The Zomeworks tracker doesn't have a motor :

Introduction — Zomeworks Passive Solar Products

UNIVERSAL TRACK RACK Passive Solar Tracker for Photovoltaic Modules
Incorporating over two decades of experience with tracker design and more than three decades of innovation of new products, Zomeworks has introduced the F-Series Track Rack Passive Solar Tracker to our line of UTR Universal Trackers. This tracker is our most popular design. It features an integral early morning rapid return system, is shipped partially assembled, is easy to install, and is module specific.

Simplicity and Elegance
The sun's heat moves liquid from side to side, allowing gravity to turn the Track Rack and follow the sun – no motors, no gears and no controls to fail.

But I agree that a tracker has a much greater cost, so the much longer payback makes it hard to justify.
