Hello! I'm working on an experimental alternating current generator project and need specific equations to calculate voltage and current output from a permanent magnet driven inductor, so I will have an idea what to expect before I commit real money to expensive materials. the only variables in the equations should be those which I can directly control and measure : using the symbols below : S - wire cross section area ( mm² ) t - total number of turns L - number of winding layers W - turns per winding layer R - coil DC resistance (Ω) C - coil diametre ( mm ) H - coil height ( mm ) c - core diametre ( mm ) h - core height ( mm ) T - magnetic flux density ( T ) M - magnet diametre ( mm ) m - magnet height ( mm ) a - polar reversals per second ( 1600 / s ) g - gap between rotor magnet and stator coil inductor ( mm ) A - output current ( A ) V - output voltage ( V ) K - ambient temperature ( 293.15 K ) P - core permeability ( mH ) design component values : alternating polarity permanent magnets mounted parallel to the rotation axis near the rim of the rotor. rotor magnets : 30 mm Ø x 30 mm sintered N52 grade Neodymium magnet flux density : 1.5 T inductor core : 12 mm Ø x 12 mm soft iron core permeability : 80? mH inductor coil : 12100 turns of 0.106 mm Ø polysol insulated copper magnet wire 110 windings x 110 layers coil resistance : 2 Ω / m x 912 m = 1824 Ω DCR thanks in advance!
