Project Overview
The objective of this project is to design a Voice Coil Actuator (VCA) capable of precise linear motion control for a ventilator valve. Unlike solenoid valves, VCAs offer proportional control, which is critical for regulating airflow in medical devices.
Technical Implementation
The design process involves calculating the required Lorentz force based on the valve's pressure requirements. I am currently using FEMM (Finite Element Method Magnetics) to simulate the magnetic flux density and optimize the coil winding geometry for maximum efficiency.
Challenges & Solutions
Challenge: Maintaining a consistent magnetic field throughout the stroke length.
Solution: Designing a custom iron core geometry to focus the magnetic flux lines directly through the coil path.
