Like new, never put in a vehicle.
Recently tested on a 1PV5138 motor at 380 volts. It works fine.
Other than those small tests, it has never been used.

Hi,
How do you control the inverter? Do you have a GEVCU unit or similar?
Is the inverter programmed ?
I am interested for driving a similar motor, a 1pv5138 .

It's funny you mention the 1PV5138, because that's actually the motor I was using to test on with this inverter.
I used the GEVCU from evtv to drive it. It's a bit on the pricy side, but if you just have an Arduino mega with a CAN-bus shield, you can do everything you need (and the evtv code is public and open source).
It is programmed as the 'watercooled' version and works just fine with the 1PV5138. I even have some specs from Siemens on that particular motor if you want to mess around in CCShell to get optimal values.

I believe under road conditions this inverter will work fine. I switched to a different one because I'm building a rock crawler which will be operating at very low rpm (meaning very low efficiency, maybe 60%) and I wanted to be sure I could cool that amount of heat. I'm not too knowledgeable on the topic, but I figured 'better safe than sorry'. Though my gut says, with proper air cooling it would probably be fine (especially because that inverter has thermal throttling built in)

I can sell it with the GEVCU for an extra $600.
However, if price is an issue, I would recommend just flashing the GEVCU firmware onto an arduino mega with a CAN bus shield (same thing).
As with everyone that buys a DMOC645, you need to build a cable from the GEVCU to the DMOC645. I can provide documents for these pinouts and the correct hookups.

I could do this for you. However, I would charge my time to you, that would be around an extra $300.
But it really is pretty easy to just do it yourself. I could give you tips.

I recently bought this 50Hp marathon motor to use in a 1/2 ton pickup I want to convert. I am thinking that the controller you have here for sale would make sense for this.
Am I correct?

Can you sell the motor too?
I cannot, I actually have 2 dmoc645s and only 1 motor. I'm using one set in my conversion, but I have seen a few posts here on other compatible motors for sale.

I'm not sure if this will work. I've seen the Dmoc645 used with a variety of different motors, but I would not be able to make any promises.
