Hi Crossbreak. Can you read my PM? They hasn't been sent from Outbox for unknown reasons.

Re: New Approach to 4500W Mid Drive

Before you wrote the gear set is capable 160NM.
Any deadlines when the mid drive set will be made?
Do you prefer making it for yourself only or as GB?

Re: New Approach to 4500W Mid Drive

Perhaps better to use APS8072 50KV for enough power without too much heat build up. With planetary reduction gear you can reconsider belt drive or direct belt left side drive. Also freewheel should be implemented to the motor. Chain combined with planetary gear will produce too much noise from the s...

Triangle Battery Pack Design Architecture Configuration

Hi.
I've designed some examples of triangle battery for my ebike project.
Please give me your thoughts which variant is the best for current sharing and reliability.
Sorry for the ugly pics, at least they are comprehensible.
Thanks.

Re: GNG X1-pro 3000w

they want you personally to declare the value and pay a tax for imported goods. You should say it's a sample or gift to avoid it if motor comes with the same supporting documents :)
Waiting for your first impressions btw.

Re: Direct-Drive conversion of the new GNG/cycmotor X1-pro 3000w

Hi Crossbreak. Will you send me CAD drawing for this project? Using 13 - 14T front sprocket result in even lower speed than with 18T you are currently using if rear sprocket remains the same. To raise the speed ScooterMan need to lower teeth count on rear cog or raise them on front cog or both varia...

Re: Direct-Drive conversion of the new GNG/cycmotor X1-pro 3000w

I'm going to use Cube Hyde Pro frame for this project. Is it stiff enough? We can use 8M15 belt, but will it survive with 180nm of torque? I guess belt drive is superior to chain drive in any way if it's done properly, considering also zero noise level from belt. Chain 18T-36T reduction to belt driv...

Re: Direct-Drive conversion of the new GNG/cycmotor X1-pro 3000w

With Gear version you will need a motor chainring instead of gear pulley. What type will give 60-80km/h: 11T, 22T with 20S battery and 36T sprocket 29" wheels? Cycmotor advised 12500 motor rpm with 20S battery. You mentioned gear ver. has a freewheel in right direction. In chain ver. motor should sp...

Re: Direct-Drive conversion of the new GNG/cycmotor X1-pro 3000w

If I have 5-6mm clearance from my caliper to spokes of rearwheel, will your adapter fit to my setup? Why do you want it without built-in freewheel (with X1 built-in freewheel) as was shown in post by ScooterMan101 » Dec 09 2018 8:03am? This chainwheel will be spinning all the time you ride.

Re: GNG X1-pro 3000w

Another reason of the similar torque values of X1 and BBSHD could be that BBSHD torque is not correct. I think 160 N-M for 1KW motor is overestimated for sure. In other words, it's 64kg of downforce on a 30.5cm lever. X1 should be more than twice powerfull against the stock BBSHD in side-by-side com...

Re: GNG X1-pro 3000w

As you say it should have a bit more peak torque but more than twice of current consumption. Does it mean X1-Pro is not as efficient as BBSHD which can output the same torque with 30amps of current? Or perhaps X1 peak torque achieved only at 3KW power consumption with very high rpm at cranks? With t...

Re: GNG X1-pro 3000w

So, with the same rpm at cranks as BBSHD it will have similar power level as well as torque?

Could anybody enlighten me how this motor set can have almost the same torque as stock BBSHD but to be more than twice powerful by perception, not only by watt numbers?

Re: How To, 50A BBSHD Controller Mod

Perhaps someone would be willing to make a schematic (some kind of reverse engineering) for controller pcb, than we will know for sure if everything else goes through the display and then to a voltage regulator on the main board. I would do it if I had the board. Fechter, have you tried your transis...

Re: How To, 50A BBSHD Controller Mod

We can't be sure for smd caps. 63V is a standard rating voltage for them, while 80V isn't. Smd transistors, diodes should be rated 90V or higher. All of the stuff on the pcb should receive full voltage potential unless there are components in the circuit set to maintain it at lower range. Btw, you c...

Re: How To, 50A BBSHD Controller Mod

That's great. I think the best solution here can be Onsemi FDP2D3N10C mosfet. It's 222A Id, 2.1mOhm Rds, and only 214W Pd.
Could anybody compare this moded controller with phase runner? What are pros and cons?
Also the capacitors should be 105-120 C rated, it will be hot inside the controller case.

Re: How To, 50A BBSHD Controller Mod

I would definitely change the NF75 to 100 V FETs because overvolting gives so much more power feel. As proposed, doing the display voltage hack just might help the PSU chip as well to accept higher voltage than 80 V anyway. Have you had a chance to try this out? I'm interested in 100V mod too.

Diy isn't the point here, but cheaper cost via diy. Amberwolf wrote Lebowski controller may not cost less, than why bother with it? Seems like there is no way to get such controller cheaper. Btw, electric motors as well so expensive. This is the main reason why not many people wish to shift from int...

Re: Compact Field Oriented Controller, ASI + Grin, limited run

I'm not familiar with this. But If you could give me a schematic, layout and other stuff required for diy I could try.
