ABSTRACT:
An analog-display device, such as a gauge or the like, includes a moveable display member driven by a planar micro-motor. The micro-motor comprises a substrate, a stator for receiving electrical current to generate an electromagnetic field, and a rotor which is rotatable in response to electromagnetic fields generated by the stator. In the stator, a plurality of electrically conductive micro-coils are supported by the substrate and arrayed in a first plane. A plurality of magnetic members is arrayed in the rotor in a second plane substantially parallel to the first plane. The visible display member of the analog display device is mounted for movement by rotation of the rotor body. Analog display devices of the invention can be used in motor vehicle instrument panels, wherein the micro-motor carrying the display member can be mounted, as by cementing, to the display face of the device.
