  1. 1. Development of Test Methodology for Electromechanical Linear Actuators

    University essay from Uppsala universitet/Signaler och system

    Author : Isak Linder; [2022]
    Keywords : Electromechanical; linear actuator; test methodology; test rig; rack and pinion; transport delay; latency; spring mass damper; load cell; load force; load unit; test unit; DUT; PID; PID control; control mechanics; cogging torque; torque; flex; stiffness; current saturation; torque control;

    Abstract : This master thesis aims to develop a test methodology for electromechanical linear actuators. A linear actuator acts as a linear motor, converting a power source to linear motion. The electromechanical linear actuator in this project has an electric motor as its power source and uses a rack and pinion system to transfer that power to linear motion. READ MORE

  3. 2. 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

  4. 3. Design and Simulation of a Slotless Aircored PM Synchronous Generator

    University essay from Uppsala universitet/Institutionen för elektroteknik

    Author : Bakhtiyar Asef Hasnain; Ademir Hodzic; [2020]
    Keywords : Slotless; Aircored; PM; Permanent Magnet; PMSG; Permanent Magnet Synchronous Generator; SPMSG; COMSOL; FEMM; FEM; Solidworks; Fusion 360; Axial Flux Generator;

    Abstract : This thesis is a study on an unconventional slow speed direct drive permanent magnet (PM) generator. Unlike a standard permanent magnet synchronous generator (PMSG) which has the copper coils wound around iron teeth, the work in this thesis will present a generator where the copper coils are directly mounted on the stator which eliminates the slots and teeth in the generator.

  5. 4. Steering system development using test rig and driving simulators

    University essay from KTH/Fordonsdynamik

    Author : Utsav Khan; Andrea Bianchi; [2019]
    Keywords : ;

    Abstract : Conventional model-based development approaches such as Model-in-Loop (MiL) and Software-in-Loop (SiL) have been used in electric power assisted steering (EPAS) development in recent years, but when it involves a physical motor and the vehicle communication network, the development mostly comes down to real vehicle testing and tuning. The objective and outcome of this master thesis is to develop a Hardware-in-Loop (HiL) environment that involves the real EPAS powerpack and human Driver-in-Loop (DiL) using a static driving simulator.
