With the merits of low power loss, high torque density and high power density, permanent magnet synchronous motors (PMSMs) have been widely applied in various areas. In many applications, the PMSMs are requested to operate with high efficiency over wide speed and load ranges, so the study on proper core loss prediction has attracted much attention for the modeling, design, optimization and control of PMSMs. However, the equivalent circuit model, which is usually applied for motor performance analysis with fast calculation, rarely considers the core loss. This paper presents improved performance analysis of a permanent magnet transverse flux motor with soft magnetic composite stator, based on a modified equivalent circuit model considering core loss. Compared with the experimental measurements on the motor prototype, the performance prediction accuracy based on this new circuit model is much higher than that based on conventional circuit model without core loss.
