| 摘要 |
The present invention relates to a rotary machine generating a sinusoidal current, made with laminated metal sheets with low hysteresis and rotationally driven by a mechanical energy source, supplied by an electronic device which is comprised of: a sinusoidal reference oscillator (10) delivering a pilot voltage (Upil) of constant frequency; a comparator (25) comparing the voltage (Upil) with the induced voltage (Uind); a sinusoidal power inverter (11) supplied by the voltage (Uind) and delivering a control voltage (Ucom); a phase-shifter (12) making (Uind) in phase with (Ucom); a start-up circuit (15) supplied by a battery (14), delivering a current (Iaux) to an auxiliary winding (16) in phase with (Uind); a bipolar on-off switch (18); a low voltage supply (20) from (Uind).
