There is one "gotcha" to all this. In 2019, Yaesu changed to using DC on
the rotors. From DX-Engineering " Instead of the usual AC motor drive
used in older rotator designs, the G-2800DXA, G-1000DXA and G-800DXA use a
variable-voltage DC motor, removing the need for a large starting capacitor
with its potential for failure exposed to outside temperature variations.
" The 450 and the 5500 are the same way.
There might be an easy way to determine the AC vs DC upon inspection. I
haven't looked at all the manuals to confirm this but at least with the
450, it uses only four wires for DC types. Otherwise, some of the models
are stamped with a "DC" after the model number eg. " For clarity, the new
DC rotator motors are marked "G-450DC" at the connector. The rear panel of
the controller is titled "G-450ADC" on the serial number label."
