Motor torque-speed diagram

Checking torques and speeds
At high speeds, the maximum available motor torque is limited by the available DC link
voltage.
The speeds occurring in the motion sequence can exceed the maximum speed n
specified for the motor type at the maximum torque M
made based on the motor torque-speed diagram. This diagram is included with the motor
specifications.
Figure 5-5
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
● Rated torque M
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
For these points in time, determine the motor torque (in the example M
torque-time diagram. Check whether the motor torque lies below the characteristic in the
motor torque-speed diagram.
