equivalent reduction in the drive costs. As the two windings share the same pole, there
is close magnetic coupling between the coils; this must be taken into account when
designing a drive system.

8.5 Summary
This chapter has briefly reviewed the theory and control of a range of stepper motors,
and it has been shown that stepper motors are able to provide a low-cost solution to
motion-control problems, provided that the limitations of the motors are fully appre-
ciated during the design process.
