Re: Tesla Large Drive Unit Support Thread

I am planning on using a fuse rated at 30A 450V for the 120v and 380 volt low speed tests. I have the frequency maxed at 100Hz and I had no intentions of moving it much farther than that. I am certainly not going to be introducing regen on the bench if I don't have to. I see people doing high RPM no...

Re: Tesla Large Drive Unit Support Thread

Now that I am all set for my circuit protection for the 120v test (thank you muehlpower!) I wanted to ask ahead of time about the current draw that can be expected during the full voltage test which is my next step. Is it still below 30A on the unloaded motor or do I need to step up the circuit prot...

Re: Tesla Large Drive Unit Support Thread

I am currently using a 30A automotive breaker that I am assuming is rated for 12/24v. It held up perfectly with the 50v setup but I'm not sure how it will like 120v even at the low amperage of the unloaded motor. I ordered a small set of insulated tools that should be all I need for connecting the b...

Re: Tesla Large Drive Unit Support Thread

What is the recommended wire gauge to use for a 120v bench test run using 5 S3 battery modules? Is 10 gauge wire sufficient? I am assuming the amperage draw will still be low, below 30A.

Also is it imperative that one use insulated tools assembling a battery array at voltages over 50VDC?

Re: Tesla Large Drive Unit Support Thread

Got all my problems solved and had a successful test. The panzer parameters saved the day! Now on to the next step, testing at 120 volts using some of my S3 modules. Thank you to the few who chimed in to point me in the right direction.

Re: Tesla Large Drive Unit Support Thread

I guess I was too focused on his wiring at the time trying to figure out the small relays he had on his test board. I will have to get a few more batteries then! Thanks for pointing that out. I could have watched the video again and I still would have most likely missed that lol.

Re: Tesla Large Drive Unit Support Thread

While that certainly makes sense the reason I chose 12v was because that is exactly what was used in this video: https://www.youtube.com/watch?v=7Ol8Mdw7Blg and it seems to work just fine for an initial low speed test. I do not see any other power source in it and everything seems to be wired to the...

Re: Tesla Large Drive Unit Support Thread

Hey everyone, new guy here but no noob to electricity or cars. I have a P85D setup I am performing low voltage testing to. I based my bench test off of Roadstercycle's youtube video and the diagrams posted on this thread. This thread was very much instrumental in getting as far as I have! I have a 1...
