The article discusses the emergence of the permanent-magnet traction motor in the railroad industry. This technology has been increasingly adopted due to its benefits in terms of mass, size and energy consumption despite issues regarding complex control systems and potential failure modes. It was pointed out that despite the conservative nature of railway operators in technology adoption, rail traction system manufacturers and designers are keen on using the latest drive technologies.
