Determining the motor torque-speed diagram
If the motor torque-speed diagram is not available, then determine the motor torque-speed
diagram from the following data taken from the "Motor torque speed diagram" figure.
● Maximum torque M
MAX
with the associated speed n
MAX,MMAX
● Rated torque M
N
with the associated speed n
N
In this diagram, transfer all operating points of the duty cycle from the motor torque-time
diagram and the speed-time diagram. Generally, you only have to search for critical points in
time in the torque-time diagram. Critical points in time are when the maximum speed
exceeds the n
MAX,MMAX
at peak torque.
For these points in time, determine the motor torque (in the example M
1
) from the motor
torque-time diagram. Check whether the motor torque lies below the characteristic in the
motor torque-speed diagram.
