If you're in residential areas, you're most likely using a = phase converter.   I'm getting mixed messages from a couple competent electricians - both familiar with pipe organs - on whether or not this is a safe approach.   I e-mailed two guys from the archives of 2000 (Brian Graham: = bgraham@geat.com and VEAGUE: dutchorgan@svs.net) to ask about their installations and both = of these e-mail addresses are no longer valid.   I would greatly appreciate it if some of you would post the specifics of = your hook-ups.   My motor is a 1926 Woods, 2hp, 220v, 3-phase, 1200 rpm, 5.75 FLRA motor.   Thanks, Keith Zimmerman Commerce, Georgia

Your message doesn't specifically say whether or not the motor was re-wound, and if you're still running on the 'old' windings, there may be some issues. Nevertheless, have a look. I like the VFD concept quite a = bit, though since my blower motor is single phase, I probably won't be trying a VFD myself! :-)   Hope this helps.   Frank Vanaman Baltimore

Personal opinion here, but backed by about 30 years of experience. I worked with 3-phase power extensively on the job (telephone =   company power generation/use), and it's MUCH easier than single-phase to deal with. As far as the converter goes, I had a friend who was running a =   large (27-rank) theatre organ with a 10hp Spencer blower with a Woods 3-phase motor. He was running it with a static (transformer-type) converter, and it ran just fine, for many years. You must be careful to =   size the converter large enough to handle the starting and heavy running loads (many stops on, much wind use), and make sure that the mains are heavy enough to handle the electrical load, and you will be just fine. I think that most who are leery of this approach are those who have little experience with 3-phase. Make sure that you have adequately sized leads and supply. It works fine. Go for it!   At 08:46 AM 8/24/2003 -0400, Kzimmer0817@aol.com wrote: >Organ guys, > >I just got my 3-phase motor from the shop.

Not sure what year, but most likely = 20's vintage.   I'm still having good luck with the phase converter that I got from = Grizzly.   -Brian Graham -----Original Message----- From: DIYAPASON-L@pipechat.org [mailto:DIYAPASON-L@pipechat.org]On = Behalf Of Kzimmer0817@aol.com Sent: Sunday, August 24, 2003 5:47 AM To: diyapason-l@pipechat.org Subject: [Residence Organs] Phase Converters     Organ guys,   I just got my 3-phase motor from the shop.

The company sent me a condenser with easy instructions on how to install it, taking just a few seconds. The second blower is a BOB from about 1932. An electrical company got me a thingie (phase converter? - I'm no electrician) that is plugged between = the wall socket and the blower.   The two blowers going together, totalling about 1.8 hp, draw only about = 1600 watts so can be used from just one wall socket. (In NZ, we have 220 = volts).   My two blowers needed no re-wiring or alterations whatever to the motor. They are very efficient and exceptionally quiet.   Ross
