Brushless DC Motor

{"ID":5453905,"post_title":"Brushless DC Motor","title":"Brushless DC Motor","post_content":"In classical control of brushless dc motors, flux distribution is assumed trapezoidal and fed current is controlled rectangular to obtain a desired constant torque. However, in reality this assumption may not be correct due to non-uniformity of magnetic materials and design trade-offs. These factors together with current controller limitation, can lead to an undesirable torque- ripple. Hence torque - ripple has been the main issue of the servo derive systems, in which the speed fluctuation, vibration and acoustic noise should be minimized. This torque-ripple also deteriorates the precision of the parameters of brushless dc motors. In this proposed work, different techniques are to be carried out to control the torque - ripple of brushless dc motors. Effectiveness and flexibility of the individual techniques of torque-ripple control method will be thoroughly discussed for merits and demerits and finally verified through simulation (PSIM) and experimental results for comparative analysis.","image":"https:\/\/c5-static.dodax.com\/de-ch\/dp\/ED7FT6DJQUB-cc42c03d8d-175-175-7688557805105695289","url":"https:\/\/www.vergleiche.ch\/unterhaltung\/product\/brushless-dc-motor\/","min_price":69.900000000000005684341886080801486968994140625,"low_price_merchant_id":70254503,"deeplink":"https:\/\/www.awin1.com\/pclick.php?p=41013113314&a=401125&m=13971&pref1=9783659250798","ean":9783659250798,"brand":"undefined"}
