Your comments and questions to the Videos were the inspiration
to to give a very rough outline about the electrical functions on board our ships.
if you´ve got further questions,
please write them down into the comments-box.
we will try to answer them in one of the next clips,
...at least, as far as we are able to :-)
We brought different models of our fleet...
in terms of electrics they differ in the amount of various functions they are performing.
Here, we got a motor and the steering-function.
Here we have motor, steering and a working crane,
a radar, wich turns,
and lights wich can be switched on and off.
Here in the AZIZ we already have two propellers, two motors,...
wich are independently controllable,
so we also have to feature two channels on our remotecontrol. One for each motor,
to steer them seperately.
Then we got the bow-stream-rudder, the hole there in the bow,
where water get´s pressed out to the one or other side, to move the bow sideways.
and of course we got the rudder in the rear,
the ship get´s navigated with in normal sail.
Alltogether, only on sailing-functions we count: motor, motor, steering und bowstreamrudder ...4!
We start our Tour here in the accubay, it holds
our energy source secure in place. There are different kinds of power sources:
it can be put together from a lot of small cells,
the most common one is the lead-acid block and
today you´ll find more and more the "Lithium-Polymer"-Battery.
Using this one you should take great care in carefull handling and be sure to carry and store them
in a safe bag. They concentrate a lot of energy in a small space and if they got damaged, they even...
...may ignite or explode.
So take care when using them.
So,.. here the engergy enters our circuit.
Passing on to two appliances,...
... on the one hand the receiver,...
It´s job on board is to transcript the radio signals into commands for the appliances -
These commands control the electronic Speed controller - who itself controlls the motor -
and the Rudderservo wich controlls the steering of our boat.
The speed controller also needs power to drive the motor.
This is the cable connecting the Controller with the motor here. Depending on the
power and polarity emitted by the controller, the motor with the propellor turns right or left,
fast or slow and drives the boat this way.
The Receiver receives the Signals our Transmitter is emitting and seperates them
into different steeringchannels. In this case into one channel for the speed-controller...
... and into a second channel for the steering-Servo.
The Steeringservo then sets the Rudder depending on the lever-position of the transmitter.
This way our boat can sail small or big circles or correct it´s course.
What else is important?
Here, soldered on to the motor, you can see small capacitors.
Those are there to reduce radiointerferences at the receiver caused by brushed motors.
You can buy ready packed sets at modelshops or the single capacitors at electronic sellers.
You should not omit them,.. even not at very small motors!
Otherwise Problems will be pre-programmed.
"Servos"... occure in different sizes, prices, settingspeeds, as digital or analog ones.
It´s the same with the speed controllers. You find them for cars, planes and more rare, for boats.
all differently suited.
There are quite small controllers. This is actually the whole controller!
and there are controllers for different types of electromotors.
Brushless Motorcontrollers need three connectors, as you can see here.
This one even has a watercooling-connection. This is where the accu gots connected...
... here it receives it´s commands.
In oppisite to the brushless Motors with three connectors,...
the conventional Motors with coalbrushes only have two pins. Plus and Minus.
You will also find a lot of different receiver working on different frequenzies in Giga- or Megahertz.
The most common ones today are the 2.4 Ghz-receiver.
Important is,.. they got to match the transmitter in frequenz and transmitting protocoll.
We will get back to this in the next episode.
That´s it for this time,...
in the next clips we will have a look into our KORMORAN as well, as in the a bit bigger Models..
like the SEABEX ONE and the AZIZ.
We will also have a short overview about the radio-controllers!
If you´ve got further questions...
- and I´m sure you have :-) as this was only a very rough summary -
...then put them down into the commentsbox,...
and we will try to answer them in the next parts.
Thanks for watching,...
If you liked it, we are glad if you donate us a "thump up".
