  1. Controllers
    Hello everyone! I'm looking for a VFD to pair with a 15kW three phase induction motor rated at 230/460V and 48/24A continuous (460V * 24A = 11040W < 15kW :confused:). The thing is, I looked into the motor's specs, and it has a starting current of 165.8A, and I can't seem to find a VFD with a...
  2. All EV Conversions and Builds
    I'll start with the basic info: • Top vehicle choices (currently): Honda CRX or Mini Cooper S • I have 3+ yrs experience as a Mechanical Engineer (CAD, Fabrication). Just a small portion has covered electrical, but nothing on the scale of an EV conversion • Desired range is at least 60 miles •...
  3. Batteries and Charging
    I have a 96 v dc agm pack, solitron jr controller, advanced DC brushed motor rated @120v. sports car (Lotus). I would like to add regen braking. But, newbie question: The motor spins backward to become a generator during braking? Managed by the controller. I don't understand the physics --...
  4. Batteries and Charging
    Hi Guys, example: I have 10 Lithium Ion Cells in parallel = 2.2Ah each * 10 = 22Ah (@3.7V) if i want to charge these cells like they are - what will be the maximum charging current ? all help welcome.
  5. Technical Discussion
    There were some other threads related to this, but I think the specific subject of the nominal current rating of various wire sizes, and the ability to handle overloads above those ratings, deserves separate attention. I just ran a test of #16 AWG magnet wire, which is conservatively rated at...
  6. Batteries and Charging
    I'm sure this question would have been asked before but i can't for the life of me find the thread. i was looking into thundersky batteries mainly because there one of the cheapest lithium going around, and the seem to be good quality. with a long life 3000 cycles (10ish years) with a high max...
  7. Controllers
    Anyone familiar with the C like language of arduino? I am currently using it for my microcontroller and could really use some help with the over current protection part of it int potPin = 2; // select the input pin for the potentiometer int ledPin = 11; // note onlly 5,6, 9,10,11 are...
  8. Controllers
    Here is a newbie question: Lets say that we have a PWM controller that is current limiting. What is the purpose of the current limiting? Is it to protect the MOSFETs in the controller or the motor? Thanks
