AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
NOVELTY - After disconnection from normal control (3) a pulse generator (4) sends positive and negative pulses to a motor winding R. The response currents are measured (5) from voltages (Vpr,Vnr) which appear after a fixed time on a neutral resistor (2) an ...
The number of brushless DC (BLDC) motor applications has increased significantly, essentially due to reduced costs of semiconductors and permanent magnets, but also because of the emergence of new control strategies, such as closed-loop and sensorless cont ...
Usually, each phase of the direct reluctance motor is fed separately by its own inverter producing a squarewave phase current depending on the rotor position. In the present work, a star-connection of the three stator phases is used and the direct reluctan ...
To design actuators or motors requires analyzing a lot of parameters such as length, temperature, efficiency, weight, etc. To obtain the optimum results for given specifications the solution is to analyze globally all the free parameters in one go, with an ...
In this article a high performance Extended Kalman filter algorithm is used to estimate rotor speed, rotor position and load torque in a Hybrid Stepper Motor (HSM). Together with a PI speed controller, the Kalman filter forms a very robust sensorless close ...
Extended Kalman filtering techniques have been successfully used as sensorless control schemes on many different types of synchronous motors. One big disadvantage of the extended Kalman filtering technique is the large computational cost. Even with today's ...
The aim of the present paper is to extend the well-known complex torque coefficient method usually used for synchronous machine rotor oscillations, to a slip energy recovery induction motor drive. To illustrate the effectiveness of the proposed extension, ...
Based on a mathematical model, simulation results show how the mechanical performances of the motor are sensitive to the prestressing force. A test bench has been developed in the laboratory for experimental measurements. The motor is driven by a two-phase ...
In many applications, industry has tried to develop sinusoidal supply for brushless DC (BLDC) motors. This paper describes a method that still keeps a simple 2 phases-on sensorless method and achieves sinusoidal supply, which is needed to avoid speed oscil ...
The present paper presents an automatic approach for the determination of the parameters of laminated salient-pole synchronous machines, based on 2D finite element method (FEM). Calculations using FEM are performed in rotation (sudden three-phase short-cir ...
