The TSM-A5, a Direct Drive Hub Motor with Integrated Torque Sensor
HTML-код
- Опубликовано: 6 сен 2024
- In this Video Robbie introduces a new motor from TDCM that we are now stocking here at Grin. This is the first hub motor that we are carrying which has a built-in torque sensing freehub so that you can have torque control without the need to install a separate bottom bracket torque sensor. Although a few motors like this have existed on the market (BionX, Falco, and others) they are still surprisingly rare in aftermarket kits.
Additional details are available from the product info page:

With a limited quantity available to purchase as part of a kit on our RTR kits page:

Love that quick release.
Very good, I hope that integrated torque arms and quick release hub motors become the norm in the industry. I wonder if the GMAC will be updated to have a quick release, or have this new integrated torque sensor? Regardless, keep up the brilliant work, Can't wait to see what's next!
A GMAC with QR and integrated torque sensor, heck yeah. It would be on my Christmas list.
Glad you like this and for sure we'd like to see move more motors in this direction. The challenge doing QR on a GMAC is that the cable exits in a diagonal slot that passes right through the center of the axle, so it requires quite a substantial redesign of the MAC motor core to allow a hollow channel all the way through without interfering with the cable (ie new shell castings for a larger ball axle bearing diameter etc.) Adding the innotorq freehub body is a bit similar, doable in principle but requires all new mechanicals so a lot of up front tooling. It's on our wish list too.
Whats with the anoying background music guys. Totally distracting and hard to hear.
Nice technology.
Wow, that is really cool. I am late to the party and looking for my first ebike converion. This solves or improves so many little things and I want backpedal regen but now with quick clamp and a cassette mount too. Stoked to see if I can make this work.
It’s never too late to get, or DIY, an E-bike in life.
I strongly suggest you consider the option of a front wheel motor - using the All Axle motor. It is the cycle analyst that determines the Regen and torque response not the motor or the controller and separate torque sensors are available from Grin to send signals to the CA and then on to the motor - back or front - to do all sorts of magic. The front motor has the advantage of simpler removal is case of puncture - and can be used to balance a battery located in the rear of the bike - in my case tucked inside a bag under my seat. All Axle is 4kg v this new one 6.xkg added to the rear.
Very nice !
I wish your website was a put together as your RUclips channel
I really wish you guys would come out with a mid-drive motor to compete with BaFang.
But we're on team Hub Motor! ( ebikes.ca/learn/why-hub-motors-are-awesome.html )
@@GrinTechnologies What's the real reason?
Yuck. Lol. I'm a hub motor guy.
Cool hub. A little hard to hear the explanation of the technical details though.
Would like the industry creating options for thru axles
Thru-axle please :) Looks great otherwise. I know this seams trivial, but from an aesthetics perspective, it might be nice to offer different length cables from the motor or allow a custom ask in the order form. I like the connector but it is bulky and an eye sore compared to many pre-built bikes.
Love seeing an engineer owned company growing and still innovating.
I have question: is it possible to us the torque sensor to give the speed for additional motors in parallel. This way it would be possible to use the signal for a all wheel drive or even a powered trailer.
Interesting question, and the answer is that with a CA3 controlling the system you definitely can. The wiring from the controller to the CA with the torque signal is totally independent of the regular CA-WP plug, so it is no different from a wiring perspective than a bb torque sensor.
Just wonderful it is 😁
1000--2700$ price + accessories = way to much for this Dutchman. Looks like a nice motor for the rest.
Nice work can't wait to try it out 😎
Thought I want a bafang bbshd as my first ebike motor but those hub ones look kinda neat!
where you left the clyte 4040 motor it went missing.
How much torque does that make? I live in an extremely hilly area and anything 70nm or less is subpar.
With a high current motor controller it can do 70Nm for short times no problem, but in any sustained duration at those torque levels would cause the motor to overheat and go into thermal rollback which will then reduce the torque output.
Can you take advantage of either the torque sensing or regen breaking without the cycle analyst?
Not in the current implementation of the kit, but in a future update this will be possible.
What would be my options for a gear hub 1000w motor replacement for a fat ebike?
@@GrinTechnologies how are we coming along on that?=
My dream come true
Nice motor, i'm waiting for the fast winding version because the low pole count of the motor would make it the most ideal motor for a recumbent/semi-recumbent with 20" wheels.
in my dreams it would also have a QR as a rear wheel flat on my recumbent trike is a pita.
@@linberl I can see that. I chose to run 16" motorcycle tires ( 20" in bike size ) for that reason, lol..
@@linberl I can see that, i run motorcycle tires in the back of my recumbents for that reason, lol.
@@neptronix do you use a tube, or how does the seal work with motorcycle tyres?
@@DeUser1337 It's quite simple. You need a wider than average rim ( ~32mm ) to seat the tire and if you take 4 inches off the bike size, you've got the motorcycle size.
Example: 20" bike rim fits a 16" tire.
Also you can use whatever tube you want.
The only asterisk is that motorcycle tires are very hard to fit!
Does it work with another display or is the cycle analyst a requirement. Sorry to say, but it looks like something from the 80's. I want a small and sleek display on my bike.
This is just a motor. Controllers and displays are totally separate unrelated items. You can definitely run it with any other motor controller that can respond natively and safely to a voltage torque signal as long as your have the know how to configure that.
How many watts is the motor?
Watts is a function of RPM and the time duration that you need it to run before overheating. So if you give us those two parameters, we can tell you the corresponding wattage.

It's a shame that this is incompatible with the new phaserunner, since I think this is probably my ideal hub motor. Will probably end up getting a rh212 instead for this reason. Maybe an adapter cable or something could solve that?
You can in fact power the motor from a Phaserunner_L10 just fine, but you won't have valid torque or motor temperature signals. If you wanted that, you can cut and splice your own wiring to bring the torque and temp signals up to the CA without too much difficulty. It won't look pretty but it will do the trick.
Nice one
I need one of these for
El Diablo
My freak chopper
>_< i need a fast wind version of this for the 20" wheels on my tandem
Unfortunately we only got the one option available, but with a 52v battery and the use of controller field weakening you can still get quite a good speed (upwards of 30mph) in a 20 inch wheel
Having a quick release is a good way to get your stuff ripped off where I live. They'll even take the skewer if that's all they can get. Tweeker, go figure. Please, please have the option of using regular nuts that can be secured.
It'll work fine with any of the anti-theft bicycle skewers available too, and those are a harder for a rando to remove than regular nut which just requires a common wrench or pliers.
It would be very interesting to know how much regen can make a difference. If it's enough of a difference, a user could buy a smaller battery to cover same range as without regen. Lower the cost and weight of the bike. Please follow up with test results.
Alen The biggest reason for Regen is cost saving from extending brake pads and rotors. Battery recharging is more a by-product of this saving but can be useful in some situations where the terrain suits regen - and not all terrain does. Heavy or heavily laden bikes benefit most from regen. Grin / Justin did a video about this recently that is full of interesting facts.
ruclips.net/video/gYCj4asp9pE/видео.html specifically!
Do you need an external speed sensor, or is the speed signal being combined with the temp sensor like in the baserunner Z9?
It's actually coming from the standard motor hall sensors, as is normally the case with direct drive motors like this. A separate speed signal would be quite redundant.
@@GrinTechnologies oh! of course! Thanks!
Very interesting
What ate your plans for your Lego-batteries, will we be seeing phosphate type batteries will greater Amp hours available in the near future?
@@vikferreira2137 what ? youre talking to wrong person i think.
Do you have a kit to fit on a Tandem adding hub to rear wheel with a standard bolt on axle? Please no quick release.
Many tandem bikes have a 145mm rather than 135mm rear dropout, so usually if people insist on a rear motor they would put a few washers on the axle to extend the length for a better fit. See ebikes.ca/learn/bike-compatibility.html#TandemBikes(100/145). The RH212, eZee, and SX2 all all rear bolt on motors that work great on tandem bikes with some spacers, and any front hub motor works fantastic too.
You mentioned 3.2 as if it is out of beta? Any ETA for non beta 3.2
Good question. Beta 3.2b3 has proven to be quite stable with lots of users over the past 6 months so we may just make this release into the official 3.2, and save other minor feature additions for a 3.21 release.
@@GrinTechnologies Will the release version have a fix for the backpedal regen / cruise control issue that's present in 3.2b3? Can't imagine it's a common issue to run into, but I know I'm not the only one looking forward to a fix. I've been running b3 almost as long as it's been available, and it's been great aside from that one issue.
Yes it will!
Need through axle!!!
not shure what the capabilities offered by torque sensing is but cool
In short, torque sensing means that your ebike can tell how hard you're pushing the pedals. This allows the tiny computer running your ebike to do things like automatically vary the level of electric assistance you get based on how much force you're putting into the pedals.
I have BB torque sensor with All Axle and it is a game changer from throttle control. You pick the multiplier ratio on CA and the torque sensor provides that amount of power according to how hard you are pedalling - the resulting smooth assistance is truely wonderful. BTW my All Axle is on the front wheel - and works very well.
Love a new Grin Tech video, but that "music" could have been penned by Satan himself. Bring back the Be-bop intro.
Guys, whats with the background music? sheesh, turn it off please!
