—A remote microcontroller lab based on an 80C537 mock-up is presented. This paper presents a new way to interact with these kinds of systems via the Internet, giving the possibility for complete interaction. The Citrix Application Server is the platform which manages the debugging microcontroller software, and National Instruments LabVIEW 8 is used to… (More)
This paper presents a study of the permanent magnet synchronous motor (PMSM) running under demagnetization. The simulation has been carried out by means of two dimensional (2-D) finite element analysis (FEA), and simulations results were compared with experimental results. The demagnetization fault is analyzed by means of decomposition of stator currents… (More)
—This paper presents a new approach for the current acquisition system in motor fault detection applications. This paper includes the study, design, and implementation of a Rogowski-coil current sensor without the integrator circuit that is typically used. The circuit includes an autotuning block able to adjust to different motor speeds. Equalizing the… (More)
Double frequency tests are used for evaluating stator windings and analyzing the temperature. Likewise, signal injection on induction machines is used on sensorless motor control fields to find out the rotor position. Motor Current Signature Analysis (MCSA), which focuses on the spectral analysis of stator current, is the most widely used method for… (More)
In this paper works with no-lineal tool and computer simulations, phase-plane trajectory analysis and method of Lyapunov for evaluate the limits of the small signal models and suggest to utilize models that can permit the analysis of the system when subjected to a severe transient disturbance.
