Re: New "TSDZ2 Torque Sensor Central Motor"

~88kg. Guess around 95 with camelback and other equipment. I would think bottoming out 160mm suspension on the other bike is a lot more weight on the pedals. Im not jumping the fatbike, but it is a hardtail, so maybe the shockload is higher after all...? Shock load is what will start a crack at the...

Re: New "TSDZ2 Torque Sensor Central Motor"

Broke the spindle on my fatbike the other day. I was tuning in the pressure on the front fork, so I put a lot of weight on the pedals, and the drive side just snapped. Thumbs up for Ebird store for just shipping out a new one for free. Told me they were stronger now, but Im nor sure about this moto...

Re: New "TSDZ2 Torque Sensor Central Motor"

Little review off my TSDZ2 (48v motor 52V battery) With the OSF, thermal pads and temp sensor is a damn good motor (never used it on oem form :mrgreen: ) I have ridden some bosh and yamaha (entry level ones) and the TSDZ2 is in my opinion better and more powerfull (and with the osf way more flexibl...

Re: Measuring motor current profile

Has anyone tried to measure curent profile on motors with torque sensors in order to better understand the behaviour of the motor. What exactly are you trying to determine? It sounds like you are looking for information a dyno (dynamometer) would provide you. If so, there are simulators like http:/...

Measuring motor current profile

Has anyone tried to measure curent profile on motors with torque sensors in order to better understand the behaviour of the motor. Hard to make any sense of fluctuating numbers on watt meters like WattsUp and others. Tried to use current probe or shunt with an oscilloscope but it shows some rounded ...

Re: New "TSDZ2 Torque Sensor Central Motor"

I'm running 36V TSDZ2 with VLCD5 OSF and 48V battery. In the past two and a half months I biked over 2000km. So far so good. I just received spare blue gear just in case I need to replace it soon. One odd thing I noticed is that when pedalling quickly uphill it seems like motor "slips" (can't reall...

Re: New "TSDZ2 Torque Sensor Central Motor"

Very useful information indeed. This might be helpful also for displays that show condensation on the inside. Changing desiccant every 12 months would be too much to ask for. It wouldn't on hobby projects but it is impossible to do that on the "real" ebikes of my shop's clients though. Might be eas...

Re: Watt Meters

The Wattmeter needs to placed in series between the batt. and the controller, not paralleled. I have had about every kind of instrumentation from a CA on down and these days I just use a Voltmeter, it's all I need w/ LiPoly, as it's discharge rate is very linear..

Re: New "TSDZ2 Torque Sensor Central Motor"

Although it may seem that way, alas its not quite so, often I find that it feels like the motor is not putting in much power until with the OSF software you can display the motor power in Watts, very often with what feels like minimum motor input on long climbs you have already reached the max moto...

Re: New "TSDZ2 Torque Sensor Central Motor"

I have had a problem with TSDZ2 for months. At first he noticed that the power had decreased, he was pushing less and less. Later it began to happen that from time to time it would go off, especially after a while pedaling and more likely on a steep hill. To try to find the problem I have flashed t...

I have a frightening problem with my TSDZ2. As soon as I connect the battery, the controller starts smoking and sparking. It wasn't always this way. I opened up the motor to replace the blue gear with a brass one, but I had problems when I put it back together and tested it out. First I noticed I w...

Re: New "TSDZ2 Torque Sensor Central Motor"

How can this brake the sprag clutch? Some who are using 2mm spacers between the main gear and the spider as a requirement to mount two chain rings might expect the failure of the sprag clutch then. Well I can't be sure if it was because of the gap or if the clutch was faulty, but soon after I chang...

Re: New "TSDZ2 Torque Sensor Central Motor"

But beware, at least my spider was not a perfect fit. I had some play in the axle which is difficult to eliminate completely, as discussed before in this thread. Thus the spider rubbed against the outer plastic cover of the main gear, and both the spider and the edge of the cover are worn out. I no...

Re: New "TSDZ2 Torque Sensor Central Motor"

To: Darkerside. If the wobble in the chainring turns out to be in the sprag clutch I wouldn't worry about it becasue when the sprag clutch locks under load it will center iself. If it's in the fit of the bearing bore there are Loctite type fluids for loose fit bearings that can be used for that. I'...

My motor did really bite into the frame at the chain stays :( I’m worried this will cause a rust issue down the line since this frame is cromoly. What do you guys think?

Re: New

...... What about the right side? I think allowing play on the right side only might put more stress on the axle. Again on the Italian Jobike forum someone has put a thin sheet of metal inside there . For that purpose you can use the metal of a feeler gauge. Could try, but the whole construction ki...

When you remove the snap rings and main gear from the drive side, you can push the axle out of the left side and removing the bea...
