Since micro mechanics gets to be more and much more essential as all products become smaller, there clearly was a need that is strong of engines, i.e. motors into the millimeter scale. You could suspect that the millimeter sized engine just isn’t a micro application, because the term “micro” indicates, however it makes technical components when you look at the micrometer scale necessary. Finally, the peformance of these systems needs to somehow be assessed. This is exactly why the CTM, (Centre de Transfert des Microtechnique, Besancon, France) is having a screening phase to be able to characterize tiny moters with regards to their torque and energy consumption if not other view it physical and time dependend values and properties.
Aside from the parts that are mechanical the electronic devices to operate a vehicle all elements, pc software is required to make information aquisition and control. Specially, the method employed for this test work bench make difficult real-time procedure 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 through a rigid coupling. Which means interrupts generated by way of a coder need to be addressed up to 80kHz to be able to output of a predefined voltage function every time.
An answer might be based in the time that is real running system garantueeing a deterministic response of 4.5us at 120kHz interrupt price for a PentiumII/200. Continue reading
