What is an Air Core Meter Gauge Movement?

An air core gauge is a specific type of rotary actuator in an analog display gauge that allows an indicator to rotate a full 360 degrees. It is used in gauges and displays, most commonly automotive instrument clusters.

A typical automotive application is shown at the right. The air core gauge is a type of "air-core motor". It may be considered a "gauge movement" or "pointer indication device".

Air-core movements (air core motor) are robust gauge mechanisms commonly used in automotive and marine gauges. An air-core is simply a very basic electric "motor" with a permanent magnet rotor and no commutator brushes. It's called an "air-core" because there is no iron in the magnetic path. It really has plastic in the magnetic path instead of air, but "plastic-core" just didn't make it.
