Title:
OPERATING METHOD OF SYNCHRONOUS MACHINE
Document Type and Number:
Japanese Patent JP2016226270
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an operating method of a synchronous machine for computing a D-axis current and a Q-axis current for operating the synchronous machine in MTPA (Maximum Torque Per Ampere), CLVL and MTPV operation modes.SOLUTION: The operating method of the synchronous machine includes: generating an MTPA curve based on a current limiting circle depending on a rated current of an inverter or a motor and a torque curve depending on a torque command; generating a voltage limiting ellipse based on a DC link voltage; displaying, on an X-Y plane, the current limiting circle, the torque curve, the MTPA curve and the voltage limiting ellipse; and computing a D-axis current and a Q-axis current based on an intersection point between at least two or more of the current limiting circle, the torque curve, the MTPA curve and the voltage limiting ellipse, displayed on the X-Y plane.SELECTED DRAWING: Figure 1
