La tesi si occupa della scelta corretta di un motore elettrico brushless e relativa trasmissione. La scelta è basata su curve JM-Mm, rms e JM-Mm, max , che vengono ottenute dalla "missione di riferimento", per data trasmissione. Il metodo permette al progettista di collegare il motore elettrico con la trasmissione al fine di garantire il campo di lavoro dinamico del motore . E il campo di lavoro servizio continuo adeguati alla macchina operatrice. In particolare, la ricerca tiene in conto i rendimenti diretto e inverso della trasmissione e la sua inerzia. Inoltre, saranno analizzati le espressioni analitiche e le figure, con l'aiuto delle quali la scelta dei motori elettrici sarà effettuata. Infine, un algoritmo si propone di elaborare la scelta corretta del motore elettrico. L'algoritmo è basato su considerazioni analitiche ed è stato sviluppato per ridurre al minimo il tempo di calcolo.

Abstract
The thesis deals with the proper choice of brushless electrical motor and transmission. The choice is based on JM-Mm,rms and JM-Mm,max curves, that are obtained from the “reference task” for giving transmission. The method permits the designer to link the electrical motor with transmission in order to guarantee that the motor’s dynamic working range and continuous duty working range is suitable for the driven load. Particularly, the thesis takes into account the direct and inverse efficiencies of the transmission and its inertia. In addition, the analytic expressions and figures, with the help of which the choices of electrical motors will be achieved, will be analyzed. Finally, an algorithm is proposed to elaborate the choice of the proper electrical motor. The algorithm is based upon analytical considerations and has been developed to minimize its calculation time.File | Dimensione | Formato | |
