After mounting the motor components, the air gap between the primary
and secondary sections can be optionally checked. Generally, this is
not necessary. If the mounting dimensions are correct, the correct air
gap is automatically obtained. If, after mounting, the air gap does not
match the data in Table 4-11, either the motor has been incorrectly
mounted, or the specified motor dimensions were not maintained when
the motor was produced.
