Combined Motor and Power Electronics provides Energy Efficient Drives

  • Nymand, Morten (Project Manager)

    Project Details


    It is generally accepted that at power levels below approx. 10 kW, permanent magnet (PM) motors will exhibit considerable larger efficiencies than traditional asynchronioues motors. Thus by performing a combined optimization of motor- and powerelectronics it is possible to design a significantly more efficient drive system. To become widely spread and thereby maximizing the energy savings, such a system should be designed for mass-production and preferable be modular in order to become price competitive.
    The goal of the project is to optain significant energy savings through the integration of motor and power electronics.The project will concentrate on the study and demonstration of modules for a 1-2 kW drive system. The project content includes: Definition of system requirements. Study and definition of system concept and module. Study of principles for sensorless control of PM-motors. Study and demonstration of suitable power factor controller principles. Design and development of inverter stages. Test and optimization of a complete drive system.
