[Phono-L] Electric Motors in Phonographs
As I mentioned elsewhere, every one of the universal motors I've ever heard were noisy things, very noisy. Edison used his own brand of motor and I'm not sure what Victor or others used but they were of different design but still noisy. It seems like they would have been more of a novelty for the wealthy. The Induction motor was a different story. Every one of those I've seen were made by G.E. including those used in Edison and Victor machines, and possibly others as well. They are noiseless compared to a universal motor. I'd be interested to know of any other brands of induction motors that were used in machines of the day. Bruce

One other supplier of phono motors in the late twenties was Bodine Electric Co., of Chicago. Majestic used them in their electric players in the late twenties. I believe that Capehart also used them. I don't know when they started, but General Industries, of ERlyria, Ohio did a lot of governor cotrolloed induction motors in the thirties. their brand name was Flyer. The motors were gear drive to the turntable spindle and could be had in 78 or 3 1/3 only or 78-331/3 with a gearshift. they were very popular with custom phonographs. - Original Message - From: Bruce Mercer maxbu...@sigecom.net To: phono-l@oldcrank.org Sent: Wednesday, May 03, 2006 4:16 PM Subject: [Phono-L] Electric Motors in Phonographs As I mentioned elsewhere, every one of the universal motors I've ever heard were noisy things, very noisy.

You gottum correct. The induction disc motor was a GE product. It operated on the same principle as a watthour meter does. It had a governor to limit its shaft speed to record playiung speed. Its torque was mild, but was boosted with the use of a phase shift capacitor in some applications. This made it possible for that motor to drive the early Victor record changers, and also to pull the turntables with the home recorders that RCA was selling. - Original Message - From: Robert Wright esrobe...@hotmail.com To: Antique Phonograph List phono-l@oldcrank.org Sent: Wednesday, May 03, 2006 5:42 PM Subject: Re: [Phono-L] Electric Motors in Phonographs So I'm thinking my Brunswick Panatrope with its noiseless motor bearing both GE and RCA markings must've been Induction-type, then. I'm no electrical engineering guy or anything, and I didn't know another type of electrical motor ever existed. I also didn't know there had ever been a 450 gpi cylinder experiment in 1899. This is the technical oddity stuff that sends me flying! What all is known about it? Anyone have any detailed pics of the C-1 or C-2 pickup? Or either machine, for that matter? Is there a collection of Edison machine photos online someone might link us to? Great info, Bruce, thanks so much!
