Re: what's that sound?

Casainho, Do you have brake sensors instaled? Yes, I do have now. My very first time, I didn't and the blue gear wore just after 20 kms, after I did a few brakes with motor at max power settings of original firmware. The blue gear did damage to me only on that situation and after some times when my...

Re: New

Consider replacing the plastic with the brass gear, apparently not too noisy. And personally, I'd stick to a 13A ceiling, even 12A better. Or go to BBS02 (better than BBSHD?) I don't mind replacing the blue gear. There needs to be a "weakest link" that's easy replaceable. I just wouldn't have expec...

Re: what's that sound?

Also, you are using the OpenSource firmware so there should be no warranty anymore. Also, are you sure the 14 Amps second increase ramp is a safe value? Did you tested it for how long? I wouldn't have expected and warranty at all. Sending the motor to some other country, and waiting several weeks t...

Re: New

Stripping the gear would require abuse by definition. What's the max phase amps used? Unless they had a bad batch of Delrin or something. It's set to 16A battery @14s. Brake sensor & temp sensor installed, and never got over 80, but problem began at 50C already, so it shouldn't be a heat issue. The...

Re: what's that sound?

How do you know it's my fault? And NO. I got brake sensors, and no jammed chain at all. All running fine. Well, if is the blue gear damage teeth, then probably you did / happened something wrong with the mechanical part of your bicycle. Check the wiki FAQ. Even if it's the blue gear, and i don't do...

Re: what's that sound?

Had my maiden voyage today, first time riding more than a few meters in the driveway. All went fine, but after around 20min a strange sound started inside the motor. When I had a similar sound it was grit in the teeth of the main drive cog (the one with the sprag clutch bearing in it). To check, re...

No, do not translate!! It should be the contrary, everyone should learn the simplified English. I agree.

Re: New "TSDZ2 Torque Sensor Central Motor"

Totally depends on your bike and weight. With a fatbike and bad gearing it sounds reasonable.
What's your cadence in highest gear? Normally, I'd say 40km/h needs around 1000W, and this kit is able to deliver 500W sustained and ~700W-800W (battery) peak.

Re: New "TSDZ2 Torque Sensor Central Motor"

I use a 16 tooth and a 23 tooth sprocket at the same time on any Alfine & Nexus hubs. Machined down and welded together with a derailleur. It allows me to have the best of both worlds, speed on the flats and downhill and great climbing ability on the uphill. https://youtu.be/G6kQvM4Or3U https://you...

Re: 90rpm cadence limit

I assume, and you wrote it, CPU seems limited with this controller, but I think field wakening is the only way to go to get support at higher cadence. 90 is a good rpm for long time pedaling, but as mentioned it can be much higher for shorter periods. The other advantage is, that you can gear the b...

Re: 90rpm cadence limit

I need to write about this. I consider the firmware is mostly finished by now and so it is a good time to write about all this. cadence 90 RPM = 512 motor ERPS / 4000 RPM (motor RPM nominal value) 1. the motor itself, should achieve the 512 motor ERPS (cadence 90 RPM) at 48V battery voltage but wit...

90rpm cadence limit

Could someone please give me the info about higher cadence software? I read it once but can't find it anymore. And what's the reason to stop motor power at 90rpm? That's too low for my finding. If you do a fast downhill you can pedal much faster, and same goes for very slow uphill in lowest gear. Is...

Re: New "TSDZ2 Torque Sensor Central Motor"

I am running stock 52v firmware on the motor and euronau firmware on the 850c, and it also does the same. I usually turn off things by flipping off the switch on my battery, but I will start using the actual power off button on the 850c first and see if that resolves the issue Now that you mention ...

Re: New "TSDZ2 Torque Sensor Central Motor"

That happens also on may displays, maybe it is an issue on the firmware... That's good to know. If it's software I'm sure you will solve it. Better than having to deal with a hardware defect that is not clearly to be identified. It's no important feature at all, but if there is a clock shown (which...

Sure. You're right. Haven't thought about that. But different crank lenght means different power. That's also the reason i asked for a higher cadence version.

Re: Klein Mantra rebuild / TSDZ2

It rolls. I may swap the 52T front ring for the original 42T one, as it's geared too high to my feeling. 16T in the back. The Alfine 11 is super nix. Adds some drag and is NOT as easy to pedal as a "regular geared" setup, but being able to shift gears at a stand still and having an almost perfect st...

Re: New "TSDZ2 Torque Sensor Central Motor"

I finished my bike today. Have the Alfine 11 installed, and a 52T front ring, 20T in the back. But this is to high geared. I will revert to the original 42T next and try that. Also have 16T, 18T and 23T for the back to try and get the optimal setup.

No need for more current. The bleeding resistors are all that need to run current through the wires/connectors. And unfortunately they can't run more than that anyway.
