Since micro mechanics gets to be more and much more essential as all products become smaller, there was a strong need of micro motors, i.e. motors into the millimeter scale. You can suspect that a millimeter sized engine just isn’t an application that is micro since the 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 having an evaluating phase so that you can characterize tiny moters with regards to their torque and energy usage and on occasion even other physical and time dependend values and properties.
Aside from the technical components and the electronics to push all elements, software program is required to make data aquisition and control. Specially, the method useful for this test work work bench make hard realtime procedure necessary, as the control over the supply voltages for brushless micromotors is synchronized up to a master moter imposing a particular rotation rate to device to be calculated by way of a coupling that is rigid. This means interrupts produced by way of a coder need to be addressed up to 80kHz to be able to production of a predefined voltage function each and every time.
An answer might be based in the time that is real operating system garantueeing a deterministic response of 4.5us at 120kHz interrupt price for the PentiumII/200. Continue reading “realtime Linux for the torque dimension phase.”
