Linear electrical motors are electrical machines which directly convert electrical energy into linear motion without requiring any extra mechanical components. So far, DC and AC linear motors have been employed in many positioning systems. On the other hand, the main reasons of DC linear motors have not been widespread are their stroke limitations and high cost. This paper presents for mechatronic systems a geometric and magnetic design of single-sided, linear brushless direct current motor (LBLDC). The designed motor has 3 A, 24 V, 72 W, and 70 N pull force, high force/volume rated and low cost. Its characteristics were analyzed by using finite-element software. The prototype was simulated and released of a single-sided LBLDC. The obtained results were compared with the results obtained by the analytical methods.
S ingle phase induction motors (SPIMs) nowadays are widely used in domestic and commercial areas because of cheap cost, simple structure, low noise and small dimensions etc. Split phase, start and run-capacitor single phase induction motors are well known SPIM motor types [1]. Although a lot of advantages have mentioned, a SPIM has some disadvantages. Its efficiency is low and starting performance is not so good to compare the other electrical machines types.The optimal design of an induction motor in terms of electromagnetic torque means starting and breakdown torques are higher value [2]. Many researchers have investigated to improve the starting torque and efficiency of a SPIM. Some of them have focused the influence of rotor slot geometry like rotor slot type, shape, skewing, number of rotor slot, slot opening and core material.Zhou Rui et al [3], have modeled two single phase induction motors with Maxwell 2D software and changed their dimensions in Maxwell 2D to find optimal slot geometry with respect to starting performance and efficiency. In similar studies; S. Sobhani et al [4] have examined dimensions of two SPIMs and mechanical
Otomatik depolama ve boşaltma sistemleri (ODBS) firmalardaki ürünlerin depo içerisinde depolanması ve boşaltılması için kullanılan sistemlerdir. ODBS'lerde farklı depo yerleşimlerinde çeşitli otomatik depolama ve boşaltma araçları kullanılmaktadır. Bu sistemlerde yükleme ve ürün toplama işlemi genellikle kullanılan koridor robotları (KR) ve taşıyıcı robotları (TR) ile gerçekleştirilmektedir. Ürünlerin depo içerisindeki raflara yerleştirilmesinde ve toplanmasında operatör müdahalesi minimum seviyededir. Bu çalışmada ODBS'lerin tipleri, uygulanan değişik depo kurulumları ve çözümleri, ürünlerin toplanması ve yüklenmesi esnasında kullanılan optimizasyon çalışmaları hakkında yapılmış yayınlardan bir derleme yapılmıştır.
AbstractAutomated storage and retrieval systems (ASRSs) are used for loading and retrieving products in the companies' warehouses. A variety of automated storage and retrieval vehicles are used in different storage layouts in ASRSs. The loading and retrieving process is usually performed with aisle robots (ARs) and shuttle robots (SRs) at these systems. While the placement and retrieving of products on/from the shelves, the operator intervention is minimized. In this paper, a literature review has been given about ASRSs' types, applied various storage installations and solutions and optimization studies used while loading and retrieving products.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
