Electrics & Radio Gear / Re: Truckable Towboat With Motor Noise.

Ok,  I disconnected the motor ECS is fine, its the motor.  Guess I will wait and see if the new gear motor makes any noise.  I know when I was into RC trucks, you had to solder a capacitor on the motor.  Wonder if that might work.  Gotta dig through some stuff to see if I have any.  Steve

Appreciate the info Des.  Going to disconnect the motor now and see what I find.  I have ordered another motor.  One for robots with a gear drive, so slower rpm's. 
Will let you all know what I find when the motor is disconnected.

The noise could be from either your motor or your ESC, but generally a high-pitched noise (whistle, or whine) it is probably more likely due to the electronics used within the ESC.  As Olscuzbut suggests, try the motor connected directly to the battery.  You could also try operating the speed control for the ESC, either without the motor connected, or with another motor.

If the noise is associated with the motor, and you have just applied a small amount of throttle, I would expect either no noise, or a lower pitched noise, as the motor would be either still stationary with slight humming (low pitched), or just breaking away.

A high pitched noise from the ESC is likely to be resonance from the switch-mode oscillator;  noise suppression capacitors connected across the motor terminals may help, but also may not be entirely effective either.  (You will need someone with more expertise than myself to recommend appropriate capacitors.)

Could be normal depending on the ESC you are using.  Do you get the same noise if  you connect the motor directly to the battery?

Electrics & Radio Gear / Truckable Towboat With Motor Noise.

Hello Everyone,  I am back, and have started a small tug build. 
Working on a small (about 9') truckable towboat.  Everything is wired up, and I am getting this high pitch noise as soon as I give some throttle.  I asked at the hobby store where I bought the motor, and he said it was the motor and the nature of the beast.
Was wondering if any of you have run across this, and if there is a salutation to the problem.  Thanks, Steve

Hi again everyone, if anyone has a small graupner voith unit 1768 that use to work in the Thysen ll,
Could you let me know? I'm still looking for one or two preferably.
Thanks.

Let me know what you want details on.

Thanks Toby, we can continue in English this is for sure not an issue for me.
Let me know if you want to get specific details on how it's done at the back end.

I can start for example with the top cabin screens animation. You might have seen that the screens are animated:

It's in fact a single 0.91" oled screen with an I2C connection to an arduino nano. It's the 3D printed part which makes it 3 screens.
I've done 3 animations on it using an Arduino Nano:
 - radar which rotates with each dot becoming bigger when the line goes above it like seen on the movies ;-)
 - the second screen is linked to the boat motor and rudder position. The top "slider" is the position of the ruder. The left "slider" is for the propulsion, centered the propulsion is stopped, going up the propulsion is forward, going down the propulsion is backward. The milddle "counter" represents the motor RPM. All these animations really works along with the boat, if you move the ruder on the remote control it does move the slider at the same time as the servo, same goes for the motor.
 - the 3rd screen flicks betwen GPS and depth. The depth is displayed along with random fishes for fun. The GPS is a map with an animated triangle showing the boat position.
You can see it live in this video:

Pascal Je vais maintenant regarder vos autres vidéos YouTube. Je trouve cela très intéressant. Je suis désolé si mon français n'est pas bon, mais l'allemand est ma deuxième langue.

Cordialement

Toby

 Très bon!

Magnifique!

This was very interesting to watch and see the achievement that can be had. I liked the officer being able to raise his binoculars and the other deck hand moving. It helps to see what may be available for other motion on other vessels from tugs to warships. Making landing craft work...4 in my HMS Intrepid 1:96 model progressing not finished.  Making 1:48 and 1:96 helicopters operate for warships and the likes of working davits and anchor winches and the crane on my Vliestroom buoy laying ship.

Clearly you are  great at electronics and programming. I wish that I were too but at present not. Always interested in the how's of such things.  So keep posting and sharing your great ideas.

Toby
