摘要： Reliability and accuracy of a sensor are secured while adjustment cost of a sensor module is suppressed. A signal component analysis part 10 receives a signal output from a signal processing part 7 before passing through a low-pass filter 8, analyzes whether or not application of a fragile frequency with respect to a physical quantity is equal to or more than a threshold level, if the application of the fragile frequency is equal to or more than the threshold level, outputs output stop signals to output signal control parts 9, 16. The output signal control parts 9, 16 receive control signals output from the signal component analysis part 10, and outputs an acceleration signal and a physical quantity signal from which noise has been removed by the low-pass filters 8, 15 through the signal processing parts 7, 14.

摘要： If magnitude relations between the output terminal voltage based on a DC negative terminal of the inverter and a threshold voltage that is a fixed value are compared, polarity thereof is changed at a predetermined rotor phase. The magnitude relation, for example, is detected by an inexpensive and simple apparatus such as a level shift circuit and a NOT circuit. The rotor phase of the permanent magnet synchronous motor is inferred on the basis of changes in the magnitude relation and if it is differentiated, a rotation speed is inferred. If the inferred values of the rotor phase and rotation speed are fed back to synchronous operation or vector control, the free-running permanent magnet synchronous motor is restarted.

摘要： In a system in which current is detected in an inexpensive manner or in a system in which a position detector is omitted, the present invention provides a high-efficiency vector controller for a permanent magnet motor that can minimize current at the same torque even when there is setting error (R−R*) in resistance. Even when a current value commanded for the d-axis is set to zero, a virtual inductance value calculated from a detected q-axis current value is used for output voltage value calculation and phase error estimation calculation; so even if there is setting error (R−R*) in resistance, current can be minimized at the same torque and thereby the present invention can provide a high-efficiency vector controller for a permanent magnet motor.
