The material for permanent magnet is NdFeB (Neomax 38) and structure is SS400 \( (1.8 \mathrm{~T}) \). The coil diameter use for this motor is 0.3 mm . 1. Explain how this Linear actuator works? 2. What is the fundamental equation for the thrust of this type of actuator? 3. Draw the flux flow inside the actuator. 4. Draw the magnetic circuit for this actuator. 5. Calculate the coil turn and resistance for this actuator. 6. Calculate the permeance and permanent magnet operating point. 7. Calculate the thrust for this motor if 3 A and 5 A of current were injected. 8. Calculate the best thicknesses for iron in point B.
