摘要：
Methods and apparatus are provided wherein air gap flux magnitude and relative position are determined from stator voltage harmonic components and stator current in operating alternating current machines having a stator, a rotor and an air gap therebetween. Such determinations have various uses, such as for efficiency control. Various new and improved efficiency controllers are provided which utilize these measurements.
