i have not found a sprocket to fit it yet, i do how ever own a metal lathe to make an adapter to fit a sprocket. i have a 5hp diesel engine. was suppose to be a 10hp but the ebay seller said they sent the wrong one. so im going to try this 5hp

Hello all,
I am considering one of the HEV/HSG motors for a motorcycle build, but I am having troubles finding any for sale.
I must be missing the key words or special search methods... Are there any live references for units for sale?

What are you going to drive it with?

I’ve been looking for a sprocket that would fit onto the shaft, no luck so far as it’s 22mm diameter shaft with a 4mm width woodruff notch. the standard for a 22mm shaft is a 6mm width notch.

nice. But what did you do for the hsg shaft? Just turn down and weld a sprocket on the original pulley?

I haven’t found a keyed pully or hub with the same diameter and keyway

i cut the third to last vbelt pulley off, that left the flat metal on the pulley that i then welded the sprocket onto, of course centering the sprocket onto the pulley before welding was tricky, out of all things i used electrical tape to fill the gap between the shaft and sprocket, that then allowed me to spot weld the sprocket onto the pulley.

Hi everyone, I have a Nissan ENV200 van and want to make a range extender generator for it. What is the continous power output of the HSG when used as a generator? The kia niro website says 8Kw but doesn't specify whether that's as a motor or generator. I need 5KW minimum. I will use a vesc based board dropped into a BMW I3 REME inverter to control it, and development of this board is almost done.

Hi Shaun, it will be the same power as a motor or a generator, does not matter.
Interesting project, I also got a small generator for home power, was going to use lebowski not VESC but decided to use a solar GTI instead.

I use Honda ima + brain v3 OI inverters very widely. but I have not yet been able to find a point at which the native inverter board would report the voltage of a high-voltage battery.
Could you help me with this?

I use an isolated amp taking bus voltage off one of the IGBT's . There is non-isolated feedback noted in the original reverse engineering document but the transfer function is different for the left most feedback point compared to the right two. If you take a look under the driver board you can see two distinctly different feedback networks. The transfer function noted in the original doc applies only to the right hand two pickup points.

Take a look at what forum member Mouse discovered: viewtopic.php?t=1495
If you take that path you would need to convert back to an analog value unless you can pass that parameter over CAN to the OI brain.

Picked up one of these for a project and threw together a rough CAD model. Just done using calipers in front of the CAD computer, not based on a laserscan or anything so double check the measurements before you use it.

Hello, I would like to document part numbers for these, as it makes searching on eBay much easier.

I have found part # 3739003900, can anyone confirm that this model number is what this thread is about?
