The gearbox comprises a motor, a motor shaft, a drive-outlet, and the installation of one-way bearings in suitable places in the gear-train. The drive-outlet can be driven at two different speeds in the same rotational direction.

When operating in the lo-speed mode, the drive-outlet is driven via the gear-train, with a resulting increase in torque. This gearbox is simple to construct, and operable without expensive control electronics. In particular applications with electronic motor speed and directional control, a much broader and useable drive-outlet speed range is achieved.
