tailieunhanh - A new design of single side brushless direct current linear motor

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. | Journal of Automation and Control Engineering Vol. 3, No. 4, August 2015 A New Design of Single Side Brushless Direct Current Linear Motor Mahir Dursun and Ali Saygın Faculty of Technology, Department of Electrical and Electronics Engineering, Gazi University, Ankara, Turkey Email: {mdursun, asaygin}@ Semih Özden 1 and Ahmet Fenercioğlu 2 1 2 Electricity and Energy Department, OSTIM Vocational High School, Gazi University, Ankara, Turkey Dept. of Mechatronics Engineering, Faculty of Engineering and Natural Sciences, Gaziosmanpaşa University, Tokat, Turkey Email: sozden@, ahmetfenercioglu@ Abstract—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. Index Terms—permanent magnet, linear motor, brushless dc motor, motor design I. INTRODUCTION To convert electrical energy to mechanical energy electric motors is used. In many industrial systems a linear force is required. On the other hand, to linear motion from a circular electric motor to achieve many additional parts are needed. Also the cost of this process is so high, reliability, position control, and increases the need for maintenance. So, in the industrial applications it is needed to linear motors. A LBLDC .
