Guide / Sample Data


When making accurate calculations of coil copper loss, it is necessary to take into account current bias that occurs due to the influence of harmonics and flux leakage, both of which occur as a result of PWM control. Modeling wire geometry is required to sufficiently reproduce these current distributions.
Various combinations of motor types, the number of poles, and the number of slots are additionally investigated in the initial stage of motor design, with searches performed for the design that satisfies design requirements. By utilizing the geometry library, the winding editor, and wire templates in JMAG, parametric analyses with varying numbers of parts can also be performed for wire geometry.
This document describes the method for performing wire geometry parametric analysis for motors with the number of poles and the number of slots as design variables.
