[GreenKeys] Model 28 Bell, electrical perspective

[ad7i]

Greetings All --

I recall from previous GreenKeys discussions that the electric bell in the
model 28 cabinet is intended to be driven with 120 VAC 60 Hz (normal house
AC power).

Does anyone know if electromagnet in the bell assembly makes use of a
shaded poll?   I assume that the duration of the power applied to the bell
electromagnet is determined by the operation of the stunt box (i.e, does
not exceed the time to receive one character, about 163 ms at 60 WPM, about
98 ms at 100 WPM).

Is there a possibility of burnout of the bell electromagnet coil if the
power was applied to the electromagnet for an extended period of time?

Thanks,

Paul, ad7i
