PROBLEM TO BE SOLVED: To control regeneration power, without having to depend on controlling the performance by a controlling pattern at a regenerating period of time, when a detected value in the number of rotations in a motor exceeds a predetermined level, when the number of rotations in a three-phase motor is suddenly increased for some reason.SOLUTION: A motor-controlling circuit 1 is equipped with a battery 100, an inverter 12 to perform regeneration, and a controller 11 to control the inverter 12. In the circuit 1, the controller 11 feeds a powering time advance-angle control pattern to the inverter 12, when the three-phase motor 2 generates power at a mode over a predetermined number of rotations. |
