<P>PROBLEM TO BE SOLVED: To limit regenerated power without recourse to the control by a control pattern at regeneration when the revolution-detected-value of a motor is over a specified value in case that the number of revolutions of the three-phase motor increases by any reason. <P>SOLUTION: In a motor control circuit 1 which is equipped with a battery 100, an inverter 12 to perform regenerative operation, and a controller 11 to control the inverter 12, the controller 11 sends out a spark advance control pattern at power running to the inverter 12 when the three-phase motor 2 generates power, over the specified number of revolutions. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
