5.2 Configuring workflow
In summary, the motor is selected as follows:
SINAMICS ALM 400 V line supply (600 V DC link voltage)
M in Nm; n in rpm

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 rules for this
purpose depend on the type of motor used (synchronous motor, induction motor) and the
operating scenario (duty cycles with constant or with different switch-on duration).
