➀ Researchers at Graz University of Technology have developed more efficient and quieter miniature electric motors through innovative design, improved control technology, and new production techniques. These motors are used in a wide range of household appliances, tools, computers, and modern cars. ➁ The team reduced vibrations by modifying the claws of the motors, leading to a 70% reduction in noise. ➂ They also simplified the regulation of current flow, reducing switching losses and improving overall efficiency. The motors now require fewer capacitors, lowering costs.
