  1. 11. Towards Sustainability Using Minimum Quantity Lubrication Technique and Nano-Cutting Fluids in Metal-Machining Processes

    University essay from KTH/Industriell produktion

    Author : Marta García Tierno; [2018]
    Keywords : Manufacturing; Machining; Turning; Minimum Quantity Lubrication; Nanoparticles.;

    Abstract : Sustainable manufacturing is making products from processes which have minimal environmental impact, energy and resource efficient, economically viable and safe for consumers and society as whole. Achieving sustainability in manufacturing would mean infusing sustainability methods on product process and system level. READ MORE

  3. 12. Kilowatt Three-phase Rotary Transformer Design for Permanent Magnet DC Motor with On-rotor Drive System

    University essay from Mittuniversitetet/Avdelningen för elektronikkonstruktion

    Author : Ye Xu; [2016]
    Keywords : contactless energy transfer; transformer power loss; iron loss; iron loss model; rotary transformer; three-phase transformer; finite element method; COMSOL Multiphysics; electrical steel; electrical steel manufacturing process;

    Abstract : The aim of this thesis is to design a kilowatt three-phase step-down rotary transformer for a permanent magnet DC motor. The permanent magnet DC motor has an on-rotor drive system, and therefore requiring a power supply that can transfer power to its drive unit without mechanical contact. READ MORE

  6. 15. A manufacture system for a self suffient lunar colony

    University essay from Institutionen för teknik, matematik och datavetenskap

    Author : Irina Westerberg; [2006]
    Keywords : Månen; Månkoloni; Självförsörjande;

    Abstract : Most of the needs for this colony of 500 persons can be supported by the moon itself. The Regolith (lunar dust) contains almost every element we need for our survival. The problem is to extract it by mining activities and the capability to store it in a proper way. Mining, manufacturing methods and power generation will be treated in this report. READ MORE
