A compact and tunable atomic magnetometer for femtotesla radio-frequency field detection
(Universitat Politècnica de Catalunya, 2022-07-19)
Projecte Final de Màster Oficial
Accés obert
Realitzat a/amb: Universitat de Barcelona / Universitat Autònoma de BarcelonaWe demonstrate an ultra-high sensitivity rf optical magnetometer based on a compact 5×5×8 mm3 Rubidium-87 vapor cell in a mu-metal shielded environment. The rf field is detected via a Faraday rotation effect on the linear ... -
Control óptimo de par para máquinas SynRM aplicadas a vehículo eléctrico
(2017)
Comunicació de congrés
Accés obertLas máquinas de reluctancia síncrona asistidas por imanes están atrayendo un considerable interés como alternativa a las máquinas síncronas de imanes permanentes para su uso en sistemas de propulsión de vehículos eléctricos. ... -
Detection of partial demagnetization fault in PMSMs operating under nonstationary conditions
(2016-07-01)
Article
Accés obertDemagnetization fault detection of in-service permanent magnet synchronous machines (PMSMs) is a challenging task, because most PMSMs operate under nonstationary circumstances in industrial applications. A novel approach ... -
Magnetic localization system for short-range positioning: a ready-to-use design tool
(2021)
Article
Accés obertMagnetic localization is used in many indoor positioning applications, such as industrial, medical, and IoT, for its benefits related to the absence of line of sight needs, multipath and fading, the low cost of transmitters ... -
Multivariate identification of extruded PLA samples from the infrared spectrum
(Springer, 2020-01)
Article
Accés obertPolylactic acid (PLA) is a biodegradable thermoplastic polymer that is presented as a good alternative to petroleum-derived plastics. Some of the major drawbacks of this material are its lack of thermal stability and rapid ... -
Puesta en marcha del control de una bancada de ensayos para generadores síncronos de imanes permanentes
(Universitat Politècnica de Catalunya, 2019-05-22)
Treball Final de Grau
Accés restringit per decisió de l'autorInicialmente, me ofrecieron realizar mi trabajo de final de grado sobre un banco de pruebas que se encontraba en estado de des uso por falta de dedicación y de algunas piezas esenciales para su funcionamiento.Este ... -
Reducing the cogging torque effects in hybrid stepper machines by means of resonant controllers
(Institute of Electrical and Electronics Engineers (IEEE), 2018-06-11)
Article
Accés obertPermanent magnet machines are not free from the interaction between magnets and the stator and rotor slots, which causes an undesired disturbing torque. Such cogging or detent torque is especially larger with salient pole ...
