SELF-POWERED SERVO MOTOR SYSTEM

摘要

PROBLEM TO BE SOLVED: To simplify wiring from a control unit to multiple servo motors disposed in arbitrary positions in equipment to more efficiently operate the servo motors, and to provide a servo motor system having the functions of: charging multiple batteries for servo motors placed at various points of the equipment body from a charging terminal; charging a weak battery and driving the corresponding servo motor; and suppressing the power consumption of motors when they are not driven. SOLUTION: The servo motor system is so constructed that actuators are disposed at multiple points in the equipment. A control unit and a charging battery are installed in the center. In each actuator, a servo motor unit is installed. Each servo motor unit incorporates a battery as a motor power supply integrated with a servo motor and a motor control unit. As a preferred embodiment, the control unit in the center and each actuator are connected with each other by a line that is used both as a signal line and a supply line for charging the battery.
