Headquartered in suburban Baltimore, Maryland, USA, DDMotion has invented the world’s first mechanical, infinitely-variable motion controls. Our revolutionary technology’s core element is the patented three-variable Transgear™ gear assembly. The Transgear assembly provides the optimal gear ratio for all operating conditions, resulting in a cost efficient, environmentally friendly method of controlling machinery. The company holds an array of patents on its innovative variable motion controls.
DDMotion offers a breakthrough paradigm in the development of turbines used to produce electricity. Companies who use existing technologies are only able to incrementally improve on their efficiency and performance. Focusing on a new logic for motion control rather than enhancements to existing products, DDMotion offers its partners a competitive advantage that can help them increase energy production and position themselves as leaders in the industry.
