Configuring the motor 

 

5.2 Example(s) 

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

STR

 (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.
