The present invention provides an automatic tool changer which employs a servo motor as a drive source for a tool magazine and, yet, features a minimized power consumption and a reduced steady torque of the servo motor. The automatic tool changer is adapted to perform a tool magazine indexing operation in accordance with an indexing command and then perform a tool changing operation in accordance with a tool changing command. If the next indexing command is not outputted within a predetermined time period after completion of the tool changing operation, power supply to the servo motor for driving the tool magazine is temporarily stopped and, when the next indexing command is outputted, the power supply to the servo motor is resumed for performing the indexing operation. If the next tool changing command is not outputted within the predetermined time period after completion of the tool magazine indexing operation, the power supply to the servo motor is temporarily stopped and, when the next tool changing command is outputted, the power supply to the servo motor is resumed for performing the tool changing operation.
