Abstract
A portable electric nailing gun operating from a power source. The motor accelerates a flywheel which at the appropriate energy state is coupled through a mechanism to an anvil acting directly on the nail. The motor accelerates a flywheel that is then clutched to the output anvil causing the nail to be driven. The position of the output anvil is sensed and once the nail is driven, the motor is dynamically braked reducing the excess energy in the flywheel. This method uses a highly responsive motor and power source which enables the motor to come up to speed, drive the nail and return to a low energy condition in less than 2 seconds. The electrical control circuit and brake allow precise control and improve safety. The power source is preferably a rechargeable low impedance battery.
