The electrical propulsion system as the core component of solar-power Unmanned Aerial Vehicles (UAVs) for long duration flight requires high power density and stable drive technology. Brushless DC motors (BLDCM) with high power and torque density and control algorithms suitable for drive system are given preference for the application in UAVs. This dissertation is aimed at designing an improved BLDCM using only 4 interior magnet blocks to realize 8 poles compared to the conventional 8 magnet blocks structure. The performances of both BLDCM designs have been analytically determined and the motor models were verified through finite element software in ANSYS. Design and construction of the demonstrators of BLDCMs with the proposed and the conventional magnet structure have been carried out and a test bench for extensive performance comparison has been set up. Since the proposed magnet structure leads to a particularity of the magnetic circuit, the behavior of absolute and differential synchronous direct and quadrature inductances have been investigated by finite element model analysis and experiments. Efficiency maps were generated and thermal characteristics have been measured to gain a comprehensive understanding of the two motors. To reduce the uncertainty of sensor control for BLDCM, a high speed, good linearity analog isolation circuit to measure the voltages of 270 V DC voltage to realize sensorless control strategy has been designed. The circuit combines a PI controller with fast operational amplifiers with a built-in linearizing feedback photodiode loop of a linear optocoupler. A 3D stator model was built to analyse the mechanical resonance frequencies and possible excitation by the electromagnetic radial force leading to vibration and noise for the proposed and conventional rotor structure. Analytical calculation of natural mode frequencies has also been conducted to compare and validate the accuracy of FEM simulations and impact hammer testing experimental results. Das elektrische Antriebssystem als Kernkomponente von unbemannten Solarflugzeugen (UAVs, Unmanned Aerial Vehicles) für Langzeitflüge erfordert eine hohe Leistungsdichte und robuste Antriebstechnik. Bürstenlose Gleichstrommotoren (BLDCM) mit hoher Leistungs- und Drehmomentdichte sowie dafür angepasste Regelalgorithmen werden daher bevorzugt in UAVs eingesetzt. Diese Dissertation zielt darauf ab, einen verbesserten BLDCM mit nur 4 eingebetteten Magnetblöcken zu entwerfen, um 8 Pole zu realisieren im Vergleich zu der herkömmlichen Struktur mit 8 Magnetblöcken. Das Verhalten beider BLDCM-Designs wurde analytisch ermittelt und die Motormodelle mit Hilfe von Finite-Elemente-Software in ANSYS verifiziert. Design und Konstruktion der Prototypen mit der vorgeschlagenen und der herkömmlichen Magnetstruktur wurden durchgeführt und es wurde ein Prüfstand für einen umfassenden Leistungsvergleich aufgebaut. Da die vorgeschlagene Magnetstruktur zu einem Magnetkreis führt, bei dem die entgegengesetzten Pole keine Spiegelsymmetrie aufweisen, wurden die Längs- und Querinduktivität durch Finite-Elemente-Modellanalyse und Experimente absolut und differentiell untersucht. Weiterhin wurden Wirkungsgradkennfelder erstellt und das thermische Verhalten untersucht, um ein umfassendes Verständnis der beiden Motoren zu erhalten. Um das sensorbedingte Ausfallrisiko zu eliminieren, wurde eine schnelle analoge Isolationsschaltung mit hoher Linearität und Stabilität zur Messung der gepulsten Spannungen bei 270V Gleichspannung entwickelt, um eine sensorlose Steuerungsstrategie zu realisieren. Die Schaltung verwendet einen linearen Optokoppler mit integrierter Rückkopplungsfotodiode, sowie einen PI-Regler mit schnellen Operationsverstärkern im Rückkopplungspfad. Ein 3D-Statormodell wurde erstellt, um die mechanischen Resonanzfrequenzen und die mögliche Anregung durch die elektromagnetische Radialkraft zu analysieren, die zu Vibrationen und Geräuschen bei der vorgeschlagenen und herkömmlichen Rotorstruktur führt. Es wurde auch eine analytische Modalanalyse durchgeführt, um die Genauigkeit von FEM-Simulationen und experimentellen Ergebnissen mit dem Impulshammer zu vergleichen und zu validieren.
