Never got one response, But here's the answer

[Honest John]

Posted twice a question regarding reversing the rotation of
a Novak SS5800. Never got one response.
If anyone give a crap, here is the answer quoted from the
E mail I finally got from Novak.
<SNIP>
No, it takes much more then just switching the wires, we have to make
special software for them to run reverse rotation.

Please let me know if you have any further questions, we are glad to help.

Thanks for the forward. A lot of people simply won't reply if they
don't know the answer. I think you simply stumped us.

I agree with Justin
It's better to get no answers, than a bunch of wild un-educated guesses.
I did hear in another forum, that the ss5800 has some hard advance
timing built into the motor, between the Hall sensors and the field
coils. So you can't just change two of the power wires and two of the
sensor wires to reverse it.

[the_atomic_punk]

Apparently they did not tell you how neither,maybe it cannot be done
and that is why no one bothered to answer.What is the application
needed for the reverse rotation?

[Honest John]

Thanks guys.
I thought no one liked me.

In my aircraft that run brushless, if you add a gear reduction
unit, or switch to a pusher setup, you can reverse motor
rotation by switching any two power wires.
This is easy and commonly done as long as there are not
rotor position sensors. (As I know now).
I have a Aveox brushless in a plane that has a sensor for
locked rotor only. It can be reversed. Locked rotor
protection is important for belly landings or any time
the prop can hit or get stuck on something.

The reason I was asking was for potential use of two
SS5800 used in a Clod or some type of truck.
One motor has to run reversed. I don't really have a
specific use planned, was just thinking about possible
uses for the two I have now. Maybe I will use a dog gear
and run them in my Villain.

Just read the RC Car Action article about Kevin trying
to put one in his Bruiser. He struck out too. Oh well.

When a speed controller provides its current output does it not throw
it + and - polarity?
Can you just reverse the polarity of the motor? And if not can you just
change the leads on the armature to th commutator? (Reversing the wind)
If it is coreless(brushless)maybe you can reverse the wind on the
stador or 180 degree the magnets? (depending on what size and type of
motor.
I hope this helps.
I am a member of EASA (electrical apparatus service association) and i
could ask them if nessicary.
Really do not understand why no one else would help?Possibly because of
the influx of all the forums and msg boards makes this group a
dinosour.:-)
But anyway i still watch this group.

The brushless motors need a three phase supply to work so simply reversing
the polarity of the wires will not help (the 3 coils fire in a sequence), as
John said the sensors are probably hard wired for mechanical advace in one
direction. The magnets are on the rotor in a brushless motor so you can't
easily change them and that wouldn't make any difference to the rotation
only changing the firing pulses going to the coils will do that.

I suppose you could probably do it by opening the motor and rewiring the
sensors but it'd be a fudge at best and probably require a new PCB for them
to sit on and then you'd need to adjust the programming of the controller to
account for the advance now being retardation.

Still I suppose Novak could come up with a kit to do it consisting of a new
sensor board, instructions to change the wiring and new software for the
controller but the potential sales are likeley to make that a non starter.

Chris hit it on the head. I have been using brushless motors
for many years. I am a woodworker. Nearly all the tools
in my shop are three-phase. Every time I install a new machine
in the shop, I have a fifty-fifty chance of the motor running
backwards. If it does, I just switch the two "hots" and all
is well. I have done the same with my planes.

There simply is no need to go through with modifing the
Novak system I have. Quite frankly, It was just a whim,
just a thought that ran away from me. Today I installed
one of the SS5800 set-ups in my XXX buggy.
The snow is mostly gone here in Milwaukee and the sand
at the beach has been calling to me. Paddle tires are mounted
and the sealed motor works hard and shrugs off the sand.
It is a great set-up dune running.

The other SS5800 box is still looking for a home. not sure
what vehicle gets it.

Why are the Web TV guy the ones no one can understand?
(Troll?)

[Chris Dugan]

John,
couldn't you try to fabricate a mount to fix the motor to the opposite side
of the gearbox in the Clod/truck?

If you have a machine shop it's not too difficult to re-drill the mounts all
the way through and create a support structure for the motor providing it's
not going to interfere with the suspension, I can't help much as it's been a
long time since i've seen a Clod. Another idea to try would be to rotate the
gearbox 180 degrees, I saw that done to a Schumacher Cougar in the 90's and
an RC10 in the 80's to improve the weight distribution.

[Honest John]

'Suppose I could, I also think someone makes a dog gear attachment for the
clod that lets both motors run in the normal
direction.
But as I said in last post, I am not going to. Truth is, things
have changed a lot over the Easter weekend.
I sold the old Clod Buster on Saturday. Gone! Also...
The weather has finally got warmer here in Beer Town.
The sand at the beach is mostly exposed and dry,
I have mounted one SS5800 in my XXX buggy,
the other is in my XXXT. Both have paddles mounted and
ready for action. Just got a touch of the flu left now, a day
or two and I should be at the beach. Hope the weather holds out.
I will post a few pix in the binaries groups of the sand beasts.
