General Discussions / Merry Christmas everyone
« Last post by Bikemad on December 24, 2023, 07:26:26 PM »
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.

Electric Boat Conversions / Re: Electric dinghy using a 5kw motor and VEC300 controller connected to a waverunner (jetski) pump

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
« Last post by Future Marine on December 17, 2023, 11:51:44 PM »
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.

I'm a little bit nervous about the next step.  Removing the stator assy from the new MP4, tell me it comes off easy.  So after I get the cover separated from the hub, I can continue around the hub all the way without pounding or is the magnet force too strong?

I would simply install the new stator assembly into the old magnet ring as it's a lot easier and quicker than swapping the rim and spokes and then having to true the rim and then re-tension the spokes after the first few rides.

The only damage that can sometimes occur when swapping the stators is if the laminations catch on the magnets while removing the stator.



If this happens, you can simply clamp them back into their correct position and apply some superglue to ensure they stay in the correct place.

Now the big question.  To replace the Magic Pies with the wheel on or re-spoke the hub. Should I risk possible damages to change the stator assembly or just find a mechanic who can re-spoke the rim onto the new Magic Pie IV?  I'm thinking the latter...
