  • Load Torque Estimation in Permanent Magnet Synchronous Motors Using Artificial Neural Networks

    This work proposes the use of a neural network for estimating the load torque of a Permanent Magnet Synchronous Motor (PMSM) based on its line currents. Traditional methods for torque estimation typically rely on mechanical sensors or complex mathematical models, which can be expensive and difficult to implement. The proposed method using a neural network offers a more cost-effective and can be implemented on a dynamometer test bench for a machine, providing a reliable means of estimating torque in real-time. This approach not only eliminates the need for costly torque transducers but also allows for continuous monitoring of line currents, leading to precise torque estimation. Overall, this work presents a significant improvement in the efficiency and cost-effectiveness of torque estimation for PMSMs, with potential applications in research, development, and industrial testing environments.
  • Study and Development of Photovoltaic Power Generation System for Hybrid Refrigeration Units Applied in Refrigerated Semi-Trailers

    SAE Technical Papers, 2023
    <div class="section abstract"><div class="htmlview paragraph">This article presents the development of a solution that uses solar energy to power refrigerated semi-trailers. The solution employs photovoltaic cells on the surfaces of the semi-trailer, combined with a battery pack, which take advantage of a significant area with solar exposure and generate sufficient electric power to supply the refrigeration unit responsible for controlling the temperature inside the climate-controlled chamber. In addition to providing energy for the refrigeration unit, the solar system can be integrated with the auxiliary traction system used in some semi-trailers, functioning as a range extender for the battery. To achieve the main objectives of this development, studies were conducted to evaluate solar radiation through simulations considering different regions of Brazil. A hardware system was also developed for energy management and to drive the refrigeration unit, combining a high-power drive system composed of filters, DC/DC converters, and transformers to match the voltage levels of the systems, with a microprocessed circuit for functional logic control. As a result, a system capable of operating the refrigeration unit using solar energy was obtained, which can reduce diesel consumption by up to 1800 liters per year.</div></div>
