- Description
- NASA�s Technology Transfer Program solicits inquiries from companies interested in obtaining license rights to commercialize, manufacture and market the following technology.� License rights may be issued on an exclusive or nonexclusive basis and may include specific fields of use.��NASA provides no funding in conjunction with these potential licenses. THE TECHNOLOGY: Innovators at the NASA Johnson Space Center have developed a method for controlling precise motion of a Brushless DC (BLDC) motor using relatively inexpensive components.� Precision motors are usually quite expensive and inefficient when operating at slow speeds.� This technology uses a method to control BLDC motors over a broad range of speeds, ranging from about 0.025 rpm to about 7000 rpm.� Its ability to operate at these ranges and with high precision provides an opportunity to integrate this technology to many applications and industries.� Commercial motors may employ this technology to extend their dynamic range.� This technology can also be integrated into surgical robots that require advanced precision motion control systems.� Hybrid and electrical vehicles can integrate this technology to their operating system to improve efficiencies. The Precision Low Speed Motor Controller was designed as part of an OpTIIX telescope for the International Space Station.� This technology is based on a precise current control loop and a high fidelity velocity measurement algorithm.� The precise current loop uses a mathematical model of the electrical dynamics of the motor, custom electronics, and a PI controller to maintain a rapid response and smooth current control.� The velocity measurement algorithm is embedded in the velocity loop that is wrapped around the current loop to provide a smooth low velocity control. Current motors are only capable of operating at approximately 15 rpm with a risk of excessive jitters.� This technology reduces the responsive rpms by several orders of magnitude to approximately 0.025 rpms.� This technology's capability has been integral to the success of several NASA projects, such as the OpTIIX telescope, the NASA Robonaut 2 robot , and the Modular Robotic Vehicle (MRV). To express interest in this opportunity, please submit a license application through NASA�s Automated Technology Licensing Application System (ATLAS) by visiting https://technology.nasa.gov/patent/MSC-TOPS-76 If you have any questions, please contact NASA Johnson Space Center�s Technology Transfer Office at jsc-techtran@mail.nasa.gov with the title of this Technology Transfer Opportunity as listed in this FBO notice and your preferred contact information.� For more information about licensing other NASA-developed technologies, please visit the NASA Technology Transfer Portal at https://technology.nasa.gov/ These responses are provided to members of NASA�s Technology Transfer Program for the purpose of promoting public awareness of NASA-developed technology products, and conducting preliminary market research to determine public interest in and potential for future licensing opportunities.��No follow-on procurement is expected to result from responses to this Notice.
