  12. New EV Charger Design - Modular

    Batteries and Charging
    After delving deeply into the EMW 12 kW DIY charger, I think it would be best to make a new design. My concept is to make modules, each of which can be used on 120 or 240 VAC single or three phase, or up to 300 VDC. The modules would be 1.2 kVA for 120 VAC, and 2.4 kVA for 240 VAC or 300 VDC...
  13. Vtec just kicked in!

    Electric Motors
    Electric motors by nature are very torquey and normally have more torque that horsepower. I was thinking about how Honda engines have very low torque and have to be revved to the stratosphere to get max power out of them. I was curious as to if an electric motor be engineered to mimic this. Vtec...

  20. abb controller

    Hey, I'm toying with the idea of using an old ABB industrial controller to run a small ac motor in a small car. I've heard you can use DC as an input source into the ac power input to the drive, the drive then converts the ac to dc anyways, then reconverts it to the AC it likes to drive the...
