Hi Nathan 219,
Thanks for your reply. It is encouraging to know another DIY fellow has his project`s wheels on the road. My LCX9000 came in yesterday, with the crate in perfect shape, and most certainly never been opened. Lying on top of the paper stack inside was a reassuring factory check off sheet showing the testing of all of the systems. The crate was itself a work of art, smelling like exotic pine forest and so pretty that I am trying to find a place to keep it, just to look at it. So now on to weighty business.
Somewhere I read that this Eaton drive passed some stringent testing for vibration and shock. With all the miles of transport it has seen so far, lying on it`s back on a skid, a high tolerance for vibration is certainly a high positive. And yet I know this drive is not offered by the company for use in a mobile setting.
I decided to try it for a mobile after seeing a Youtube vid of a fellow in-I believe-the Chek republic who put an industrial drive from Danfoss on a Subaru. So he certainly bypassed the converter front end of that drive. Then I learned that ABB has a three phase drive fed from a DC bus, called the ___M1. While considering that inverter drive, I found a Eaton C-H that inputs DC to an AC motor, and I read where this drive also, like the ABB operates PM Synchronous motors as well.
The Ebay
negotiations went well, along with a helpful seller, here it is, almost alarmingly small (not a surprise), 121#, and water cooled. I am hoping there are no deal breakers on using this drive, and so my first concern is-with other mobile drives with fairly high power, what is their process for `grounding` the drive. Could this be as simple as a routine low voltage ground in an ice car? It seems as though they are asking for more. However I am aware of the whallop this drive will be controlling, and would like to understand how other systems handle this, such as Tesla.
And this is my starting point. I will also need to consider how to set up regenerative braking. My drive came without a brake chopper circuit, although one was offered as an option. I will need to study how that option looks in place, and whether the chopper, if used with regen., may be a rather simple add on, or a complex system.
I know that a orderly mind would have resolved all these problem before spending a bunch on equipment that could have some challenges. But this project is a balancing act between not spending ourselves into poverty and still trying to collect and build this system as having some chance to actually work. Is anyone else puting a robust PM synchronous motor into anything mobile? I hope to be able to see what 850Nm is like. Best wishes to all. Morf
