This fan has driven by a tiny DC motor, which includes a high ratio gearbox. A 3v power supply or two-AA battery pack can drive it.
The mechanism is a classic rotary to linear design, modified to oscillate the fan back and forth around a pivot point.
The optional handle needs to be glued to the base.
The DC motor is from Amazon, Micro DC motor, gear speed reduction to 200 rpm, metal gears. $6.99 (6/2025)
