Some difference in CW and CCW motions...

Engineer on team #47, Chief Delphi, from Pontiac Central High School and Delphi Automotive Systems. In Reply to: The window motor is being mean to me... Posted by Ed on 03/29/2001 7:02 PM EST: Unlike the skepticism I have shown on the drill motors, when it comes to the window motors I know for a fact that there is a significant performance difference in the CW and CCW directions of rotations. It has to do with the relative effeciencies of the thrust bearings on the armature. So... that may be your problem. OR it could be wiring, programming or even a bad Victor. Have you tried flipping the leads of the motor and seeing if the direction of the lag changes? If it does then it is probably the Victor or some sort of coding error. For one thing, I would revert to the standard Victor Calibration (see the Victor Manual). If flipping the wires on the motor does not change direction of the slow rotation, then your motor or the mechanism that it is driving is likely the problem. I would try trading motors (RH for LH and LH for RH). If the behavior follows the motor, you have your culprit. If not, then I would look hard at the mechanism. Are you SURE you are loading the motor the same in both directions? One final thing to try (perhaps try this even earlier) is to hook up 12V directly to the motor leads in one direction and then the other. If the problem goes away, look to the Victors, the wiring or the PBASIC coding. Good luck. Joe J. P.S. Track me down in the Pits at FL if you cannot resolve this problem with the above tests. JJ |
