The speed n in rpm can be converted to the angular velocity as follows:
Example: converting the speed n = 80 rpm to the angular velocity ω
The value for the rated temperature of the motor winding must be applied for the phase
resistance R

(T) (see also "Explanations of the formula abbreviations").
This equation can be used for every point in time in the duty cycle.
Selecting an infeed unit
When you select an infeed unit for the DC link for highly-dynamic direct drives, it is generally
sufficient to determine the peak infeed power that occurs in the duty cycle because the
continuous power is usually much lower. The peak infeed power is normally required when
the motor accelerates to the maximum speed (see operating point M
1
in "Motor torque-speed
diagram with the required operating point M
1
").
If more than one axes is operated, the infeed powers of the individual axes must be added
together with the corresponding simultaneity conditions for the purpose of selecting the
infeed unit.
