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

    Författare :Prakashraj Kasinathan; Chalmers University of Technology; []
    Nyckelord :electric golf cart; integral-slot; force density; flux-linkage; traction motors; forklift trucks; direct-drive; electric wheelchairs power wheelchairs; low speed machines; fractional-slot;

    Sammanfattning : 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. LÄS MER

  3. 2. On Drive Force Distribution and Road Vehicle Handling - A Study of Understeer and Lateral Grip

    Författare :Matthijs Klomp; Chalmers University of Technology; []
    Nyckelord :drive force distribution; drive force; vehicle handling; lateral grip; understeer; acceleration; steady-state cornering; vehicle dynamics; combined slip;

    Sammanfattning : Computer controlled vehicle sub-systems aimed to support drivers in various drivingsituations are rapidly increasing in number and sophistication. These systemshave evolved from anti-lock braking and traction control systems, to electronic stabilitycontrol. LÄS MER

  5. 4. An Interactive Traction Motors Design and Selection Software

    Författare :Hasan El Hinaoui-Hamze; Chalmers University of Technology; []
    Nyckelord :CAD; Access; Electric Drives; Visual Basic; Internal Combustion Engines ICEs ; · Electric Motors EMs ; SQL; MATLAB; Hybrid Electric Vehicles HEVs ; Traction Motors; MagNet;

    Sammanfattning : Use of electric motors in vehicle traction, in fact, predates the internal combustion engines (ICEs). Electric vehicles powered by dc motors were known as far back as 1890. Compared with vehicles powered by ICEs, the main drawback of the early electric vehicles was, and still is, their limited range and long recharging time. LÄS MER
