[M
max
]: Corresponds to the theorectically possible maximum torque of the
motor. The value can be limited by the drive controller.
[1]-[4]: Characteristic voltage limit curves. When a speed at the safe
commutation limit is reached, the voltage limit curve limits the
available maximum torque M
max
. The maximum motor speed is
determined by the DC link voltage used. There are separate
characteristic curves for the various drive controllers in connection
with the power supply unit and the supply voltage used.
