How it Works

Speed reduction technology is heavily relied on in the Robotics, Aerospace, and Medical Equipment industries. Industry standard speed reducers require a special metal alloy, expensive high precision machining, and must be replaced about one time every two years when run on 18 hour shifts.  The short life span of a speed reducer results in a loss of productivity, which can prove very costly to a company.

Circular Wave Drive will enable a full product line of low-cost, compact, highly-efficient, ruggedized, speed-reducing gearing systems which overcome the limitations of both the Harmonic Gear Drive and Nabtesco RV, enabling the CWD to disrupt both the value and premium markets.


Compact size, high precision, low backlash, and manufactured from solid steel leading to a longer life-cycle of the speed reducer as well as low-cost in both materials and fabrication.
