Number of Asymptotes Formula Elements

Variables
Number of Asymptotes
The Number of Asymptotes is the number of root locus branches starting at finite open loop poles and ending at infinite open loop zeros.
Symbol: Na
Measurement: NAUnit: Unitless
Note: Value can be positive or negative.
Number of Poles
The Number of Poles or the number of magnetic poles refers to the magnetic poles (NSNSNS……) that appear on the surface created by cutting the motor perpendicularly to the shaft.
