چکیده | ||
ریزالور حسگری است که برای تعیین موقعیت گردان یا خطی مورد استفاده قرار میگیرد. طراحی بهینه این حسگر، نیازمند یک مدل دقیق و درعینحال سریع است. چنین مدلی برای ریزالور خطی، باید قابلیت در نظر گرفتن اثر انتهایی را هم داشته باشد. لذا، در این مقاله یک مدل تحلیلی بر اساس روش زیرناحیه برای ریزالور خطی ارائه میشود. این مدل نهتنها اثر انتهایی طولی بخش متحرک و ساکن را به خوبی در نظر میگیرد؛ بلکه اثر دندانه و شیاردار بودن این دو بخش را نیز مورد توجه قرار میدهد. نتایج مدل ارائهشده، با نتایج روش اجزای محدود و نتایج آزمایش عملی روی نمونه ساختهشده حسگر، مورد ارزیابی و تایید قرار میگیرد. | ||

چکیده [English] | ||
A resolver is a position sensor used for rotational or linear positioning. The optimal design of the resolver needs an accurate and computationally fast model. Such a model for the linear resolver must also be able to take the longitudinal end effect into account. Therefore, in this paper, an analytical model based on the subdomain method is proposed for the linear resolver. The presented model, not only considers the longitudinal end effect of the stator and mover, but also takes the cores’ slotting effect into account. The results of the proposed model are verified by comparing them with the results of the finite element analysis and the experimental measurements on the sensor’s prototype. | ||
