Check of the air gap height
Note
Installation dimension and air gap
The installation dimension mus
t lie within the specified tolerances along the entire traversing
If the installation dimension matches, the correct air gap height will automatically result.
If, however, the installation dimension matches, but the correct air gap height does not
re
sult, there is generally an installation error.
A correct air gap height is critical for keeping the electrical characteristics of the motor in
accordance with the data sheet.
After the installation, use tear-resistant spacer foil with a constant thickness as an aid in
checking to ensure that a minimum air gap height has been complied with.
For secondary section with cover sheet:
mm
For secondary section without cover sheet:
mm
You can find the manufacturer's recommendation for spacer foil in the annex.
1. Slide the spacer foil into the air gap between the primary and secondary sections.
The spacer foil must not jam. It must be easily moveable along the entire length of the air
gap by hand with minimal use of force.
2. Slide the primary section over a section of the secondary section track that has not yet
been checked. Repeat the check.
3. Repeat this procedure until the entire length of the secondary section track has been
checked.
Air gap height is too small
If the check determines that an air gap height is too small, then the prescribed installation
dimensions were not complied with or there is an installation error.
The machine must not be put into operation.
• Ensure that the installation dimensions of the machine are within tolerance.
