Abstract
This thesis explores the integration of position sensors in a high performance micromotor, characterized by its compact design with windings printed on a flexible PCB. Such motors are prevalent in various applications and require precise rotor position information for optimal performance. The research provides a theoretical background on the motor's topology, its benefits, and the necessity of position sensors. A review and comparison of different sensor configurations from existing literature were conducted, followed by simulations in COMSOL Multiphysics to identify optimal sensor placement. Two configurations were selected for real-world testing, with the most accurate and error-resistant configuration being identified. Further signal processing techniques were evaluated to enhance positioning accuracy. The findings demonstrate the feasibility of integrating a high-precision, low-cost positioning system in compact motors, contributing valuable insights for future advancements in motor design and control.
