Paul and Sabrina's Cheap 3 Phase Inverter (AC Controller) with Field Oriented Control

[HaroldinCR]

It's difficult to find technical info, at least for me. What info I posted so far comes from that video in this latest part of the thread, and, from another site online. I wondered about that RPM figure myself. Maybe I can find that article solely for a link here.

My contact in Spain has done tests with Curtis controllers. He feeds me info, and I try to help with what I find. I will ask him if I can put out the info online.

I shipped a Ford Cmax battery down here that has a controller/inverter in it, and, a Hyundai same deal. I will see if I can get them and open them up. My buddy has no use for them. Might be useful parts if nothing else.

I wasn't too concerned about the RPMs, as that can be compensated with pulley sizes. And with ruggedized and cooled electrical circuits you can lug right down to 0rpm.

My intent is to visit the local Buick dealer. They won't know anything but maybe there will be an example on the lot.

I just found out that we have possibly 2 Ford C-max controllers that I thought had been discarded and was given the Hyundai controller my buddy has, besides the Honda controller I had recently bought.

Should have enough parts at least, to make 1 good controller, maybe more.

Do you have an example of the motor/generator?

I just stopped by a Buick dealer and they let me look under the hood of a LaCrosse. The unit appears to be 8" in diameter and 8" overall. There was a lot of paraphernalia in the way, but it looks like the cooling and electrical connections are on the rear face; which means I couldn't just scab a stock VW cooling fan onto it.

The encoder/resolver is on the back end of the altermotor. There is no room for a fan.

Rig up a belt drive fan off the front shaft/pulley. Might need a jackshaft to do it.

Oh. VW. Forgot how they work. Fan on generator. Let me check around how others do it.

edit--Ummm, why do you need air cooling if you change out the engine for an altermotor ?? Cabin heating, maybe ?

I've been looking around.

The starter/generator is liquid cooled and has its own radiator and electric pump. The small radiator is mounted behind the engine coolant radiator near the top. The pump is operated with a relay that controls the power side of the pump circuit. It’s a simple on/off circuit, so the pump has only one speed. The coolant temperature sensor is a familiar negative-temperature-coefficient (NTC) thermistor connected to the control module’s 5-volt reference signal, but it’s built into the starter/generator and cannot be replaced.

Potential gotcha in italics.

If it it center-mounted like a Porsche alternator, there might be room to run a jackshaft past to the stock fan. Else there is the Type III crank-mounted fan.

If that long junction box can lay flat face down against the top of the case it would make a tidy install and route the wiring forward without impeding the cooling.

How are the motorcycle conversions going? I was reminded when I saw this on JACG:

That cutaway photo is the early model Gen 1. It has small magnets jammed between the rotor claws and is very under powered for it's designated use. You trying to build an E-assist system ?

You want the Gen 2 like in the video you posted.
Later today I will start a new thread with actual testing info sent to me from Spain.

Hopefully we can get the info from this thread transferred or copied to the new thread.

I'm up to my eyeballs in projects and hampered by the rainy season just getting started. Have not even ridden my home built moto this year or worked on the reverse trike.

We're just coming out of our too-cold-to-spray-paint season.

If your source in Spain can provide specifics, how about the dimensions — overall and the mounting points. Then I could mock up something and fit it to a spare engine I have on the bench.

Seems that motor is putting out roughly 23hp and 5 ft/lb torque according to the difference from year to year, does that sound about right?
Buick’s 37mpg 2012 LaCrosses with eAssist Priced at $30,820, New V6 with 303HP also Available

Nevermind, wiki has the answer!
At the LA Auto Show, on November 15, 2010, General Motors announced that it would be releasing an all-new version of the BAS system available in the 2012 Buick LaCrosse.[8] While still a Belted Alternator Starter system, the system is named eAssist and includes a larger more powerful Hitachi-supplied[citation needed] 115 Volt Lithium Ion battery and a 15 kW (20 hp) motor-generator that delivers 79 lb·ft (107 N·m) of torque.

Are these sold in america?! If so, seems like a great way to either hybrid your gasser or turn a motorcycle/scooter or hella fast bicycle!

There's one on the lot downtown; and I agree (except the bicycle part).
