I want to use an A/C gear motor, but need speed controll ability to
obtain 20 -35rpm continuous. A dimmer switch might overheat and not
regulate properly.
D/C motors are not expensive, but the controllers w/voltage
regualators are a killer.
I found an old Lionel transformer, 50 watts. 120 volt-60 cyc.
Seconary voltage 8-15 V.
Would this transformer accuratly control the speed of a typical A/C
gear motor, that has a fixed RPM at around 40?
Thanks.
