Khan, S. ORCID: 0000-0001-5589-6914 and Ivanov, A. (1992). Methods of calculation of magnetic fields and static characteristics of linear step motors for control rod drives of nuclear reactors. IEEE Transactions on Magnetics, 28(5), pp. 2277-2279. doi: 10.1109/20.179468

Abstract

The performance of linear step motors (LSMs) which are being developed for control rod drives in nuclear reactors is governed by their static characteristics. The reliability of control rod drive mechanisms and the safety of the reactor depend on reliable performance of these motors. The authors describe methods of calculation of magnetic fields and static characteristics of LSMs. Two methods have been developed, approximate and accurate. The first method, less computationally intensive, could be used for small currents and weak iron saturation, while the second, based on accurate field modeling, takes into account saturation effects which considerably affect motor performance.
