<P>PROBLEM TO BE SOLVED: To properly control the output of a motor even in case abnormality occurs in a sensor which detects the position of a phase. <P>SOLUTION: A motor controller 100a is equipped with: a motor 1 consisting of an outer rotor and an inner rotor changing each other's relative phase; a phase changing means which changes the relative phase; a relative phase position sensor 84 which detects the relative phase position concerned with the relative phase, and an abnormality determination control unit 67 which sets the relative phase to either the maximum value or the minimum value (in short, the strongest phase or the weakest phase) in the phase variable range by the phase changing means, according to the number of revolutions NM of the motor 1 at abnormality of the phase position sensor 84. <P>COPYRIGHT: (C)2009,JPO&INPIT |
