The present invention relates to drive controller and control method for an electric motor equipped with coil sets corresponding to plural phases. The drive controller and control method for an electric motor of the present invention control, in case of abnormal energization that a potential of the coil reaches a power supply potential or a ground potential, at least one of a high-potential side switching element and a low-potential side switching element in a failed energization system involving the abnormal energization into ON state so as to reduce a phase-to-phase impedance and also, detect a braking torque generated in the energization system involving the abnormal energization to control an output of a normal energization system not suffering from the abnormal energization based on the detected braking torque.
