“…Since the reduction in filter branch inductance increases the weight and volume of the filter capacitor therefore, from application requirement point of view, it is necessary to select the filter's parameters at which both weight and volume are minimum. The total system weight can be obtained from (15) to (16).…”

“…Inductors integrated onto the power modules substrate are presented in [16,17] with an aim of integrating inductor on power module substrates along with the switching devices, to increase its power density and improve thermal management. The concept is to make a bonding copper U-shapes which is representative of single winding turn on the substrate that enhances thermal exchange between the inductor and the cooling system, leading to an increased current density and hence reduction in mass and volume.…”

The present trend of aerospace industries is being shifted towards a “More Electric Aircraft” system which needs to be high power dense. For this purpose, the integration technologies have gained massive interest, providing the benefits of reduced losses, weight, volume and cost. In this article, the integration concept of a passive filter inductor is presented for a permanent magnet synchronous motor. The integrated motor eliminates the need of an external inductor, thus, eliminates the added inductor losses, mass, volume and cost associated with it. The motor utilizes its’s inherent inductance to use it as a filter inductor instead of implementing a discrete inductor that is commonly placed between inverter and the motor terminals. Optimization study is carried out, where the filter branch windings are tapped, in terms of improving mass and volume and performance parameters such as power losses and torque ripple. From the optimization study, the motor with minimum weight and volume is experimentally validated at the rated conditions, in order to prove the concept feasibility. Total system weight and volume of integrated and traditional motor drives are compared, which gives the minimum weight of 2.26 kg and 3.14 kg respectively, and the minimum volume of 0.54 L and 1.1 L respectively.
