General Discussions / Re: VEC300 with 5kW motor
« Last post by Corchard on June 21, 2024, 08:58:19 PM »
Hello Again Forum....

I'm still struggling with the setup and am trying yet another route.   I've purchase the Thumb Throttle for external controllers https://goldenmotor.bike/product/48v-thumb-throttle-for-external-controllers/ and just trying to confirm the wiring to the vec300.

The three sets of connectors:

throttle wire             Controller wire            notes         
Red                            Red                           Throttle +5v
Black                          Black                         Throttle Ground
White                        Green                        Throttle signal

Brown                        ??
Yellow                        ??

Green                        Battery +                  Optional battery monitor LED 48V
Black                         Ground                      Optional ground  for above

Are the brown and yellow intended to switch the controller power  (Elock orange , Battery + Red)?  Is it optional?

Is this a hall sensor device or potentiometer for the Throttle mode selection?

And I swear that I tried to determine the answers in this forum or from the online documentation but couldn't find what I needed.

Vec500...try turning throttle to 0-position (12 o'clock). Then e-lock off and again on. Then try to reverse. This works in my solution.

Needing to do that kind of a manoeuvre in order to brake sounds like a recipe for disaster when trying to dock in bad weather.

Hi,

Please see attached pic of Grin Simulator Motor Parameters.
I would like to simulate 3 KW and 5KW BLDC Motor Air Cooled using Grin Simulator.
EZkontrol BLDC Controllers
Require motor and controller parameters?

Thanks,

Hi Alan,

thanks a lot for your very detailed reply! This reply contains what I need for proceeding with this project. I will test this during the upcoming weeks and will keep you posted about the results.

I will for sure measure the cables and connections to make sure that everything will be connected correctly.

Thanks again for your help!

Best regards,
Rickard

Electric Boat Conversions / EzKontroller and regen on a boat
« Last post by Boating Muppet on June 15, 2024, 07:35:32 AM »
Hello. I have installed a 5Kw motor with the B48800 controller as a hybrid drive on a boat. In normal use it drives the propshaft via a belt with the Diesel engine off and in neutral. Control is via a joystick with a centre neutral position and forward and reverse selected by moving the throttle forwards or backwards. At times the Diesel engine will be needed and then the motor needs to act as a generator to charge the batteries. Ideally this charge current will be variable with it reducing at low revs when less engine power is available. It isn’t clear in any of the instructions how to do this. There are various brake inputs and I have seen on the American golden motor bike site reference to an ‘auxiliary throttle’ which appears to be for variable braking but there is no reference to this in the manual, such as it is. Can someone please point me in the right direction. Thank you

Magic Pie & Smart Pie Discussions / Re: Programming cable for Magic Pie II

Hi Rickard andto the forum.

The Magic Pie 5 USB programming lead is only suitable for the vector controllers (MP4 and MP5) which use a different VEC programming software (PI-800), so it is unlikely to work with your MPII controller.

The PI-300I USB programming lead is suitable for the MPIII controller which used the same programming software as the MPII (PD_282_speed).

If you are unable to get hold of the correct USB programming cable, it may be possible to adapt the 8 pin PI-300I programming lead (or the 12 pin PI-200E cable for the external controllers) to work with your MPII, but you would need to be very careful with the conversion connections as the wire colours shown below may not match your particular programming lead as the colours often vary.



If you purchase a 8 pin Mini DIN Extension lead with both male and female connectors, you should be able to cut it in half and splice it into the PI-300I or PI-200E programming cable by connecting the required four wires so that it could also be used for MPIII or external controller programming if necessary. ;)



I would also stagger the joints in the wires similar to the diagram below even though you are only using four of the eight wires:



I recommend that you carry out a simple continuity check to determine what colour wire goes to each of the four programming pins in the connectors to confirm their correct function before trying to reconnect the four wires from the USB cable to your MPII controller harness.



The above wiring diagram should also apply to the MPII harness, but the unused Yellow wire shown is sometimes pre-wired to the throttle switch to operate the Reverse function.

I hope this helps.

Alan

Magic Pie & Smart Pie Discussions / Programming cable for Magic pie 2
« Last post by RickardNilsson on June 13, 2024, 06:14:11 PM »
Hi,

I have four old Magic Pie 2 motor that I need to change the settings for, I'm therefore looking for a way ot program these.

The programmer that was developed for the Magic pie 2 motors is discontinued from golden motors. Has anyone tried to modify the programmer for Magic pie 5 with a contact that fits the Magic Pie 2 and been able to successfully program the controller? Or is there someone who is willing to sell their MP 2 programmer to me? :)

Best regards,
Rickard

Electric Boat Conversions / Re: VEC500 regen on a sailboat? Anyone gotten it to work yet?
« Last post by Pontus on June 11, 2024, 12:22:01 PM »
I did get this to work on my VEC 500, although power was very low at the time; around 190 W when sailing at 6 knots. Bear in mind that this was with a motor directly mounted on the prop shaft - WITHOUT and reduction gear. Unfortunately there doesn't seem to be a way to turn of the cycle of 15-beeps when re-gen is engaged.  :-[

I've now rebuilt the transmission with a reduction gear, and therefore expect higher power, since the motor (generator) will spin faster for the same sailing speed. I would estimate the generated power to be about 500 W, this have to be confirmed with real life tests though.

You can read more about re-gen in this blog post

I have a boat of similar size where I have done the conversion you mention.

It's all quite well documented on the boats web site. although written in Swedish, there's a Google translate button on the page that does a fairly decent job.
