    I have an old three phase motor with only three spots for wires - no neutral. It is a three-phase 110V AC motor. I want to hook it up to my bike to make electricity. I can hook it up, but I need help with designing the schematics. I want to be able to power normal appliances with the bike so since...

  • Control Board Inside the PIM for GM's Old EV1 Car

    I am looking for detailed schematics for the control brd located inside the PIM of the ev1. The PIM is the box that uses 300Vdc input (from batteries/rectifier) and converts the DC into 3 phase variable frequency AC output, to run the main motor (inductive motor). I converts DC to AC by use of a 3 p...

  • Re: 1 Phase To 3 Phase

    hiii all, to be precise, simply, capacitors wont do the job. if one can design an RC phase shift oscillator for power frequencies, it would be fine since these oscillators are used only in the audio frequency range so far as i know. and again, a possible solution may be to give the single phase...

    I have done it for some years ago. I had a float in the tank who break the power to the pump when the level was near minimum. You can monitor if the pump is shut down and you may to start it by hand. Do you want a schematic diagram? Is the AC motor one- or three phase and what is the voltage to it?
