A back-electromotive force (EMF) model reference adaptive system based sensorless control scheme is proposed for a grid-connected doubly fed induction generator (DFIG). Based on the stator-side and the rotor-side dynamic models of the DFIG, both the reference model and the adaptive model of the proposed back-EMF based DFIG are investigated.

Al-Ca master alloy was prepared by molten salt electrolysis method, using a mixed molten salt system of CaCl2-CaF2 and feeding CaO as electrolysis material. The technological parameters such as back electromotive force (BEMF), cell voltage, and current were measured by testing device of molten salt electrolysis.

The magnetically levitated system, so called maglev system, has been researched and developed with the purpose of vacuum compatibility in the semiconductor industry. In the maglev system, the back electromotive force is inevitably generated when the system moves. The back electromotive force causes force/moment disturbances.

Uneven magnetization of permanent magnets (PMs) is one of the major sources of unbalanced magnetic force and torque ripple, which excite a brushless dc (BLDC) motor. This paper investigates the frequency contents of the back electromotive force (BEMF) due to the unevenly magnetized PMs in a BLDC motor.

Journal of Vibration and Control
This paper presents the modeling and analysis of electromagnetic vibration and noise in permanent magnet synchronous motor (PMSM) under the influence of nonsinusoidal back electromotive force (back-EMF). First, the actual back-EMF of the prototype and the current distortion induced by it are experimentally analyzed.
