    • A fastening tool (10) and method of operating a fastening tool (10) can include a driver (28), a motor (32), a flywheel (34) driven by the motor (28), an actuator (44), and a controller (54). The actuator (44) can cause the driver (28) to engage with the flywheel (34) to cause the driver (28) to move along an axis. The controller (54) can selectively operate the motor (32) and selectively operate the actuator (44). In a first state, the controller (54) will not operate the actuator (44) unless the contact trip switch (50) and the trigger switch (18a) are both actuated, the contact trip switch (50) being actuated prior to actuation of the trigger switch (18a), and the flywheel (34) is rotating at a first predetermined speed. When the controller (54) is in the first state, the controller (54) can operate the motor (32) to rotate the flywheel (34) at a second predetermined speed until the earlier of a second predetermined period of time after operation of the actuator (44), or a subsequent operation of the actuator (44).

    • A high inertia driver system for a fastening tool having an electric motor that drives a flywheel to contact a driver blade to drive a fastener into a workpiece. The high inertia driver system also has a return system which prevents the unintentional driving of a second fastener. The return system uses a return spring that controls the recoil energy of the driver blade after driving a fastener into a workpiece. The system achieves a long operational life for the fastening tool by increasing the number of return cycles of the driver blade free of a return spring failure.
    • 一种用于紧固工具的高惯性驱动器系统,该紧固工具具有电动机,该电动机驱动飞轮与驱动器叶片接触以将紧固件驱动到工件中。 高惯量驱动器系统还具有防止第二紧固件意外驱动的返回系统。 返回系统使用复位弹簧,该复位弹簧在将紧固件驱动到工件中之后控制驱动器刀片的反冲能量。 该系统通过增加驱动器叶片的返回循环的数量而实现紧固工具的长使用寿命,而没有返回弹簧故障。
