PROBLEM TO BE SOLVED: To provide a motor drive circuit which can efficiently accumulate regenerative energy. SOLUTION: This motor drive circuit has a rectifying capacitor (7), provided between motor drive lines (3 and 4) and a regenerative energy-accumulating capacitor (10), in which an electrostatic energy is accumulated only in a regenerative operation state of a motor and which is connected, in parallel with the motor drive line (3) having a high potential in the regenerative operation state of the motor. |
