STICTION

Stiction
Inputs(2) Torque w
Parameters(3) Range Maximum p3
Default Range=1, Maximum=1, p3=1,
Select from Components/Blocks/Machines
Function TStiction is substracted from the input torque (Torque). If the result is positive, e.g. the input torque is larger than TStiction, the output y equals the difference between Torque and TStiction. If the result is negative, the output y equals zero. TStiction is determined by:
Special
p3=1
w<-Range
-Range<w<0
0<w<Range
Range<w
TStiction=0
TStiction=-(Maximum/Range)Torque+Maximum
TStiction=-(Maximum/Range)Torque+Maximum
TStiction =0
   
p3=2
w<-Range
-Range<w<Range
Range<w
TStiction =0
TStiction =Maximum
TStiction =0

 

Where

Torque
w
Range
Maximum
Input torque from an electrical machine
Speed
Range of the stiction
Maximum stiction


The output y equals the input torque Torque minus TStiction. If the input torque Torque is smaller than TStiction the output y equals zero.
