Flat motor for shape shifters. (Design News).(low-cost, high-torque rotary motor, based on 'smart' materials developed at Penn State)
Engineers from Penn State University have developed a low-cost, high-torque rotary motor, based on 'smart' materials, that can be configured in a wide range of formats, including one as flat and thin as a CD case.
The inventors say that, in the flat format, the motor could be used to drive changes in the camber of airplane wings or fins, essentially shape-shifting the curvature of the wing or fin surface.
In other formats, the motor could work in tightly integrated spaces where other motors can't fit. It could, for example, serve as the drive element in thinner, lighter, laptop computers or other compact, portable consumer products or in manufacturing equipment that processes things by moving or shaking them.
The project's leader, Proffessor Gary Koopmann says that the flat motor has a starting torque advantage over conventional electric motors since speed is not required for high torque output. The prototype flat motor has reached a free speed of 760 rpm and a maximum torque of 0.4 Nm.
