Electric Motors for Player Pianos & Orchestrions
By Robbie Rhodes

I'm interested in the various old motors installed in player pianos and
nickelodeons and orchestrions.  I placed a web page, "Electric Motors
for Player Pianos", with a representative drawing of the Holtzer-Cabot
frame style ST 18 motor (3.5 amps) I acquired recently, at

In MMD I found references to these different motors:

In 000129 MMDigest:
> Holtzer-Cabot 110 VAC, 3.2A, 60 Hz, 1150 rpm, Frame OS 16,
> Motor #555791.  Mounting hole centerlines: left-to-right 4-1/2",
> front-to-rear 4-3/4".

In 001029 MMDigest:
> Holtzer-Cabot 110 VAC, 2.3A, 60 Hz, 1150 rpm (in Welte-Mignon)

I'd like to make a list with descriptive drawings of these other
motors, too, and also for the Emerson motors often found in Seeburg

The general question to be answered by the web page is the one asked
by the owner of an instrument without a motor: "What size motor is
needed in my instrument?"  (My motor illustrated at the web page,
rated at 3.5 amperes, might be bigger than typical for a player
piano; maybe it formerly powered an orchestrion.)  Please write to
me if you can provide information.
