  2. 1. Integrated In-Wheel Motors for Low Power Traction Application

    Author : Prakashraj Kasinathan; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electric golf cart; integral-slot; force density; flux-linkage; traction motors; forklift trucks; direct-drive; electric wheelchairs power wheelchairs; low speed machines; fractional-slot;

    Abstract : This thesis is primarily concerned with the practical limits, imposed by magnetic saturation and thermal considerations, of the force density in low-speed permanent-magnet electric machines. The practical force density values obtainable in integral- and fractional-slot machines are determined. READ MORE

  4. 2. Learning Representations for Machine Activity Recognition

    Author : Kunru Chen; Thorsteinn Rögnvaldsson; Reza Akhavian; Högskolan i Halmstad; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Machine activity recognition (MAR) is an essential and effective approach for equipment productivity monitoring. Developing MAR methods for forklift trucks, a vital piece of the industry, can benefit productivity efficiency, maintenance service, product design, and potential savings. READ MORE

  5. 3. Procedure for the reduction of the effect of transient whole body vibrations

    Author : Peter Jönsson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk akustik; Engineering Acoustics;

    Abstract : There is a growing interest in the topic areas of increased vibration comfort and reduced vibration levels in work vehicles. Legislation, health costs and demands for increased competitiveness are all important motivating factors in this growing interest. READ MORE

  6. 4. Modelling level for simulation and design of fluid power systems

    Author : Jonas Nyman; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Hydraulic system modelling is a powerful tool in design work. For a complex system with many parameters it's difficult to realise the effect of a component change. Also the time to calculate this effect will be reduced with a simulation model and there will be more steps in the iterative process to optimise the system solution. READ MORE

  7. 5. A permanent magnet synchronous motor for an electric vehicle - design analysis

    Author : Yung-Kang Chin; KTH; []
    Keywords : constant power speed range; electric vehicles; field-weakening; reference flux linkage;

    Abstract : This thesis presents the study and the design analysis of apermanent magnet synchronous motor (PMSM) for the tractionapplication of an electric vehicle. An existing inductiontraction motor for an electric forklift benchmarks the expectedperformances of the proposed PMSM design. READ MORE
