@torqueboards sorry if anyone ask this already but for the Torqueboard direct drive, how long is the DD from axle to axle. I didn’t want to assume that it’s the same as your new CNC trucks.
BTW how long until you put the AT adapter on your site?
@Gee I think it’s about 330mm. Would be same as CNC Trucks. Maybe 1 month for AT Adapters they are in production now

@torqueboards On your site it said axle to axle length is 244mm…So 330 mm or 244mm?
- HANGER LENGTH - 220mm / 8.66"
- AXLE LENGTH - 25mm Axle Length + 12mm Shoulder Length + 11mm Threaded Axle = 49mm / 1.92"
- AXLE TO AXLE LENGTH - 244mm / 9.60"

@Gee 330mm is with 110mm wheels from end to end. That axle to axle length is actually wrong. It would be 318mm. Thanks for catching that.

What motor amps is everyone else using on these?
I’ve tried pushing my 90kv set up to 100 motor amps per motor and noticed some cogging under full throttle, I guess the stator is being saturated. I never had this kind of cogging under full load at 80A, might give 90A a try.

I have my 75Kv set to 70 motor amps. I had cogging at ≥ 60 amps in sensored FOC. Once I changed the “sensored to sensorless transition rpm” to 10000rpm I haven’t had an issue. Mine makes a cool noise too at sub 10 mph then it goes whisper quiet

My two most recent TB DD builds are coming back and they want belts. The motors are seizing either shortly after detection (as in by the time they get to the customer) or immediately after riding.
I think some more development or iteration needs to happen.

Seizing as in the motors are locked up completely?
more like a partial seizing where they are just really hard to turn, harder than the kind you get with shorting the phase leads, but not totally dead locked. I sent one set of motors back to Dexter for testing and to exchange them, but then the ones I had on hand to swap out for the customer also did the same thing, so that was two out of six that did it. I have one customer out riding around care free just killing it on his. And two others with issues. Can’t blame the whole batch but something is definitely up.

This doesn’t bode well

I don’t know your plans for the motors, but could open and clean the bearings of one of them? I’m wondering if electrostatic erosion is occurring, depending on the motor design you need one of the bearings to have a insulated coating to avoid closing the circuit and allowing a current to be induced

it’s interesting. this is the first time I’ve heard of these motors having issues like this. there was the one case where they would heat up like crazy. how many other people have had issues? Ivan really only speak for me and others that I’ve ridden with that have these motors and so far my only personal and observed experience has been flawless.

I only have four customs with them atm. Out of those 8 motors, 3 have seized in this weird way.
yes this is strange. let us know what D says, maybe he will chime in here.
He’s agreed to swap out my motors, and I gave him as much detail as possible. I think if there’s a defect, he will be able to find it and figure out a work around or something.

This sound like winding problem with making motor.
@torqueboards if you’re lurking, help us help you build better direct drives. The demand is there and I need them to work right so I can build boards faster.

Would be somewhat nice if you stop spam us with emails please.
Of course you will tell me to unsubscribe if I’m not happy, but getting 5 emails over this week for this DD drive isn’t really pleasant.
