For Immediate Release






CAMARILLO, CALIFORNIA and VENTURA, CALIFORNIA – April 25, 2006 – ThinGap Corporation, the leader in high power density DC motors, and Rocketstar Robotics, an innovator in the design and manufacturer of actuators for spaceflight applications, today announced an agreement providing Rocketstar Robotics with an exclusive license for marketing ThinGap’s coreless motor technology for use in spaceflight applications. 


“ThinGap’s high power density motor coil technology allow longer battery life for spaceflight applications, which will provide Rocketstar Robotics with a substantial competitive advantage for the motion control needs of spacecraft mechanisms,” said Rean Pretorius, president & CEO, ThinGap Corporation.  “This agreement jumpstarts ThinGap’s efforts to broaden its market base by penetrating the growing market for high power density motors in spacecraft applications with a newer technology that provides clear advantages over mature motor technologies.”


“The ThinGap technology provides us with the substantial advantages of zero cogging, high efficiency and low mass when compared with other technologies for the spaceflight market,” said Douglas Petercsak, president, Rocketstar Robotics.  “Once our customers complete their evaluations we fully expect Rocketstar Robotics motors incorporating ThinGap technology to takeover a significant share of the spacecraft motor market.”


The ThinGap technology eliminates magnet wire and iron laminations in the stator while incorporating a rotor containing the entire magnetic circuit as it rotates.  This eliminates lamination power loss caused by hysteresis.  In combination with high-energy neodymium-iron-boron magnets, the thin wall of the stator coil allows a miniature air gap, which creates a high power density motor, with excellent characteristics for low power applications.


ThinGap motors are used in applications requiring high power density such as portable battery systems, medical devices, industrial hand-held power tools and unmanned vehicles, as well as wind-generated energy applications.


Other benefits of the ThinGap technology include zero cogging torque which is invaluable for low ripple torque pointing applications and a near perfect sinusoidal back EMF that allows for precision motion control.  Rocketstar Robotics motors, based on the ThinGap technology, will be designed from the ground up as spaceflight actuation systems.
