发明名称 CIRCUIT ARRANGEMENT FOR DETERMINING AND CORRECTING THE PHASE CURRENT SET VALUES IN SYNCHRONOUS MOTORS
摘要 System for assigning and correcting signals of the synchronous motor set phase current values containing corrective proportional amplifiers; is characterised in that it has two input circuits (WES, WEC) connected respectively with first inputs of the first and second multiplication element (1,2), whose second inputs are coupled and constitute the system input (WEM), while the output of the multiplication element (1) is connected with first input of the first proportional corrective amplifier (3) and first input of the first and second adder (5,6), while the multiplication element output (2) is connected with the second input of the first adder (5) and with input inverter (4), while the inverter's output is connected with the second input of the second adder (6) and the adders' outputs (5,6) are connected respectively with the first inputs of the second and third correctional amplifier (7,8), whereas second inputs of the first, second and third correctional amplifier (3,7,8) are connected with the output of the comparing element (9), while their outputs are connected with the respective outputs (WYIR, WYIS, WYIT) of the system and with three inputs of the comparing element (9), the additional input of the comparing element receives designated reference voltage (Uod).<IMAGE>
