PCT No. PCT/AT92/00049 Sec. 371 Date Nov. 2, 1993 Sec. 102(e) Date Nov. 2, 1993 PCT Filed Apr. 8, 1992 PCT Pub. No. WO92/19038 PCT Pub. Date Oct. 29, 1992Method and apparatus for accurately determining electromagnetic and mechanical information from electrodynamic rotary field machines, such as, for example, asynchronous, synchronous or reluctance machines that utilize voltage discontinuities generated by an associated inverter. The apparatus according to the present invention obtains information from machines running at a low rpm without using a mechanical transducer, as well as with machines running at a high rpm.
