Tiivistelmä
The purpose of this thesis work was to design hardware for BLDC motor controller for Oceanvolt’s new HighPower ServoProp system. The BLDC motor controls the controllable propeller blades of the saildrive to optimal angles while sailing, maximizing energy recovery during regeneration. The goal was to design a prototype printed circuit board (PCB) and test its functionality with EMC test equipment in the Metropolia campus electronics laboratory, to enhance its reliability.
The thesis focuses on common electromagnetic interference (EMI) challenges in motor controller design, offering perspectives on important considerations during the PCB design phase. It provides a theoretical background on BLDC motors and driving methods, outlining potential EMI sources, and proposing solutions for their reduction.
An EMC scanner was used to detect noise sources originating from the designed PCB and to provide insight into the emission levels produced. The analysis of measurement and designed board eases the development of the designed PCB further.
