Hi Jim....
I am presently using 4 of the DC versions for my rotating towers.
Instead of the M2 controllers tho, I am using the Green Herons.
Jeff at Green Heron convinced me that the DC motor is the overwhelming
choice for rotor control.
I did not get into the 'why' part, but figured since he was a major
contester and designer of things electrical and mechanical that his advice
might bode well for me.
Since my rotators are at the bottom of my towers and because I am using PVC
weatherproof boxes for joining the rotor pigtails to my shack control cable,
the length of the pigtails are/were entirely satisfactory.
Best,
Dick, K5AND

Subject: [TowerTalk] OR-2800 motor.. DC vs AC ?
I have 2 of these OR-2800 rotor's. The original one has the AC motor, and
has never been used.
The 2nd one I bought used, and am 99% sure it has the DC motor in it.
I Dunno if the 2 x mating controller's are interchangeable or not ? I
like the pulse width modulated
motor control feature.. you can slow it right down to a crawl. If the 2 x
controller's are not interchangeable,
I'm sure the green heron controller will handle either the DC or AC motor ?
The idea here was I only require one rotor on the new tower, and the 2nd
OR-2800 was to be a spare.
Has anybody compared the torque of the AC vs DC version ?? Is it
worth having M2 retrofitting
the DC motor into my older AC version ? One thing I don't like is the
very short 'pigtails' coming out
of the rotor itself. They should have made em longer.. like 10' at least.
Then splice them at a junction
box, [ which I see they now have]. The original twist locking splice was a
dead loss.
The new water proof junction box would make for any trbl shooting, a lot
easier.
Any thoughts would be appreciated.
later.. Jim VE7RF
