Re: Lebowski's motor controller IC, schematic & setup, new v2.A1

I should say as well that if you want Somaloy, I can get some. You won't like the price.

Somaloy machines pretty much exactly the same as the micrometals stuff, though it may be sliiiightly harder.

Re: Neumotor 8057/75 middrive project, belt drive, adding halls, 10kW+

The holder is made of aluminum so there will be eddy currents, but i hardly think that this small surface area behind the halls would heat up so much to toast them. Thanks, they definitely weren't significantly heating. I really don't know. Now, I'm not running resistors, but I never have on ss411a...

Re: Neumotor 8057/75 middrive project, belt drive, adding halls, 10kW+

Ah, makes sense. Manual version of setting a digital encoder or resolver. This solution works quite well...when the halls are functioning. Twice now, I've had the bike running well, then come back and the halls were all shot. Not sure why. They definitely aren't touching anything and there's no phys...

NIce.. I love high powered brushed motor :bigthumb: One question: Why don't you extend the motor plate so that it can attach to the lower engine mount?

No real need! Look at where the force goes and that mount doesn't really do anything.

The Quickest and Dirtiest of Builds - Brushed KX65

Built this guy in 30ish hours after my other race bike had some major issues and wasn't going to be feasible for the season opener. Nothing special as you all can tell. PMG132, Kelly 600A controller, and HK lipos. Went out, had no issues, and it was one of, if not the, quickest bikes out there. I'd ...

Re: Neumotor 8057/75 middrive project, belt drive, adding halls, 10kW+

Made yet another revision, this time to allow building of the hall-sensor module off of the motor, and for much better wire routing. This is after tumbling it to deburr in our 4-foot diameter vibratory tumbler with polyester tetrahedrons. Edit: I can't change the orientation of the image for some re...

Re: Neumotor 8057/75 middrive project, belt drive, adding halls, 10kW+

I realized it was somewhat difficult to tune the hall position due to some dumb dimensioning. I reworked the part today for more adjustment range (On gap? Middle of tooth? Somewhere in-between?) and better centering. Don't quite get the relationship between initial hall position and termination yet,...

Re: Neumotor 8057/75 middrive project, belt drive, adding halls, 10kW+

It is tested and switching well. The slots are slightly longer than the sensors to allow moving them across the thickness, but I didn't end up needing it. Controller testing will happen tomorrow or Tuesday and we'll see for sure. I'll probably throw the scope on it, too.

Re: Lebowski's motor controller IC, schematic & setup, new v2.A1

Kiwi and I are working on a board for the 08 Civic IMA inverter right now. Hoping to have something functional in the next few weeks. It will involve chopping the existing board to leave the gate driver power supply and grafting on a Lebowski chip. A full drop in solution may come later pending init...

Re: APL's DIY axial-flux motor

8-32's are actually pretty available! Little spendy for the size, but I think still reasonable for the project. Standoffs, however, I'm not sure. Don't think I've ever seen that size of ti standoff.

Might be a dumb question, but would Ti screws help significantly with the eddy current issue?

Re: APL's DIY axial-flux motor

Looks good! Agreed with CNC probably being the best. Laser won't do it well and waterjet will likely delaminate it. Perfect part for a router with a vacuum table.

Re: Razor RSF 650 QS 138 10kw beast build

Been there, done that. Sorry to say messing with the rsf isn't worth it. I used an my1020 brushless setup on 64V nominal and 200A. It was a blast, but the suspension is sooo, so bad. The front brake bracket will bend and you'll smoke pads in no time. You really need scooter-style brakes for it, then...
