A motor controller includes, in a microcomputer, a voltage fall determiner determining whether a reference voltage falls from a normal value based on an Analog-to-Digital (A/D) conversion value of a second voltage from an A/D converter, and a corrector (i) calculating a correction coefficient based on the A/D conversion value of the second voltage from the A/D converter and (ii) correcting an A/D conversion value of an input voltage that is output from the A/D converter. A core of the microcomputer generates a control signal based on an input voltage A/D conversion value, when the voltage fall determiner determines that the reference voltage is equal to or higher than a normal reference value. The motor controller keeps its motor control accuracy in such manner, even when a fall of an A/D conversion reference voltage is observed.

A supercharger (12) with two separate sets of rotors (22, 24) arranged in parallel with one another is provided in an engine assembly. Both sets of rotors are used to boost air flow during high engine air flow conditions, and only one of the sets of rotors is operable to transfer torque generated by the throttling loss pressure drop as stored energy in a load device during low air flow conditions. The captured throttling losses may be electrical energy stored in a battery via a motor/generator such as during vehicle cruising.
