摘要： A speed control apparatus having a high frequency generator for superposing a high frequency signal on an estimated magnetic flux axis. A high frequency component extractor extracts an error signal of a magnetic flux position from a voltage or current detection signal having the same frequency component as a frequency component of the high frequency signal. A magnetic flux observer estimates a magnitude and a position of a magnetic flux. A first adaptive regulator adaptively regulates an error signal on a high frequency superposing side. A second adaptive regulator adaptively regulates an error signal on a magnetic flux observer side. A hybrid device switches the first adaptive regulator at a very low speed, the first and second adaptive regulators at a low speed and the second adaptive regulator at a high speed. A speed estimator estimates a speed from an output of the hybrid device.

摘要： A method of measuring a motor constant is provided in a vector control apparatus for an induction motor. A voltage output phase θv is set at a previously set arbitrary phase. Prior to applying a current, a current command is fed to operate the vector control apparatus with a proportional-plus-integral controller being set operative. After conduction for a predetermined time, the gain of the proportional-plus-integral controller is set to zero to maintain an integrated value constant and accordingly fix a voltage command value. In this state, a current command value and a detected current value are measured. This measurement is performed at two levels of current, and a primary resistance value (or a line-to-line resistance value) is derived from the slope.

摘要： A control device for an alternating current motor according to embodiments includes a current distributor and a phase estimator. The current distributor divides a torque command by using a control phase and outputs a component that contributes to a mechanical output of the motor as a δ-axis current command and a component that does not contribute to the mechanical output as a γ-axis current command. The phase estimator computes a phase at which a γ-axis component of an addition amount of the output of the current controller and a voltage drop amount of inductance of the motor becomes zero and outputs the computed phase as the control phase.

摘要： A electric motor control device is provided for controlling an electric motor which actuates a movable member of a machine through a transmitting mechanism. When a torque command is given as motion command signal (9) to servo device (3), servo device (3) sends input torque signal (12) corresponding to motion command signal (9) to electric motor (5), which is energized. Movable member (7) is thus moved, producing vibrations. Servo device (3) outputs input torque signal (11) equivalent to input torque signal (12), and input torque signal (11) and rotational speed signal (10) are stored in memory device (2). Analyzing device (1) analyzes the frequencies of input torque signal (11) and rotational speed signal (10) according to an FFT, and outputs analytical result (14).
