PROBLEM TO BE SOLVED: To provide a motor current control unit controlling the waveform of a current command which is operated by digital processing with software or the like to be a waveform approximate to an ideal sine wave, and its method. SOLUTION: This motor current control unit is equipped with a speed control operating part 2 which has a current command operating part 2a operating a current command according to a speed command signal inputted as a digital signal, and outputs the current command as an analog current command, and filters 7u, 7w for current command which filter the analog current command. The speed control operating part 2 contains a phase compensation part compensating phase delay of the current command which is caused by filtering. |
