1. 1. Sensorless Hybrid Field-Oriented Control Two-Phase Stepper Motor Driver

   University essay from Linköpings universitet/Reglerteknik

   Author : Emil Lydell; [2023]
   Keywords : Stepper motor; Field-Oriented Control; FOC; Driver; Two-Phase; 2-Phase;

   Abstract : Hybrid stepper motors are small electrical motors with high torque production, compared with other electrical motors of the same size. Hybrid stepper motors are reliable in open-loop systems, in Sinusoidal mode, but with a drawback of high power consumption. READ MORE

3. 2. Substation Digitalization for Medium Voltage Urban Distribution Networks : A Techno-Economic Analysis

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Diego Molina Mendizábal; [2023]
   Keywords : Continuity of supply; incentive scheme; SAIDI; techno-economic analysis; Kontinuitet i försörjningen; incitamentsprogram; SAIDI; teknisk-ekonomisk analys;

   Abstract : High and medium-voltage digital substations play an essential role in the energy transition since they are part of the equipment required to deploy smart grids. With the gradual increase of smart grids, energy systems are becoming more flexible with the growing penetration of renewable energies and distributed energy generation. READ MORE

4. 3. Construction and Control of a 3-axisAutomated Liquid Sampling UnitUtilizing Hybrid Stepper Motors

   University essay from KTH/Mekatronik och inbyggda styrsystem

   Author : Arvid Bergvall; Pontus Lundman; [2023]
   Keywords : Mechatronics; Gantry; Stepper motor; Control; Linear Quadratic Regulator; Adaptive LQI; PID; Mekatronik; Gantry; Stegmotor; Reglerteknik; LQR; Adaptiv LQI; PID;

   Abstract : High accuracy autonomous positioning systems are becoming increasingly important in today’s chemical industry because they can obtain precise experiment results automatically and hence allow lab technicians to focus on other tasks concurrently. One time consuming process is the process of sampling chemical test results into the correct container, especially when the tests are many and infrequent. READ MORE

5. 4. Redeveloping a mixing system in a biomedical device to improve system control and increase its intelligence and effectiveness : Redeveloping a mixing mechanism using ESP32, TMC5130, Bluetooth and CAN-bus

   University essay from Mälardalens universitet/Akademin för innovation, design och teknik

   Author : Aref Bahtiti; [2023]
   Keywords : CAN-bus; Bluetooth classic; Stepper motor; TMC5130; ESP32; Open loop system; Smartphone application;

   Abstract : Biogas is a renewable energy source produced by decomposing organic matter in the absence of oxygen. Without oxygen, organic matter is broken down in this process, producing a mixture of gases that may be used for a variety of tasks, such as heating, cooking, and producing power. READ MORE

6. 5. INVESTIGATING THE TOXIC AND ACIDIFYING EFFECT OF SCRUBBER EFFLUENT ON STRONGYLOCENTROTUS DROEBACHIENSIS LARVAE

   University essay from Göteborgs universitet / Instiutionen för biologi och miljövetenskap

   Author : Ida Vartia; [2022-09-28]
   Keywords : ;

   Abstract : To meet the new environmental requirements of reduced sulfur emissions from ships, many shipowners have installed an open-loop scrubber to clean the exhaust. In this scrubbing process, seawater is pumped from the ocean and combined with the emission gas, creating an acidic and toxic effluent that is directly discharged into the ocean, potentially damaging the marine environment.
