Steps for calculating dc generator output potential

  1. Mar 9, 2009 #1
    I need help understanding a few different items regarding electromechanics, and I'm not really sure where to start. Though the figures I have provided immediately seem impractical (coil melt down, coil explosion due to excessive rpm, inside dimensions exceeding their respective outside dimensions when certain figures are added together, ect), they are the numbers I must work with.

    Wire properties:
    Enamel copper motor wire.
    AWG 24 (0.0201 in dia).
    Wire length: 40,000 feet
    Turns of wire in coil: 46462.84
    Coil RPM: 18,364,800
    Coil distance from magnets: .05 inches

    Magnet properties:
    Material: Neodymium
    Pull Force: 705.23 lbs
    Surface Field: 5630 Gauss
    Brmax: 14,800 Gauss
    BHmax: 52 MGOe

    I am unsure if magnetic fields "stack" (double, triple, ect) when they are close or put together, but if they do then assume that two of those magnets are .6 inches in distance from and parallel to, each other. Also assume that the coil is .5 inches in width and would be between those magnets.

    Basically, how would I even start calculating the types of output this would generate? Volts, watts, amps -- you name it.

    Thanks in advanced. :)

    Do you think the appropriate first steps would be something along the lines of this.

    What are dimensions of this generator? Is the copper wound on a stator or on an armature? Does the generator have a commutator or slip rings on the armature? Does the generator have diode rectifiers (like an automobile)? Does the generator have a neodymium magnet armature? Do you commutate the exciting current with a Hall effect probe? Your RPM is much too high.
