In our contribution we deal with the optimization of the magnetic circuit design of the high torque step motor by numerical solution of the motor magnetic field (the Finite Elements Method — FEM) and with the solution of some electrical parameters of this motor and we introduce the methodology of optimization of the motor size from the parameters dependant.

The analysis of the magnetic field and computation of the leakage magnetic flux is important for optimum design of the motor, especially for the small machines on low voltage loaded from the accumulator battery. In our contribution we analyzed the computation of the leakage magnetic field and flux by means of analytical, respective numerical methods (Finite Elements Method — FEM).

The following classified, annotated list of titles is intended to provide reference librarians with a current checklist of new reference books, and is designed to supplement the RSR review column, “Recent Reference Books,” by Frances Neel Cheney. “Reference Books in Print” includes all additional books received prior to the inclusion deadline established for this issue. Appearance in this column does not preclude a later review in RSR. Publishers are urged to send a copy of all new reference books directly to RSR as soon as published, for immediate listing in “Reference Books in Print.” Reference books with imprints older than two years will not be included (with the exception of current reprints or older books newly acquired for distribution by another publisher). The column shall also occasionally include library science or other library related publications of other than a reference character.
