The output sine wave would be slightly smaller than the input and will exhibit a small phase shift.

The real beauty of the Bode diagram is its use in analyzing compensation techniques and the effects
of loads and machine resonances. Loads and resonances limit the gain one can use without incurring instability. Compensation techniques allow one to increase A at low frequencies while maintaining
the frequency bandwidth (the frequency where A = 1). These compensation techniques are the things
that the vendors normally tout.

The purpose of this month's column has been to provide a basic understanding of Bode diagrams so
you can better understand vendor offerings. If you comprehend what has been written here, you will
know more about Bode diagrams than I do about women after 31 years of marriage (which means we
both still have a lot to learn). Certainly this new found knowledge will not make you a "10" as a
servo expert, but there aren't many Bo Dereks around, either.

Torque Generation
The torque produced by a stepper motor depends on several factors.
• The step rate
• The drive current in the windings
• The drive design or type
In a stepper motor a torque is developed when the magnetic fluxes of the rotor and stator are displaced from each other. The stator is made up of a high permeability magnetic material.

The presence of this high permeability material causes the magnetic flux to be confined for the most part to the paths defined by the stator structure in the same fashion that currents are confined to the conductors of an electronic circuit. This serves to concentrate the flux at the stator poles. The

Figure 5. Magnetic flux path through a two-pole stepper motor with a lag between the rotor and stator.
Figure 6. Unipolar and bipolar wound stepper motors. torque output produced by the motor is proportional to the intensity of the magnetic flux generated when the winding is energized.
The basic relationship which defines the intensity of the magnetic flux is defined by:
H = (N × i) ÷ l where:
N = The number of winding turns
i = current
H = Magnetic field intensity
l = Magnetic flux path length
This relationship shows that the magnetic flux intensity and consequently the torque is proportional to
the number of winding turns and the current and inversely proportional to the length of the magnetic flux path.
From this basic relationship one can see that the same frame size stepper motor could have very different torque output capabilities simply by changing the winding parameters. More detailed information on how the winding parameters affect the output capability of the motor can be found in the application note entitled “Drive Circuit Basics”.
