Comentario:	* IMELDA (Imelda Cota) * February 26, 2007 at 10:23am Thursday Jesus is interested in buying at least one manual surge tester to have a repair area. Quote a ST103 and ST106. He also wanted a tutorial on Corona. He did not understand the cause or what they were trying to measure. Jesus then introduced me to Gerardo Rojas (Gerardo.rojas@emotors.com), He is a Quality Engineer. Gerardo is working to implement Corona testing in the plant. They bought a tiny impulse generator and a scope to do some experiments at the request of Duke Snyder a Quality Manager out of St. Louis. They are having a lot of problems with a 6 pole 3 phase motor that they make for Liebert which has no phase insulation. They think corona testing will help. The test they developed uses a few loops of wire as a pickup coil which feeds a scope. They impulse two leads at a time and look at the pickup coil output on a scope. They typically show a CIV of about 2400V on the Liebert stator. When we did the same test on the AST we saw a CIV of about 1500V. The AST results are more consistent with tests Emerson corporate has run using other equipment on the Liebert stator so they were not surprised. I think the difference is that the impulse generator they have is extremely low energy so the amount of Corona generated is much less than the AST. They want to start testing the Liebert stators on the AST even though they are made on a different cell. Duke Snyder was at this plant today so had a chance to talk with him for a while about Baker's Corona test. He seemed interested in what we are doing. He asked me to send him information on our new Windows Corona test capability. Duke suggested that we get in touch with the Quality Manager at Mena, Mike Bailey about Corona also. Lastly, Juan gave me the names of two engineers at Emerson CMD next door. They make multispeed fan motors and so far have been uninterested in talking with us. Juan knows them well and says he will tell them that the AST is better then the Emerson equipment so they should start to talk with us for the future. They are Alfonso Garza, Mfg Eng (alfonso.garza@emotors.com) and David Hernanadez, Winding Sup. (david.hernandezA@emotors.com. Jesus is a brother to Felipe Zamarippa who used to work at USEM. Felipe is at another Emerson motor plant we did not know existed in Monterrey. That plant makes industrial gear motors. They do the mechanical fab and the assemblies but make no motors. Jesus says they need an analog tester for incoming inspection. Felipe's email is felipe.zamarripa@emerson-ept.com. This plant is in the Prologis Monterrey Industrial Park on the south side of the road between the airport and MMM. I drove by. There is a huge Denso plant next door. Need to find out what they do.
