The BOSS welder is super simple. The first post on the thread about the welder has all the settings you may need for whatever type of strip you're welding in your pack. I had never spot welded a pack before this, and by my 3rd weld I was comfortable with it (don't drink a pot of coffee before you start). All you need to power it is a good 3s high-C battery. It's literally press down on the area and wait for the beep, then move to the next spot. Honestly, soldering-in the BMS and discharge wires was more nerve-wracking than welding the strips in.
Yeah for sure! I know several people here have a few different ways to open these motors up, but it'll definitely be interesting to see what I get as tools/instructions for opening this motor.
I don't. BMSBattery sent it to me as a courtesy with the replacement motor shell since the one I got with my motor had the spoke holes drilled incorrectly. I haven't seen the tool listed on their website.
My first thought was that the halls didn't match up, but I thought the phaserunner could figure out what the wiring order was automagicly.eCue wrote: ↑Feb 16 2018 10:32amIts common for hall sensors wires to be the wrong pin holes at the connector ends.
I switched two wires of three (not positive /negative) a few times until the motor synced and ran smooth. In my case I had to switch phase wires around as well. White was the speed sensor for some its the self learn
Is that wrong? If so I can get back in the wiring and figure out what's what.Next up, you will launch the spinning motor test, which will cause the motor to rotate at about half speed for 15 seconds. During this spinning test, the controller will determine the exact kV winding constant for the hub and also the pinout and timing advance of the hall sensors if they are present.
Yeah, I reset the settings in the app before I disconnected from the controller last night. I agree with you and will wait a bit in the hopes I can get some more info from someone. I think I'll also try loading the Phaserunner Suite app on the PC to see if that's any better than the Mac version. Thanks for your help eCue, I appreciate it.eCue wrote: ↑Feb 16 2018 11:49amI only have experience with my hub and controller> Try resetting and running threw the cycle from the beginning. Hopefully someone chimes in this morning with phase runner knowledge so you can get this up and running. I would wait for that advice befor switching wires
What's really funny, if you've read my previous post, is that this ratio make the number of pole pairs 65, just like was in the Phaserunner thread. LOL I guess whatever was causing my trouble before is either related to the software, or the faulty hall wires. We'll see soon.I popped the side cover off of my 260 RPM Q100H and counted the gear teeth. I couldn't get the planet gear carrier screws loose. I don't have an impact driver, and when I used a screwdriver bit in a socket wrench it felt like the screw head was going to strip before I could break it loose, so I couldn't count the sun gear. I was able to count the 1st and 2nd stage planet gears along with the ring gear though. Interestingly, they are the same as Papa's 328 RPM motor.
Sun: (assumed) 15 tooth
1st stage planet: 36 tooth
2nd stage planet: 23 tooth
Ring: 78 tooth
Sun to 1st stage planet ratio: 36÷15 = 2.4 (not needed for final ratio calculation)
1st stage planet to 2nd stage planet: 23÷36 = 0.64 (overdrive, need to multiply sun tooth count by this)
Small planet to ring gear: 78÷23 = 3.39 (not needed for final ratio calculation)
Since the planet carrier is fixed (it's part of the axle) the formula to calculate the ratio is simply ring÷sun, but since this is a multi-stage planetary, you need to multiply the sun gear by the overdrive ratio.
Sun times overdrive: 15x0.64 = 9.6 tooth
Overdriven sun to ring gear: 78÷9.6 = 8.125
So the final ratio of the reduction is 8.125:1.
Here's where things get really strange. What this tells me is that either:
This is going to get even more weird. On BMSbattery's website, the Q100H is only available as 201 RPM, or 260 RPM and the Q100 is only available as 201 RPM or 328 RPM. The Q100H says it has a 12.1:1 reduction ratio, and the Q100 says it has an 8.2:1 reduction ratio. Soooo, what the heck is going on here? How is Papa's motor 328 RPM if it's a Q100H, and how is my supposed 260 RPM motor geared the same as his? And how are both of these motors only 8.2:1 when the Q100H is supposed to be 12.1:1?
- The wheel RPM (201 vs 260 vs 328) is determined by the motor winding and not by the gear ratio, or
- I received a 328 RPM motor, even though I ordered a 260 RPM
Thanks Amberwolf, I think I found the issue (hopefully), but I'll keep that advice for if I am mistaken.amberwolf wrote: ↑Feb 17 2018 2:20pmThere might also be noise in the hall wires induced by the phase wires. Sometimes adding a small capacitor (0.1uf or less) in parallel with each one to ground cna help with that. Or adding one from teh hall power to hall ground, if the noise is in hte power line.
Anotehr thread recently reproted diodes in series with the hall wires fixed an issue with a different controller and motor. I don't recall the thread title, but searching for
should find it.
Hey RollerBoy, I totally missed your question—sorry about that! I'm in EAV and work over near midtown, my company's office is in Ponce City Market.
