<P>PROBLEM TO BE SOLVED: To provide a motor controller which can control a motor to generate a larger torque even during saturation, and to provide a motor control method. <P>SOLUTION: The motor controller 20 for controlling the drive current of a motor by determining the current values id and iq of d and q phases through dq conversion for converting into the dq rectangular coordinates and performing current loop processing of d and q phases is provided with a means 25 for controlling the vector angle θv of the composition vector of voltage command values Vd and Vq of d and q phases for the q axis. Consequently, a larger torque can be generated from the motor even during saturation. <P>COPYRIGHT: (C)2008,JPO&INPIT |
