Summary:This paper describes a method to estimate the performance and active mass of a coreless Axial Flux Permanent Magnet (AFPM) machine for integration in aircraft propulsion systems. The use of coreless AFPM machines has many advantages. Mainly, the high efficiency due to the elimination of the core losses and natural convective refrigeration air flow. Both leading to high power per unit mass. The determination of the motor constant considers the circuit flux linkage distribution from 2D Finite Element Analysis (FEA). The Back Electromotive Force (BEMF) waveform is also obtained. A simple model for estimating the motor active mass is implemented in an effort to implement a motor design parametric study of the ratio K V /active mass as the motor Figure of merit. The proposed methodology is compared with experimental results of a similar electrical machine.
