  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. 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

  4. 3. Hardware-In-the-Loop simulation of a small scale prototype of a Wave Energy Converter

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Anton Magnusson; [2020]
    Keywords : Hydrodynamics; Hardware-In-the-Loop; WEC-Sim; Wave Energy Converter; NEMOH; Hydrodynamik; Hardware-In-the-Loop; WEC-Sim; vågenergikonverterare; NEMOH;

    Abstract : Renewable energy sources are a hot topic, both when it comes to climate change and the constant increase in demand of electricity due to population growth and a more electrified society. One such energy source is wave energy - an energy source with great potential but still relatively new with the need for further development. READ MORE

  5. 4. Detection of lithium plating in lithium-ion batteries

    University essay from KTH/Kemiteknik

    Author : Carl Johan Björkman; [2019]
    Keywords : Lithium plating; Batteries; Battery monitoring; Battery charging; Battery ageing; Litiumplätering; Batterier; Batteriövervakning; Batteriladdning; Batteriåldring;

    Abstract : With an increasing demand for sustainable transport solutions, there is a demand for electrified vehicles. One way to store energy on board an electrified vehicle is to use a lithium-ion battery (LIB). This battery technology has many advantages, such as being rechargeable and enabling reasonably high power output and capacity. READ MORE

  6. 5. Estimation and Compensation of Load-Dependent Position Error in a Hybrid Stepper Motor

    University essay from Linköpings universitet/Reglerteknik

    Author : Anton Ronquist; Birger Winroth; [2016]
    Keywords : Adaptive Notch Filter; Back-EMF; Electric Motor Position Control; Error Modelling; Field-Oriented Control; Hybrid Stepper Motor; Kalman Filter; Load Angle; Magnetic Rotary Position Sensor; Sensorless Control; Sliding Window Discrete Fourier Transform; Stall Detection and Prediction.;

    Abstract : Hybrid stepper motors are a common type of electric motor used throughout industry thanks to its low-cost, high torque at low speed and open loop positioning capabilities. However, a closed loop control is often required for industrial applications with high precision requirements. READ MORE
