question: How does a brushless wound rotor achieve stability ?
answer: a multiphase slip-ring-brush assembly to propagate limited power to the rotor winding set
turker_answer: A brushless wound rotor achieves stability with a multiphase slip-ring-brush assembly to propagate limited power to the rotor winding set .
rule-based: A brushless wound rotor achieves stability by a multiphase slip-ring-brush assembly to propagate limited power to the rotor winding set .
