A portable electric nailing gun operating from a power supply. 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 actuation is governed by a control circuit and initiated from a trigger switch. The stored energy delivered from the motor is coupled to the output anvil drives the nail. At least one position of the output anvil is sensed and once the nail is driven, the power is disconnected from the motor. This method uses a direct acting clutch and a harmonic motion nailing mechanism to reduce wear and increase robustness of the nailer. Elastic elements are used to limit stresses during the impact periods. The electrical control circuit and sensors allow precise control and improve safety. The power supply is preferably a rechargeable low impedance battery pack.
