Definitions for "DIRECT DRIVE"
With a direct drive tool, all power from the motor is transferred directly to the output shaft.
A motor system in which rotational energy is transferred directly to the drive source without the use of a pulley belt or idler wheel.
The inertial fusion target is directly driven by energy from the fusion driver. That is the power from the driver couples directly to the surface of the fuel capsule. Although more efficient, this form of target coupling requires very precise beam aiming and uniform target illumination.
A condition where the transmission connects the engine to the differential directly without altering the gear ratio.
