The magnetic field curved along the cylindrical surface of the winding.
Abstract
A method for calculating the potential of a compensating magnetic field (q.ms) 2p-pole (p is the number of pole pairs) curved along a cylindrical surface of a winding containing one section per pole is given. Analytical expressions are obtained for the calculation, up to a fifth-order multipole, of the magnetic potential of the PM of two-, four-, and six-pole windings. It is shown that at large distances compared to the dimensions of the winding, the magnetic potential of its CM is determined by the “main” multifield of order p. Il 2. Bibliogr .: 4 titles.
