<P>PROBLEM TO BE SOLVED: To provide a drive controller for a DC commutatorless motor which can control torque continuously even in case that abnormality occurs in a current sensor, in a drive controller for a motor. <P>SOLUTION: The drive controller for a DC commutatorless motor is provided with a current detection means which detects each phase of currents, an abnormality detection means which detects the abnormality of the current detection means, and a current value estimating means which estimates the current value of the phase where the abnormality is detected on the basis of the current value of the phase excepting the phase where the abnormality is detected by the abnormality detection means. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
