PROBLEM TO BE SOLVED: To provide a motor driving system which can be suitably controlled in response to the voltage of a DC line. SOLUTION: The motor driving system comprises a commercial power source 1, a first power converter 3 for converting the power output from the commercial power source 1 into a DC power to output the DC power to a DC line, a motor 5 electrically connected to the line 4 and driven by the power supplied from the line 4, a motor driver 6 disposed between the line 4 and the motor 5 to control the drive of the motor 5, an electric storage means 7 electrically connected to the line 4 to discharge the power to the line 4 at the time of discharging and to charge the means 7 by the power of the line 4 at the time of charging, and a control means 9 for detecting the voltage of the line 4 to control charging/discharging of the means 7 based on the detected result. |
