Basic formulae

11.2.1

General movement equations

The variables required for sizing and selecting the motor are calculated using

the equations shown in the following.

The process-related feed forces and speeds are used directly for

drive selection during project planning of linear direct drives with‐

out conversions.

v(t)

Velocity profile over time in m/s

s(t)

Distance course over time in m

a(t)

Acceleration profile vs. time in m/s²

F(t)

Force course over time in N

Moved mass in kg

(t)

Base force and friction in N

(t)

Processing force or operation force in N

eff

Effective force in N

avg

Average velocity in m/s

Time in s

Total time in s

General equations of motion

In most cases the mathematical description of the required positions vs. the

time is known (NC-program, electronic cam disk). By means of path function,

the calculation of velocity, acceleration and force can be done. Standard soft‐

ware (such as MS Excel or MathCad) can be used for calculating the re‐

quired variables, even with complex motion profiles.

The following chapter provides a more detailed correlation for tra‐

pezoidal, triangular or sinusoidal speed curves.
