Define the load case, calculate the maximum torque, select the motor

The motor-specific limiting curves are used as basis when selecting a motor.
These define the torque characteristic with respect to speed and take into account the motor
limits based on the line supply voltage and the function of the infeed.

M in Nm; n in rpm

The motor is selected on the basis of the load specified by the application. Different
characteristics must be used for different loads.
The following operating scenarios have been defined:
● Load duty cycles with constant on period
● Load duty cycles with varying on period
● Duty cycle, variable
