    Keywords : BLDC; brushless dc generator; brushless dc motor; JFET; Torque; Generator Torque; Automatic Torque Control; Field Effect Transistor; PWM;

    Abstract : This work was carried out on behalf of Science Safari. Science Safari wants to create a product that facilitates the understanding of how much physical work is required to create electrical energy. This is done by cranking the pedals of a bicycle. READ MORE

  4. 3. Braking with a Directional Control Valve in a Hydraulic Open-Loop Transmission

    University essay from Linköpings universitet/Fluida och mekatroniska system

    Author : Jonathan Karlborg; Emil Sten; [2021]
    Keywords : Directional Control Valve DCV ; Open-loop Hydraulic Transmission; Brake function;

    Abstract : This project presents an investigation if natural braking characteristics could be achieved on an open-loop hydraulic transmission without a brake valve. The goal with the simplified system was to utilize the directional control valve to achieve similar functionality as the brake valve does in the conventional system. READ MORE

  5. 4. Torque Ripple Analysis and Compensation of Servo Drives for Robot Application

    University essay from Lunds universitet/Industriell elektroteknik och automation

    Author : August Millqvist; [2021]
    Keywords : Technology and Engineering;

    Abstract : Permanent magnet synchronous motors or PMSMs are commonly used in multiple applications, both in industry and commercial use. These motors have many pros when compared to other electrical machines but do present the issue of torque ripple, especially cogging torque. READ MORE

  6. 5. Extended and Unscented Kalman Filtering for Estimating Friction and Clamping Force in Threaded Fasteners

    University essay from Uppsala universitet/Signaler och system

    Author : Mohammad Al-Barghouthi; [2021]
    Keywords : Estimation Theory; Extended Kalman Filter; EKF; Unscented Kalman Filter; UKF; Observability; Friction; Clamping Force; Tightening; Torque Controlled; Bolt; Threaded Fasteners;

    Abstract : Threaded fasteners tend to break and loosen when exposed to cyclic loads or potent temperature variations. Additionally, if the joint is held tightly to the structure, distortion will occur under thermal expansion issues. READ MORE
