<P>PROBLEM TO BE SOLVED: To reduce the rated power of a resistor for absorbing regeneration power and to reuse part of regeneration power while employing a capacitor of small capacity for absorbing regeneration power. <P>SOLUTION: A resistor circuit 16 for absorbing regeneration power absorbs regeneration power and consumes the regeneration power through a resistor for absorbing regeneration power. Furthermore, a circuit 32 to be charged with regeneration power absorbs regeneration power and stores it as charges in a capacitor 18 for absorbing regeneration power. Regeneration energy generated when a motor 20 decelerates is used simultaneously by the resistor circuit 16 for absorbing regeneration power and the circuit 32 to be charged with regeneration power in order to perform operation for absorbing regeneration power. When powering including the time when the motor accelerates, charges stored in the capacitor 18 for absorbing regeneration power is reused for driving the motor 20. <P>COPYRIGHT: (C)2009,JPO&INPIT |
