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 is certainly not an application that is micro given that term “micro” indicates, nonetheless it makes technical components into the micrometer scale necessary. Finally, the peformance of these systems needs to be evaluated somehow. This is exactly why the CTM, (Centre de Transfert des Microtechnique, Besancon, France) is developing a evaluating phase so that you can characterize tiny moters with regards to their torque and energy consumption as well as other physical and time dependend values and properties.
Aside from the parts that are mechanical the electronic devices to operate a vehicle all elements, application is required so as to make information aquisition and control. Specially, the strategy utilized for this test work work bench make difficult realtime procedure necessary, since the control of the supply voltages for brushless micromotors is synchronized up to a master moter imposing a particular rotation speed to unit to be calculated through a coupling that is rigid. Which means that interrupts produced by a coder need to be addressed up to 80kHz to be able to production of a predefined voltage function every time.
A remedy might be based in the time that is real operating system garantueeing a deterministic reaction of 4.5us at 120kHz interrupt rate for the PentiumII/200. In specific, a realtime module is responsible for data aquisistion taking and saving values to and from provided memory and interacting with the consumer room application in the shape of fifo buffers.
