100hp constant torque rated
125hp variable torque
150 % of rated current allowed for 1 minute
180 % of rated current allowed for 10 seconds
200 % instantaneous current allowed
220 % hardware limit ( bus fuse will blow).
400 amp 1200 volts igbt modules
650v dc bus voltage nominal
400v dc undervoltage trip
810v dc overvoltage trip
0 - 400 hz adjustable frequency
0 - 480 v adjustable voltage

i think this will be more than adequate for driving a 25 horses nominal motor.

I have a very similar unit but lower power 40 hp I think a second unit I striped the parts ( missing the caps) . The point is the case, cooling fins and fan are very heavy at least 1/2 the weight . So with a liquid heat exchanger (box) and alu case it will be much lighter and a little smaller .

yes. case weighs 60 lb, but it has the big heavy dc choke. heatsink is 29 lb, and im considering a 10 lb flat plate aluminum, same size, for modding to liquid cooling.

busy day today..

first, made sure drive works like its supposed to. took half the day to find out that the precharge board was faulty. (no wonder drive was so affordable) unplugged it, hooked up my own rectifier/precharge system, then motor, and drive works great.

Attachment 13560

then began the teardown and cleaning;

shripped it down all the way to the bare case. this assembly ; chassis, dc choke, connectors weighs around 60 lb

this is all i need out of the chassis assembly, after lots of cutting, cleaning and assembly;

and this is the finished product. coming in at 61 lb, and half the size of the original drive. now i can carry it around easily, and it fits in the hood/trunk of my conversion.

i kept the 30lb heat sink, but not before i imaged a template of all the screws/holes on it, for a liquid cooled heat sink idea later down the road.

Nice, does the drive have torque mode?

[DDDvvv]

after much research at allen bradley tech documents, i finally found this statement "......... since the 1336s drive does not support torque mode .............."

it will be hooked up with a motor encoder, so thats no big issue for me.

[DDDvvv]

just another little update**

i finally figured out how to lower the voltage on this drive. went down all the way to 100 vdc. its a simple solution, i cannot beleive that it took me this long to form in my head.

i was not looking forward to sourcing/buying/installing a 650 vdc battery pack. will detail the procedure once i figure out how to draw diagrams.

I am very interested in your project. I have a question for you could you tell me the part # of the IGBT out of the first two 1336 AB drives I am also looking to convert one?

[DDDvvv]

if you mean the original device, its a 6mb130-e or something. theres an image of it on page 2 of this same thread.

its great to see someone trying out this project. but i abandoned the idea of converting a 3hp drive, and went for a 100hp drive instead. its waaay easier to convert, and everything is already built to handle the high power.

ill be glad to help.
