摘要（英）：

The invention provides a servomotor controller (1) for reducing power peak. The servomotor controller (1) includes a first converter circuit (11) that perform conversion between AC power on a side of an AC power supply (3) and DC power on a DC side; a first inverter circuit (12) that performs conversion between the DC power on the DC side of the first converter circuit and AC power on the side of a first motor (2A); a second converter circuit (13) that performs conversion between the AC power on the side of the AC power supply and DC power on a DC side; a second inverter circuit (14) that performs power conversion between the DC power on the DC side of the second converter circuit and AC power on the side of a second motor (2B); and a power calculation unit (15) that calculates an amount of power of the first motor, wherein control is performed so that the regenerative power of the first motor is supplied to the second motor through the power supply and the regenerative power of the second motor is supplied to the first motor through the power supply, on the basis of the amount of power.
