Brushed Controller from Salvage 3-Phase Inverter?

I'm in need of a higher voltage DC controller (120V nominal, ish) and am on a tight budget. Anyone ever done a brain like Lebowski's, but for DC drive? I've seen Paul's DC version of his big inverter and would imagine I could do something similar with an IMA inverter. Same long leads for better curr...

WTB - 120V+ Brushed Controller

I'm looking for a 120V Brushed controller. Anyone have one laying around? Only need 200A battery, 100Aish continuous.

Re: GM BAS Gen1/2007-2009: Worthy to mess with?

If you have the voltage to run it to its potential, the Hyundai HSG is a far better option than either BAS/eAssist motor. There are several threads on it now.

Re: Lebowski SMD brain running a zombified Honda IMA Inverter: *a HOW-TO guide*

I'm excited to see this! Kiwi and I keep saying "we" are working on it because my company is funding his work, but make no mistake, he is the electronics brain here. I just buy the stuff, tear it apart, and send it his way to be modified and iterated-on!

Re: Mid-drive IPM motor options?

If you're worried about size, then MG1 is way too big. Kiwi and I are working on a Hyundai HSG project right now. Stock, the housing is about the size of a normal truck alternator, which is too big for my application. I'm building a housing for it now, and will report back after all this corona crap...

Re: Roman Kostrygin - Sur-Ron 16kw outrunner

I have no dog in this fight, but...In the end, you sold him a motor that you hadn't fully qualified and tested. While he seemed to understand the risk, that's still bad form. As evidenced by the destruction, 10krpm is a lot of energy with that mass and diameter.

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.

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...
