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.
