ABSTRACT:
A tool with a driver, which is translatable along a driver axis, and a motor assembly having an electric motor, a flywheel, a roller and an actuator. The electric motor is selectively operable for driving the flywheel. The actuator is selectively operable for translating the roller such that the roller drives the driver against the flywheel to permit energy to be transmitted from the flywheel to the driver. The electric motor is selected to substantially minimize energy losses associated with bringing a mechanical inertial of the motor assembly to a predetermined rotational speed while substantially minimizing an amount of time that is needed to bring the mechanical inertia to the predetermined rotational speed.
