Abstract: <P>PROBLEM TO BE SOLVED: To provide a motor controller which can detect abnormality accurately while effectively suppressing the occurrence of torque ripple at two-phase drive accompanying the occurrence of an energization failure phase.  <P>SOLUTION: A microcomputer detects the abnormality of a control system, based on the comparison between a q-axis current deviation ΔIq and a specified threshold I1.

Then, the microcomputer does not perform the judgment processing for detecting the abnormality of the control system, on the basis of the above q-axis current deviation ΔIq, in case that it is within a rotational angle range (a current limitation range) where the d-axis current command is limited within a specified range, at the occurrence of energization failure.  <P>COPYRIGHT: (C)2009,JPO&INPIT
