Sensorless position control of permanent magnet motors with pulsating current injection and compensation of motor end-effects [PDF]
, 2011 The sensorless position control of permanent-magnet motors is successfully implemented by superimposing a high-frequency voltage signal on the voltage reference or adding a high-frequency current signal to the current reference.

PERMANENT-MAGNET INDUCTION GENERATORS: AN OVERVIEW [PDF]
Journal of Engineering Science and Technology, 2011 The advantage of using a permanent-magnet induction generator (PMIG) instead of a conventional induction generator is its ability to suppress inrush current during system linking when synchronous input is performed.

Estimation of Saturation of Permanent-Magnet Synchronous Motors Through an Energy-Based Model [PDF]
, 2011 We propose a parametric model of the saturated Permanent-Magnet Synchronous Motor (PMSM) together with an estimation method of the magnetic parameters. The model is based on an energy function which simply encompasses the saturation effects. Injection of

Performance estimation of interior permanent-magnet brushless motors using the voltage-driven flux-MMF diagram [PDF]
, 2006 The flux-magnetomotive force (flux-MMF) diagram, or "energy conversion loop," is a powerful tool for computing the parameters of saturated interior permanent-magnet brushless motors, especially when the assumptions underlying classical dq theory are not ...

Permanent Magnet Brushless Drives [PDF]
IEEE Industry Applications Magazine, 1998 The purpose of this paper is to present an optimal efficiency control scheme for constant power operation of phase decoupling (PD) PM brushless DC motor drives. The key is to adaptively adjust the advanced conduction angle to minimize the system losses for a given operation point in the constant power region.

Stator iron loss of tubular permanent-magnet machines [PDF]
, 2005 While methods of determining the iron loss in rotating permanent-magnet (PM) machines have been investigated extensively, the study of iron loss in linear machines is relatively poorly documented.
