摘要： A locking device of a rotary shaft includes a clutch member rotating integrally with the rotary shaft and provided so as to be displaceable in the direction of axis of the rotary shaft, a locking member provided in a fixed state to engage the clutch member to regulate the rotation of the clutch member, a biasing member biasing the clutch member toward the locking member, and a torque transmission member rotating under the rotary torque transmitted thereto from a power source, having a boss loosely inserted into a cam groove provided in an outer peripheral portion of the clutch member, and transmitting the rotary torque to the clutch member via the boss. The boss is displaced within the cam groove with switching of the rotation/stop of the torque transmission member or switching of the rotational direction thereof.

摘要： A rotary shaft locking device includes a locking unit having a transmission gear receiving rotary torque from a power source, transmitting rotary torque to a rotary shaft as the transmission gear receives rotary torque from the power source, and locking the rotary shaft as transmission of rotary torque from the power source is cut off, and a first planetary gear and a second planetary gear provided to be meshed with a sun gear and to planetarily move around the sun gear, and displaced between a meshed position and an unmeshed position so as to be meshed with and separated from the transmission gear. The locking unit locks the rotary shaft for a power cutoff time which occurs when the rotation direction of the sun gear is switched and for which the transmission gear is not meshed with both the first planetary gear and the second planetary gear.

摘要： If a bus current a bus current detector 11 detects exceeds a current cutoff value, an overcurrent detector 12 supplies a gate driver 14 with an open signal for turning off switching elements 5-10 to break the current to a motor 1. Besides, when the overcurrent detector 12 detects an overcurrent, a feedback controller 15 provides the gate driver 14 with a short-circuit braking instruction to apply short-circuit braking after breaking the power supply, and to restart PWM control from a state in which the short-circuit braking is being applied and the duty ratio command value is reset at 0.
摘要翻译：如果总线电流检测器11检测到的总线电流超过电流截止值，则过电流检测器12为栅极驱动器14提供用于断开开关元件5-10的断开信号，以断开电动机1的电流。此外，当过电流检测器12检测过电流，反馈控制器15为栅极驱动器14提供短路制动指令，以在断开电源之后施加短路制动，并从短路制动状态重新启动PWM控制并且占空比指令值被重置为0。
