“…The integration of a grid side passive LCL filter into the stator back iron of a permanent magnet synchronous machine produces high power density, according to the Authors of [7,[28][29][30][31]. As shown in Figure 16a, both inductors (L1 and L2) are wound into the double slot machine's outermost slots.…”

With the increased necessity of a high power density and efficient system in aerospace and marine industries, integrated motor drives provide an excellent solution in the modern era. Therefore, a close structural and functional integration of passive components has become a prerequisite task to make a compact overall system. This article reviews the existing motor drives system with integrated passive technologies. To start, the design aspect of the traditional and integrated filter inductors, using the area product approach, is discussed. Subsequently, layouts of traditional and integrated inductors are presented. The available capacitor technologies, suitable for integration, are also discussed with pros and cons of each capacitor type.

“…If the stator back iron of the machine is operating linearly then the presence of ring flux due to toroidal winding will not affect the main flux. Authors of [16,17] presented a structural integration of grid side passive LCL filter into the high-speed PMSM which achieves high power density. Both inductors are wound into the outermost slots of the double slot machine.…”

A close functional and structural integration of passive elements is required to improve the power density of motor drives. Such power dense motor drives are prerequisite in aerospace and automotive applications. This paper presents a permanent magnet motor with integrated filter inductor, which not only eliminates inductor losses but also removes its associated weight and volume. The motor with integrated filter uses motor's inherent magnetics in order to use it as a filter inductance instead of adopting an external inductor option, which is traditionally placed outside the motor. A vector-controlled model, taking modulation and switching effect into account, has been developed by using MATLAB/Simulink tool. To experimentally validate the concept of the motor with integrated filter inductor, the winding connections of an existing motor are modified. The comparative analysis, between the traditional and integrated motor drive systems, is carried out in terms of magnitude of switching component, total system losses, weight and volume. The total losses in the motor with integrated filter are reduced by 34.2% at 2100rpm and 3Nm load, when compared to the motor with traditional filter inductor, whereas, its weight and volume in the motor with integrated filter inductor is eliminated completely.
