Motor continuous usage
In this chapter you can read about:
Linearized motor characteristic lien for different operating points ................................... 183
This kind of monitoring watches over the continually deliverable torque (continuous
current). This continuous current depends on the velocity and is acquired online
from the linearization of the motor characteristic line.
