| 发明名称 | Control method for a power tool and a power tool | ||
| 摘要 | A control method for a power tool and a power tool is disclosed. The control method has an operating mode and a safety mode. In the operating mode, a motor drives a tool receptacle in a rotating manner. In the operating mode, the motor has a power consumption in the amount of at least an operating value. The safety mode is triggered if a sensor device detects a rotational blockade of the tool receptacle. In the safety mode, a clutch that is switchable by electrical signals located in the drive train between the motor and tool receptacle is periodically opened and closed and a power consumption of the motor is reduced as compared to the operating value. | ||

| 主权项 | 1. A control method for a power tool, comprising the steps of: driving a tool receptacle by a motor in a rotating manner around a working axis in an operating mode, wherein a power consumption of the motor has an operating value in the operating mode; and triggering a safety mode when a safety device detects a rotational blockade of the tool receptacle; wherein the safety mode further comprises the steps of: periodically varying a torque of a clutch that is arranged in a drive train between the motor and the tool receptacle; and reducing the power consumption of the motor in comparison to the operating value. | ||
