[amsat-bb] Re: G5500 Rotor motor Question

[David Palmer KB5WIA]

Oh, I didn't measure the rotation speed of the motor during my rebuild,
unfortunately.  In all the research I did prior to the rebuild (=scrambling
to find an equivalent motor) I didn't see any published specs on the unit
either.  I'd think Domenico's calculations would probably be the closest,
since it is a simple 2-pole AC motor.
