi Matt,
first thing I would check is wether you've edited the motor in a time that is different from 0 s.
Infact, if you make a change when the time bar is positioned at a time that is not 0 sec, SolidWorks Motion will intepret it as a change to the value of the rpm's at that time.
Check attached pic: when you see that blue bar next to the rotary motor, it means that the motor has changed its speed from time 0 sec to time 2 sec.
In this case, in order to fix the problem you should cancel the key point at the end of the blue bar, put the time bar at time 0 sec, and then edit the motor: this way the change will occur from time 0 sec and motor wom't change its speed during motion.
