realtime Linux for a torque dimension phase.

realtime Linux for a torque dimension phase.

Since micro mechanics gets to be more and much more crucial as all products become smaller, there clearly was a strong need of micro engines, i.e. motors into the millimeter scale. You could suspect that a millimeter sized engine just isn’t a micro application, because the term «micro» indicates, nonetheless it makes technical parts into the micrometer scale necessary. Finally, the peformance of these systems has got to be examined somehow. This is exactly why the CTM, (Centre de Transfert des Microtechnique, Besancon, France) is creating an assessment phase to be able to characterize tiny moters when it comes to their torque and energy usage and sometimes even other physical and dependend that is time and properties.

Aside from the technical components and the electronic devices to push all elements, pc software is required so as to make data aquisition and control. Particularly, the method useful for this test work work work bench make difficult realtime operation necessary, due to the fact control of the supply voltages for brushless micromotors is synchronized to a master moter imposing a specific rotation rate to unit to be calculated by way of a rigid coupling. Which means that interrupts produced by a coder need to be addressed up to 80kHz in order to production of a predefined voltage function every time.

An answer could possibly be based in the realtime linux running system garantueeing a deterministic reaction of 4.5us at 120kHz interrupt price for the PentiumII/200. In specific, a realtime module is in control of data aquisistion taking and saving values to and from provided memory and chatting with an individual area application in the shape of fifo buffers.
