    摘要: An electric motor control device is provided that controls an electric motor for driving a movable part of a machine through a transfer mechanism. When receiving a torque command as an operation command signal (9), a servo device (3) supplies an electric motor (5) with an input torque signal (12) corresponding to the operation command signal (9) to drive an electric motor (5). Consequently a movable part (7) operates to produce vibrations. The servo device (3) produces an input torque signal (12) equivalent to an input torque signal (11), and stores it together with a rotational speed signal (10) in a memory (2). An analyzer (1) carries out frequency analysis of the input torque signal (11) and the rotational speed signal (10) using FFT, and outputs the results of analysis (14).

    摘要: A three-phase/two-phase converter (10) detects the two-phase component of a three-phase stator current and performs the gamma - delta coordinate system transformation of the stator current to derive a gamma -axis current and a delta -axis current. The gamma -axis current and the delta -axis current are inputted, along with voltage designating values from a gamma -axis current controller (2) and a delta -axis current controller (3), to a stator current/induced electromotive force estimation unit (9) in order to determine an estimated value of the stator current in the gamma - delta coordinate system and an estimated value of the induced electromotive force.

    摘要: It is an object of the invention to provide a method which can detect a magnetic pole position easily and surely by using high-frequency currents such as harmonics of an inverter output and carrier frequency components. In the invention, an arbitrary high frequency other than an output frequency of a voltage source PWM inverter is generated in input voltages or currents of a motor by means (6) for producing an arbitrary phase difference between respective two phases such as UV, VW, or WU in the inverter (7), the voltages or currents are converted to a two-phase stationary coordinate system in which U-phase of the motor is alpha -axis and an axis intersecting the axis at 90 deg. is beta -axis, a current of the arbitrary high-frequency component is detected in each of the alpha - and beta -axes, the voltages or currents are converted to a two-phase stationary coordinate system in which a phase is shifted by 45 deg. from the two-phase stationary coordinate system, or in which an axis that is shifted by 45 deg. from the alpha -axis is alpha '-axis and an axis intersecting the axis at 90 deg. is beta '-axis, a current of the arbitrary high-frequency component is detected in each of the alpha '- and beta '-axes, and a magnetic pole position of the motor is detected (12) by using the high-frequency current components that are detected respectively in the four axes.

    摘要: A method for measuring the motor constant of the vector controller for an induction motor. The voltage output phase theta v has an arbitrary preset value and when a current is fed, a current command is inputted in a state where a proportional integration controller is effective and a vector controller is operated. After a motor is operated for a predetermined time, thhe gain of the proportional integration controller is brought to zero and then a voltage command value and a current detection value are measured in a state where the voltage command value is fixed by keeping the integrated value at a constant level. Subsequently, k is measured for currents of two magnitudes and a primary resistance (or line resistance) is determined from the slope.
