La storia degli azionamenti per cancelli automatici è cambiata quando l'adozione delle automazioni elettromeccaniche hanno sostituito gli azionamenti oleodinamici meno efficienti e non standardizzabili. Un altro cambiamento è in corso proprio ora. Sulla base della loro elevata efficienza e densità di potenza, i motori brushless costituiscono una buona alternativa ai vecchi motori a spazzole o asincroni. L'adozione di motori sincroni a magneti permanenti (PMSM) è in aumento e molte aziende li stanno implementando in applicazioni medie, come l'azionamenti dei cancelli. Nonostante la loro alta efficienza sono spesso controllati con circuiti aperti o con metodi di controllo scalari che non utilizzano appieno la tecnologia. Per sfruttare la densità di potenza del motore deve essere considerata una tecnica di controllo vettoriale che produce la massima coppia in ogni istante. Il controllo ad orientato di campo (FOC) viene quindi implementato in firmware e la sua applicazione è stata assistita con metodi basati su modello e tramite la libreria di controllo motore di STMicroelectronics.

Abstract
The history of automatic gate drives changed when the adoption of electromechanical automations have substituted the less efficient and not standardizable oleodynamic drives. Another change is underway right now. Based on their high efficiency and density power brushless motors constitute a good alternative to the older brushed or asynchronous motors. The adoption of permanent magnets synchronous motor (PMSM) is increasing and many industries are implementing them in medium applications, such as gate drives. Despite their high efficiency they are often controlled with open-loops or with scalar control methods that do not take full advantage of the technology. In order to exploit the motor power density a vector control technique must be considered for produce the maximum torque at any instant. The field oriented control (FOC) is then implemented in firmware and its application has been assisted with model base methods and the motor control library of STMicroelectronics.File | Dimensione | Formato | |
