I am wrong.
Posted by Joe Johnson at 2/8/2001 2:39 PM EST
Engineer on team #47, Chief Delphi, from Pontiac Central High School and Delphi Automotive Systems. In Reply to: Re: Might be sleeping... Posted by Mike Gray on 2/8/2001 8:02 AM EST: I just got a frantic message from my Johnson Electric contact. It seems that he was wrong yesterday when he told me the motor was not biased. When he confirmed with his manufacturing sources in Hong Kong, they told him that the magnets are oreinted 15 degrees with respect to the brushes, making the motor performance asymmetrical. So... I was wrong. Sorry for misleading folks. But... I am still of the opinion that this is not such a big deal. Again, I believe driver skill can compensate very effectively. Yet... I have to confess that because the design on Chief Delphi 6 is such that we can change the motor orientation without changing any parts, we will probably have them installed to run in the same direction. Bottom line: If it is easy, I say do it. If it is hard, I say don't bother. Joe J. P.S. I KNEW that I should never take sides against The Heros of Tomorrow (and especially Mike Gray & Jim Meyer) and/or Raul-the-Magnificent -- ah well, live and learn. P.P.S. I am going to try to get Johnson to give me the CCW and CW motor curves. I am very curious to see the differences on paper. |
