    Designing a three phase permenent magnet generator

    Gokul43201, have you checked your private messages , i sent you one on feb 7th. i dont know who else to turn to for an answer, the gap is adjustable and is essentially the same @ 0.460" , for both tests. my test coils are 0.390" thick. i have several. 0.035" space top and bottom.. this...
