Abstract:

A two-dimensional analysis of the cross section of a homopolar inductor alternator supplying a rectifier load has been developed in Part I of this investigation. Besides the effects of the nonlinearities of the magnetic materials, the eddy currents induced in the rotor by the nonlinear load have been considered. Thus, some of the partial differences equations were parabolic. The analysis was applied for eddy currents, waveshapes, and field excitations. The calculations were made for a 95 kVA homopolar inductor alternator, 115200 V3-phase 3,400 Hz 40,800 rmin. Part II of the report deals with the computer programs used in the calculations. The use of an interactive minicomputer was most convient for the development of the computer programs and for calculations to obtain results. In order to solve the problem on a mimicomputer, a virtual memory technique for the storage of data had to be applied. The computer programs, from those for the problem setup to the display of the solution, are independent of the particular problem being solved. This facilitates the investigation of various alternatives during the design process.
