My goal is to put a 10 KW motor 100V and 100A in the sailboat. I have tried several controllers, but I might have to upgrade the controller soon.
I am still waiting for the batteries to arrive from China, so in the waiting face I wanted to see if I could make the motor turn with only 4s LiFeO4 with only 14ah that I got laying here. I run it sensor less, and it is turning, but very strangely. I guess it takes 30 amps just to turn the motor, so maybe the BMS shuts the power off, or the ESC controller senses the drop in voltage and cuts the power. It run for 1 second, then cut of for one second, so the motor starts and run up til 100rpm, and stops and up again.
If I turn the speed potentiometer further up, it stops completely. It only runs when the pot is just starting to start the motor. I guess this is a problem that will go away when I get more batteries or not?
I just found this problem on the forum, and it looks to be close to what I got? https://vesc-project.com/node/3407
I also noticed the Flipsky 75100 started to get warm, an this was under no load. So I ordered the Flipsky 75200 with water cooling. I also ordered the waterproof remote controller for it. Then I found the Tronic 250R that can handle more than 100V. I have not ordered it yet. I want to see how Flipsky 75200 is working first. Also I wonder if the remote controller I ordered with the Flipsky will work with the Tronic 250R.
I was planing to install a sensor on the motor, but I wonder if the VESC software is so good that it will run just fine sensor less?
As you see I have a lot of questions, so if some of you got some answers fell free to comment.
