General Discussions / Eggrider Question
« Last post by Chuy on January 06, 2024, 04:08:15 AM »
Howdy, new member here. I bought an Eggrider V2 from Goldenmotor and it has been great overall. My one issue is correcting the odometer reading so it displays correctly without having to adjust it using the Odo Offset in advance settings. The manual states updating the wheel size setting corrects the speed. I don't see what setting corrects the odometer. It shows less miles than I am actually covering, per two gps apps on my phone.

Hi Renaud andto the forum.

As you are using BAC0281 controllers, you will need to use the earlier PD_282 Programming software, and with this software, the programming is usually carried out with the battery disconnected (or turned OFF on the battery switch if applicable).

Please read the following installation instructions, especially if you are experiencing problem reopening the software after saving changes:

On some controllers, the gate connection was internally bridged, which means the controller will remain active while the battery power is turned ON.
I suggest switching the throttle signal wires to enable/disable the motors.
The following diagram should also work for the external BAC0281 controllers:



The 12K resistors were required for some Magic Pies to prevent a throttle error when the throttle signal wire was open circuit, but I'm not sure if the BAC0281 controllers will suffer from the same problem.

If you are running both controller from a single throttle, make sure that the +5V supply from both controllers are not joined together, as this can sometimes cause problems.

As one of your controllers works OK and the other does not, it could be incorrect settings in the controller or possible different wiring or even a faulty controller.

Make sure the non-working controller is programmed the same as the working one and then swap the controller wiring harness if necessary.
If the non-working controller doesn't work with the working program parameters and wiring harness, then the controller is probably faulty. :(

Hi
I'm working on a twin motor bike my father started 10 years ago . My father passed away 2 years ago and I would like to finish that project
He was using 2 controllers BAC0281 with 2 GM 250W - I'm looking after the software that I can use to review the setup of the controller
Which software do I use best - Magic Pi3 , Edge ,4,5 ?
When using the software and connecting the controller with the USB cable , do I need to connect any other power source (B-B+ or H+H-) on controller or the controller will get his power from the USB cable ?

I have also installed 2 switches so I can drive either with front or rear or both engines
I'm using contact G (Gate) on the controller to switch off each engine - is that correct - it doesn't seems to stop the engine ?

I managed to have front engine working when connected to controller 1 but then rear engine on controller 2 doesn't work. When I connect rear engine to controller 1 then it works but front engine on controller 2 will not work.
So I'm sure both engines & cabling are fine but suspect maybe a controller 2 config conflict.
The brake switch works fine and open or shut contact between B, Z oV

Any suggestions ?

Tx Renaud

I don't know where this year has gone, but we're nearly at the end of it already.



I hope none of you are on Santa's "Naughty" list this year and that you all have a wonderful Christmas time.

Hi Jon,

I'm not aware of any updates for the Vector controllers that would actually reduce the motor noise.

The VEC controllers are Sine Wave controller and they greatly reduce the motor noise under load compared to the HPC square wave controllers.
I suspect that the noise you are hearing is the typical motor noise which occurs when you manually spin the motor (without using power from the controller), so it is unlikely that you will be able to reduce it.

It might be different if the noise was only evident while the motor was under load, but if the motor is still producing the noise while it slows down after quickly releasing the throttle, then the controller is unlikely to be causing it.

Electric Boat Conversions / Noisy 5kw motor and VEC300 controller
« Last post by JonS on December 24, 2023, 01:12:37 AM »
My motor is really noisy when it runs at all speeds. The noise is not mechanical. It has that noise that servo motors often have. Does anyone know if there is an update for the VEC300 that makes it quieter?
thanks

Hi Wayne andto the forum.

Unfortunately, I think that those questions will need to be answered by Golden Motor in China (sales@goldenmotor.com) because it is unlikely that forum members will have access to the information you are seeking.

If you are able to obtain the required answers from GM direct, please post them here for the benefit of future customers who may be looking for the same information.

Electric Boat Conversions / EZ Outboards 20HP

Hi
I am busy testing an EZ X20 outboard and would like to know the following :

1. Is it possible to get a different pitch propeller ? Currently delivered with a 10 inch and looking for a 12 inch ?

2. Can the EZ outboard app be updated so that the used w/h is included in the spreadsheet download ?
 
Thanks

I'm skeptical about getting the cover off but I will prevail. I must. No Fear.

In case I wasn't clear, the Magic Pie IV is only the hub no spokes/wheel.
