Fastener tool with continuously powered flywheel

A fastener tool that drives a fastener into a workpiece comprising:

• a housing;
• a nose assembly connected with the housing, the nose assembly having a drive channel into which the fastener to be driven into the workpiece is fed, the drive channel having a drive axis;
• a driver configured to be movable along the drive axis to engage and drive the fastener in the drive channel into the workpiece;
• a motor disposed in the housing, the motor configured to be in either its energized state or its deenergized state;
• a power supply;
• a flywheel disposed in the housing, the flywheel configured to be driven by the motor and configured to transmit energy to the driver to cause the driver to move along the drive axis;
• an actuator configured to move the driver into engagement with the flywheel such that energy is transferred from the flywheel to the driver;
• and
• a controller having one or more processors, the controller operatively connected to the motor and the actuator to implement a firing sequence for driving the fastener in the drive channel into the workpiece,
• wherein the controller is configured to:
• i) control the actuator to initiate an engagement between the driver and the flywheel, and
• ii) control the motor to remain in its energized state while the flywheel is in the engagement with the driver to cause the movement of the driver along the drive axis,
• wherein the motor is controlled to be energized so that current draw from the power supply in a subsequent drive cycle does not reach zero.
