<P>PROBLEM TO BE SOLVED: To provide the controller of an electric motor which shortens the time required for the actual current to converge to a current command value when the actual current rises. <P>SOLUTION: The controller of an electric motor controls the actual current of the electric motor to converge to a current command value by controlling a voltage command value for the electric motor. The controller includes a memory which stores a threshold for the difference between the current command value and the actual current, a first limit value for the integration term of the voltage command value, and a second limit value smaller than the first limit value for the integration term, and a limiter 35 which limits the integration term based on the data in the memory. <P>COPYRIGHT: (C)2010,JPO&INPIT |
