Summary:PROBLEM TO BE SOLVED: To drive a motor having a pulsation synchronized with a rotation in a high efficiency. SOLUTION: The controller 100 includes an AC power supply 110 for supplying a power to a three-phase brushless motor 160, a DC current sensing circuit 210 for sensing any of the voltage value and the current value of the power, and a microprocessor 200. The microprocessor 200 stores a control value and information for correcting the control value, corrects the control value based on the information, and controls any of the voltage and the current based on the control value.
