Abstract
Description
Die Erfindung bezeichnet eine netzgespeiste Elektrohandwerkzeugmaschine mit einer Leistungselektronik für einen Elektromotor, insbesondere eine Elektrohandwerkzeugmaschine für das Baugewerbe.The Invention refers to a mains powered power hand tool with power electronics for an electric motor, in particular an electric hand tool machine for the Construction industry.
Für leistungsfähige netzgespeiste Elektrohandwerkzeugmaschinen werden Elektromotoren verwendet, deren Motorsteuerung einen Gleichspannungszwischenkreis mit einem Zwischenkreiskondensator aufweist, der optional von einer Leistungselektronik regenerativ gespeist wird. Insbesondere im Baugewerbe treten bedingt durch länderspezifische Standards, verlustbehafteten Verlängerungsleitungen und schwacher bzw. defekter lokaler Stromversorgungen sehr grosse Schwankungen der verfügbaren Netzspannung auf, an welcher die Elektrohandwerkzeugmaschinen dennoch zuverlässig die volle Leistung abgeben müssen. So wird der durch Normen bestimmte Betriebsbereich der Netzspannung von 85 bis 256 Volt bei 50 bzw. 60 Hz im rauhen Baugewerbe oft verlassen, bspw. in Japan mit realen Spannungen unter 85 Volt oder in Westeuropa/Amerika bei fehlerhaften Baustellenverteilern im 230 Volt Drehstromnetz, welche die 400 Volt Dreieckspannung liefern.For powerful mains powered Electric hand tool machines are used electric motors whose Motor control a DC voltage intermediate circuit with a DC link capacitor which optionally has a power electronics regenerative is fed. Especially in the construction industry, due to country-specific standards, lossy extension lines and weak or defective local power supplies very large Fluctuations in the available Mains voltage on which the electric hand tool machines nevertheless reliable have to give full power. Thus, the operating range of the mains voltage determined by standards becomes 85 to 256 volts at 50 or 60 Hz often left in rough construction, For example, in Japan with real voltages below 85 volts or in Western Europe / America with faulty construction site distributors in the 230 volt three-phase network, which provide the 400 volt triangle voltage.
