    摘要: The present invention relates to sensorless rotor position estimation of a salient machine, such as a switched reluctance machine or a salient brushless DC machine. The invention relates to a test system (200) for a salient machine (230) to be driven using an inverter (220). Periods of zero current may occur in the phases of the salient machine. The test system (200) comprises a test pulse generator (210) for applying a voltage test pulse with the inverter of the salient machine. The voltage test pulse may be applied in an idle phase of the machine. The test system furthermore may comprise a measurement circuit (240) for determining a damped resonance response following the end of the voltage test pulse at which moment at least one terminal of a phase winding of the machine is decoupled, and a processor (250) for deriving therefrom a position of a rotor of the salient machine (230).

    摘要: A combined heat power system comprises a Rankine cycle, optionally an organic Rankine cycle, using a fluid both in gaseous phase and liquid phase. The Rankine cycle comprises - an evaporator for evaporating the fluid from liquid phase to gaseous phase, - an expander for expanding the fluid in gaseous phase provided by the evaporator. The expander is suitable to transform energy from the expansion of the fluid in gaseous phase into mechanical energy, - a condenser for condensing the fluid from gaseous phase from the expander to liquid phase and - a liquid pump for pumping the fluid in liquid phase provided by the condenser to the evaporator. The system comprises a heat source providing exhaust gas. The exhaust gas provides thermal energy for evaporating the fluid from liquid phase to gaseous phase by the evaporator. The system further comprises a generator unit for converting mechanical energy from expander to electrical energy. The expander is a volumetric expander.

    摘要: Permanent magnet synchronous machines (100) are described having good efficiency, as well as corresponding methods for making a stator (110) or stator teeth (114) for such machines. A method for fabricating a stator (110) for an axial flux permanent magnet synchronous machine is for example described comprising obtaining several sets of substantially identical laminates (302), and stacking the sets of substantially identical laminates (302) so that a subsequent laminate has a part overlapping (304) the previous laminate and a part not overlapping (306) the previous laminate. Alternatively, a method of manufacturing a stator (110) is described wherein the method comprises obtaining a set of laminates (302) connected to each other with a thin strip (402) of material and creating a stack by folding the laminates (302) along the thin strip (402) of material. The stator teeth (114) can furthermore be fabricated such that the air gap (602) that is formed between the stator tooth and the permanent magnets changes along the radial direction.
