<P>PROBLEM TO BE SOLVED: To provide a motor driving system which can decelerate the driving of a load while consuming regenerative power with braking resistance, and in which there is no need to insulate the braking resistance at high voltage. <P>SOLUTION: The motor driving system is constituted of an inverter device 10 having an inverter decelerating means 9, an AC motor 5 driven by the inverter device 10, a breaking means 6 connected to an output side of the inverter device 10 and having a transformer 61 at an input part. The inverter decelerating means 9 reduces the output frequency of the inverter device 4 so that the AC motor 5 is excited and the regenerative power of the AC motor 5 is supplied to the braking means 6 when the AC motor 5 is decelerated. <P>COPYRIGHT: (C)2009,JPO&INPIT |
