DC Universal Motor Control – Migrating to High PerformanceEE Times, December 5, 2013
The migration from an AC universal motor drive to a DC drive is not unlike the migration from a circa-1980s Chevrolet Caprice Classic station wagon to a brand-new Audi Quattro.

With the Audi, there are significant performance improvements to be gained. It offers a far more nimble, responsive, and efficient drive. The Audi is quieter, its power plant more sophisticated. It’s a fantastic car for those who can afford it, just as a DC drive is an excellent choice for demanding universal motor applications in which cost takes a back seat to performance.
