A new technique to control brushless motor for blood pump application
(BLACKWELL PUBLISHING, 2008)
This article presents a back-electromotive force (BEMF)-based technique of detection for sensorless brushless direct current motor (BLDCM) drivers. The BLDCM has been chosen as the energy converter in rotary or pulsatile ...
Power Flow Maximization in Permanent-Magnet Generators
(Institute of Electrical and Electronics Engineers, 2014-02)
The main hypothesis proposed in this paper is that by controlling the harmonic and zero-sequence components of the current in nonsinusoidal permanent-magnet synchronous generators (PMGs), additional energy can be obtained, ...
Effect of oxytocin on transepithelial transport of water and Na+ in distinct ventral regions of frog skin (Rana catesbeiana)
(Springer, 1996-06-01)
Thoracic, abdominal, and pelvic fragments of ventral skin of Rana catesbeiana were analysed regarding the effect of oxytocin on: (1) transepithelial water transport; (2) short-circuit current, (3) skin conductance and ...

Estudo de um sistema de controle sensorless para máquinas síncronas de ímãs permanentes internos
(Universidade Federal de Santa MariaBrasilUFSMCentro de Tecnologia, 2023-03-06)
This paper presents a study of state observers for the control of permanent magnet synchronous electric machines. In order to ensure the correct functioning of the machine, control techniques employed in PMSMs require ...
