This paper proposes a suitability of an error voltage correction method using a disturbance observer for a speed sensor less vector control. The error voltage, correction method using the disturbance observer is used with vector control of permanent magnet synchronous machine or induction machine. However, former error correction methods using a disturbance observer are based on a polarity switching of error correction voltage by a direction of phase current. In contrast, the error voltage correction method in this paper uses only disturbance observer without the polarity switching method to correct the error voltage of an inverter. A performance of the error voltage correction method using disturbance observer for the speed sensor less control is evaluated from a magnitude of torque ripple based on the simulation results. This correction method using the disturbance observer reduces the torque ripple to about 60% that of the polarity switching method.
