Configuration
3.3 Dimensioning
Motor selection
By making the appropriate iterations, a motor can now be selected that precisely fulfills the
operating conditions and application.
In a second step, a check is made as to whether the thermal limits are maintained. To do
this, the motor current at the base load must be calculated. When engineering a drive
according to the load duty cycle with a constant on period with overload, the overload current
based on the required overload torque must be calculated. The calculation depends on the
type of motor used (synchronous motor, induction motor) and the particular application (load
duty cycles with constant on period, load duty cycles with varying on period, load duty cycle).
Finally, the other characteristics of the motor must be defined. This is realized by
appropriately configuring the motor options.
