Yaesu G-5500 Azimuth Motor Replacement
Dear All,
Greetings from Kuala Lumpur, Malaysia.
I have a Yaesu G-5500 rotator that has a spoilt azimuth motor while the elevation motor works fine. Looking at the specifications published by Yaesu, the G-800 rotator seems to be very similar with the azimuth motor of the G-5500.
Instead of purchasing a whole new set of G-5500 just to replace the spoilt azimuth motor (the control box is working and this has been verified with another working azimuth motor), I wonder if anyone has tried replacing the azimuth motor the G-800 instead?
Will the G-5500 control box work with the G-800 motor, are there some modifications needed, or is this simply not possible? Any pointers will be greatly appreciated.
Thank you.

Sion,
What is the exact issue with azimuth unit.

Something similar happened to me when I broke down 5500, I bought a G1000 and I could not use, lead different voltages, I can not give more details now. Check before online manuals. 73's Luis EC4TR

Sion,
I don't own a G-5500, but I do have both a G-5400 and G-800. The G-5400 and G-5500 are similar (not identical) judging from the manuals.
From looking at the manual for the G-5500, the azimuth rotor is completely
different from the G-800. The G-5500 (and the G-5400) azimuth rotor is an AC motor with two coils and three wires for the motor. The G-800 is a DC motor with only two wires. (Both systems use an additional 3 wires for the position potentiometer, so five wires for the G-800 and six wires for the G-5400/G-5500.)
The G-450A rotor is similar to the azimuth half of the G-5500, judging from the manual. However, I'd look for someone who owns a G-450A who can verify that for you. The G-450A manual omits a schematic and some important specifications like the motor voltage. You may also be able to get some help from Yaesu customer service.

Dear All,
Thank you for all the replies to this topic which is greatly appreciated.
In conclusion, I guess I will have to either (1) Replace the azimuth portion with a G-800 using a seperate control box for azimuth and elevation or (2) try to replace the azimuth portion with a G-450 rotor.
Has anyone successfully tried connecting the G-450 rotor motor directly to the G-5500 control box?

Or:
(3) Purchase a replacement G5500 Az motor from Yaesu (they should be back in stock now?)
(4) Send the problem motor to a motor repair / rewind company (maybe a few hundred $)
(5) Rewind the motor yourself (doable, but it takes a while)
Good luck, and 73! -Dave KB5WIA
