A test stand to measure the magnetization work of magnetocaloric materials
(Revista De Saude Publica, 2016)
The experimental apparatus presented in this study is capable of precisely measuring the magnetic force produced by a permanent magnets assembly over a magnetocaluric material at a regulated temperature. This data is then ...
Nonlinear control of a permanent magnet synchronous motor with disturbance torque estimation
(Institute of Electrical and Electronics Engineers, 2000-06)
This paper introduces a sensorless nonlinear control scheme for controlling the speed of a permanent magnet synchronous motor (PMSM) driving an unknown load torque. The states of the motor and disturbance torque are estimated ...

This paper aims to address a study on DC motors with permanent magnets that are used in the automotive industry, specifically for ventilation and heat balance applications. This study is divided into three stages: The first ...
Levantamento dos Parâmetros de Projeto de um Motor de Corrente Contínua sem Escovas com Ímãs Permanentes Superficiais e Rotor Externo
(Florianópolis, SC, 2019-02-15)
O presente trabalho aborda o projeto de um motor de ímãs permanentes superficiais com rotor externo sem escovas. Motores elétricos com ímãs permanentes possuem maior eficiência dentre as várias configurações de motores ...
Optimization of permanent magnet skew in permanent magnet linear synchronous motors using finite element and statistical method
(Scientific Research, 2011)
he permanent magnet skew is one of the techniques mostly used on the Permanent Magnet Linear Syn-chronous Motors (PMLSMs) to reduce the thrust ripple; even though there is a reduction in the amplitude of ripple and at the ...
