5.2.6 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
MAX,MMAX
specified for the motor type at the maximum torque M
MAX
. In this case, a check must be
made based on the motor torque-speed diagram. This diagram is included with the motor
specifications.
Figure 5-5 Motor torque-speed diagram
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.
