Physical quantities

The list of physical quantities computed in the post-processing module and the names of the corresponding Flux parameters are given in the table below; in this table MS indicates the concerned mechanical set.

Force Name Unit Explanation
Electromagnetic force: F em ForceElecMag(MS) N
Internal system
Friction force: ForceFrInt(MS) N
Spring return force: ForceSpInt(MS) N
Inertia force: ForceInInt(MS) N
Resistant force*: ForceReInt(MS) N or
External system
Friction force: ForceFrExt(MS) N
Spring return force: ForceSpExt(MS) N
Inertia force: ForceInExt(MS) N
Resistant force * : ForceReExt(MS) N or
Note: *The resistant force is:
  • either the sum of the friction force + the spring return force
  • or the resistant force defined using a formula

Reminder of the solved mechanical equation

The solved mechanical equation for translating motion is:

where:

  • m is the mass
  • is the mass of the moving mechanical set (internal system)
  • is the mass of the external load (external system)
  • is the electromagnetic force
  • is the resistant force
  • is the resistant force acting on the moving mechanical set (internal system)
  • is the resistant force acting on the external load (external system)

Important note

When there are symmetries and periodicities, the forces are computed for the entire device.
