I'm pleased to hear that you've got both motors working, but the 902 mini motors are unable to produce any torque in reverse due to the internal unidirectional clutch.

Without know what voltage motors and battery you are using it is difficult to know what the best settings will be, but I would not set them anywhere near the controller's maximum settings as passing too much current through the mini motors can strip the teeth off the nylon gears and also overheat the windings, which sometimes melts the insulation on the wires resulting in a short circuits:



Drawing just 10 amps at 36 volts (or 15 amps at 24 volts) equates to 360 watts, which should produce an output power of 288 watts at 80% motor efficiency, which is already more than the 250 watt rated power for the mini motors.

However, I suspect that your smaller diameter wheels and dual motors will be less susceptible to overheating as they should be under a lot less load than an identical single motor in a larger diameter wheel.

Hi Alan

Tx a million for your guidance

I managed to connect to both controllers using the right software and once I had set the same settings ,both engines started to work together.

I'm currently doing 5 full cycles of charge and discharge to break in the new battery. I was told to do 5 full cycles in totals before settings the Amp back from 5 to 30 continuous and from 20 to 50 peak in the controller config
Do you agree with that ?

Once I have done the break in of the battery I will give it a try at your suggestion to use the throttle wiring instead to use one or 2 engines or both

The reverse switch on the Accel switch is also not working although both controllers have the reverse switch set to enable and I tried - immed and unimmed mode without luck - any thoughts, not that a must have but just fun :-)

Need to fix the rear suspension as the rear shock doesn't seem to coop with my weight. Seems to loose air pressure. I will install another one to see if better

For the rest happy I managed to get it working. The pic of the beast :-)

Hi andto the forum.

That throttle should work fine with an output voltage is 0~5V.

The Orange e-lock wire simply requires battery voltage to be applied via a switch to activate the controller, opening the circuit disables the controller.

Reverse is achieved by switching the Reverse wire to ground.

The diagrams below will hopefully help you identify the connections required in order to plan your wiring harness:

I did that first, my measurement is 2045. I’ve changed it up to 2065 and have not noticed a change in odometer readout. It has corrected speed reading. I will try larger increments.

General Discussions / VEC300 with 5kW motor
« Last post by Corchard on January 15, 2024, 09:28:35 PM »
Hello Forum,
     I just recently vector 300 w 5km Air cooled and am trying to desk test it before I install it in my sailboat.   I'm trying to determine how (if) I can use a ET-134 throttle controller instead of the rather large heavy one that Golden motors has for sailboats.

the et-134 has 48V input which I can get from batteries (switched and fused) and produces the  0-5V necessary Green-white throttle wire.  So far I haven't been able to get the motor to move.   What else is the controller expecting and on what wire? What signals are required to indicate reverse?   

In terms of shutting down the controller, is the e-lock (Orange wire) just a switch (closed/open circuit)? or is it expecting a signal of some sort?

Unfortunately the vector controllers don't have a proper schematic for the control wires that I have found so that I can plan my wiring harness.

Any help that anyone can provide would be useful.

Is the lower arm always horizontal?

Chainstays typically slope downwards slightly towards the bottom bracket:



But here are a couple of exceptions:





The angle between the seat stays and the chainstays can also vary significantly on non-suspension frames.

I've been told there are adapter brackets available for frames without discs.  Any input on that avenue?

You obviously didn't click on the hyperlink in my initial reply to this bolt on adapter kit or you would have seen this adapter bracket:



As previously mentioned, I have not tried any of these kits and I'm not sure how suitable they would be for your particular frame or for use with a 14mm diameter axle.

I think this drop out works with the adapter.  it might need a little widening though.

Mark, the holes in the frame bracket are not threaded, they are just clearance holes for the M6 bolts that pass through them and then thread into the caliper mounting piece:



Please note that you only need to fabricate the section shown in blue (not the entire bracket) and it may have to be shaped differently to fit your particular frame:



Here's an example of a different bracket shape:



The most important thing to get right is the distance between the two 6mm mounting holes and the distance of each of these holes relative to the centre of your axle.
Please note that the centre of your 14mm diameter axle is likely to be at least 2mm lower than the one shown in the dropout above for a standard 10mm axle (unless you have already filed 2mm into the dropouts)

This is really good.  If I can make this bracket.  I assume the holes are to be threaded, of course and probably 0.125" thick and like brazen in place. I'm seeing an opportunity for something new and creative with a washer or two for good luck.   Randy says brakes are over rated.  Ha Ha.

The light/horn needs a mount on the stem tube or fork. 

with gratitude. Mark.
