<div>With the rapid development of electric vehicles, need for improved reliability and safety performance vehicle braking systems has become paramount. In response to this demand, a novel direct-drive brake-by-wire actuator based on linear motors was designed address these challenges. This article presents structure principles proposed actuator. Leveraging traditional electromechanical brake as foundation, prototype modified fabricated. Additionally, control drive system established using TMS320F28335 digital signal processor. Moreover, current-position dual closed-loop algorithm devised regulate force accurately. Experimental results demonstrate that exhibits responsiveness precise modulation, showcasing promising prospects in field braking.</div>
