Solution
To calculate the force-versus-position characteristic, the plunger position is varied from 0 to 10 cm. LabelMover
automatically modifies the geometry in increments of 1 cm. The mechanical force is calculated at each position.
The nominal plunger position is 10 ± 0.5 cm, and the nominal current density is 4 A/mm² ± 10%. We use LabelMover Tolerance Analysis to study the effects of the current density and plunger position on the mechanical force.
The force can be maximized by increasing the height of the core window. This allows more coil turns to be added,
producing a greater electromagnetic force. However, increasing the window height also increases the magnetic core
reluctance. LabelMover Optimization is used to find the core-window height that provides the maximum force.
Result:
The current and plunger position influence on mechanical force:
To get the maximal force the core window height should be 40 mm + 31.73 mm (initially it was 40 mm). The pull force is 1327 N (it was 436 N initially).
