To serve their purpose as a long, slender, round piece of wood or metal. Usually, they're used to support something. I'd say that's a pretty good description of their purpose; wouldn't you say?

In a driving point function, poles and zeros must adhere to specific restrictions to ensure system stability and physical realizability. Poles should be located in the left half of the complex plane for stability, while zeros can be placed anywhere, though their placement affects the system's response. Additionally, the number of poles must be greater than or equal to the number of zeros for the function to remain proper. This ensures that the driving point function behaves appropriately within the constraints of physical systems.
The function of a magnetic compass is to show the direction toward the magnetic poles of the Earth. It is used as a navigation tool.
The network function h(s) is actually the ratio of two polynomials functions i.e s(a) /s(b),The roots of the s(a) function are called zeros and the roots of the s(b) function are called poles.
In a driving point function, poles and zeros must adhere to specific restrictions based on the nature of the system being analyzed. Poles, which represent system dynamics, must be located in the left half of the complex plane for the system to be stable (for continuous-time systems). Zeros can be located anywhere in the complex plane, but their placement can influence the system's frequency response. Additionally, for a physically realizable driving point function, poles and zeros must occur in conjugate pairs if they are not real.
The number of poles on stator and rotor is always the same. If they are not equal?æno torque will be produced, thus, the machine will not function.?æ
poles are the plot of the transfer function of a system on the left side of the origin, in s-plane. zeroes are the right side plot. poles and zeroes specifies the absolute stability of the system.. they also gives the observability and controllability of the system..
These are values which make the denominator equal zero, therefore the system described by the transfer function would be unstable near these values.
Frequency is a function of the speed of the alternator and the number of poles. The symbol for 'hertz' is 'Hz', not'hz'.

Motor proteins require ATP (adenosine triphosphate) to function in the movement of chromosomes toward the poles of the mitotic spindle. ATP provides the energy necessary for motor proteins to move along microtubules and exert force on the chromosomes to move them to their desired location.
