Linear Motor

Force, duty cycle and thermal limits for a linear motor stage.

Linear Motor Design DashboardExplore thrust, force density, and geometry for a low-profile linear motor.
Force vs CurrentBased on a simplified thrust constant scaling with pole pitch, magnet height, fill factor, and active length.
Geometry & InputsPole pitch τ (mm)
Magnet height (mm)
Slot fill factor
Active length (mm)
Stack height (mm)
Max phase current (A RMS)
Derived MetricsThrust constant Kt
13.33 N/A
Max thrust @ Imax
106.7 N
Estimated active mass
2.89 kg
Force density @ Imax
36.9 N/kg
SummaryPole pitch τ18 mm
Magnet height4 mm
Slot fill factor0.45
Active length300 mm
