Abstract
A cageless reluctance motor having nonsinusoidal space distributions is analyzed. Inductance variations of several cageless reluctance-synchronous machines for high-speed drives were measured. Based on the results of the measurements, the direct and quadrature-axis inductances are predicted using derived expressions. In addition, these are also predicted by the conventional method and compared with the machine parameters obtained by the load tests. The inductance equations were used in the measurement of parameters of the test machines, and their validities were experimentally confirmed. The proposed method is found to predict accurate unsaturated machine parameters.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
