Title:
ACTUATOR AND ACTUATOR SYSTEM
Document Type and Number:
Japanese Patent JP2021044994
Kind Code:
A
Abstract:
To provide an integrated actuator in which a regenerative resistance is omitted or simplified, and an actuator system including the actuator.SOLUTION: An actuator 10 includes a motor 12, a drive circuit 11, a power supply line LP1 that connects a power supply device 20 and the drive circuit 11, a wiring L1 and a wiring L2 connecting the output terminal of the drive circuit 11 and the input terminal of the motor 12, a dynamic brake circuit 14a that short-circuits the wiring L1 and the wiring L2, and a short-circuit control unit 131 that controls the dynamic brake circuit 14a to short-circuit the wiring L1 and the wiring L2 when a voltage value of the power supply line LP1 exceeds a threshold value. The drive circuit 11 receives power from the power supply line LP1 to drive the motor 12, receives regenerative power from the motor 12, and supplies regenerative power to the power supply line LP1.SELECTED DRAWING: Figure 1
