Electromagnetic Brake

Leading a significant product development initiative, I spearheaded the design of a new electromagnetic brake to expand our product line. This involved in-depth exploration of electromagnetics to engineer an optimal coil design tailored for diverse applications. My responsibilities encompassed researching and selecting reliable, machinable, and cost-effective electromagnetic materials, as well as understanding the intricacies of friction materials crucial for brake functionality. Navigating manufacturing limitations, I identified and collaborated with external vendors, effectively communicating project requirements and objectives to ensure successful component sourcing. This effort culminated in a comprehensive cost analysis and the creation of functional prototypes. Rigorous internal testing and validation against industry standards like UL were integral to the development process. Throughout this project, I actively engaged in continuous learning, delving into electromagnetic simulations to validate designs and developing valuable tools to aid in prototype construction. While the product's market launch occurred after my involvement, the experience of driving this project and acquiring new knowledge was immensely rewarding.

Phase 1

Phase 1 of the electromagnetic brake project centered on rapid prototyping and initial design exploration. This involved the procurement of machined parts and a significant amount of hands-on experimentation. Facing a lack of proficiency in FEMM simulation at this stage, I adopted a trial-and-error approach to understand the system's behavior. This iterative process highlighted the time-intensive and intricate nature of coil manufacturing, prompting the development of a small automation system to streamline the winding process. The culmination of this phase was a functional proof-of-concept prototype, which then informed a subsequent design refinement phase.

Phase 2

Phase 2 marked a significant evolution in the electromagnetic brake project with substantial design revisions. A key advancement in this stage was my acquisition and implementation of FEM (Finite Element Method) simulation capabilities. This dramatically accelerated the design process, providing a deeper understanding of the system's behavior. With a clearer grasp of the design constraints, I developed simulations to explore the impact of various coil parameters – dimensions, number of turns, and wire gauge – on critical performance characteristics such as thermal capacity, power consumption, and electromagnetic force. This simulation-driven approach allowed for efficient optimization and informed design decisions.
