The motor drive is here!

I ordered a motor drive last week from the internet. In the past, these were the kind of things you would have the purchasing representative from you company call the regional sales rep about, a price would be quoted, and a lot of paperwork generated. Now, there are a couple of places to get industrial equipment on line. I bought this one from factorymation.com, as they had brands that I had heard of before. Whatever that's worth.

The drive weighs about 30 kg.

The business end: This is where the cables from the batteries and to the motor will run. The fans dissipate waste heat. The unit is about 90% efficient, but that's still nearly 2kW of waste heat at full power.
