I need the elctromagnetic calculations for a custom designed moving magnet voice coil actuator system.
Please see attached drawing for further details. Dimension can be adapted if neccesary.
Magnet travel ±15mm
Force 50N (±10N)
Brief FEMM simulation is attached.
A. Calculations in FEMM 4.2 or similar
B. Definition of electrical properties
1. Proof of concept
2. Calculation data
3. Coil specification
