概要

The spiral vector method was applied by the author to analysis of the synchronous machine, providing new analytical solution of both steady and transient states. With respect to steady state the SV diagram was derived and it revealed new aspect of steady state performances of the synchronous machine.Permanent-Magnet-excited synchronous motors are now used as AC control motors, replacing DC control motors. Their performances are quite different from the field-winding-excited synchronous machine, and they are also different among the magnet-excited synchronous machines, depending on different arrangements of the magnets. SV method will reveal new performances of PMSM and its new control method will be proposed, as the AC control motor.
