Abstract
An angle sensor is provided that includes a multilayer substrate having multiple layers, a drive coil in the multilayer substrate, and first and second detection coils, which can be two-phase detection coils, that are provided in the multilayer substrate. Each of the multiple layers in the multilayer substrate has a first main surface and a second main surface facing each other. The drive coil and the first and second detection coils are provided on respective different main surfaces, among the first main surfaces and the second main surfaces of the multiple layers in the multilayer substrate.
Claims20
An angle sensor comprising:
- a multilayer substrate having a plurality of layers that each have main surfaces that face each other;
- a drive coil disposed in the multilayer substrate;
- and
- two-phase detection coils disposed in the multilayer substrate,
- wherein the drive coil and the two-phase detection coils are disposed on different main surfaces, respectively, of the main surfaces of the plurality of layers.
An angle sensor comprising:
- a multilayer substrate having at least a first layer with opposing first and second main surfaces and a second layer with opposing first and second main surfaces, with the first main surface of the second layer being directly coupled to the second main surface of the first layer;
- a drive coil disposed on the first main surface of the first layer;
- and
- two-phase detection coils disposed in the multilayer substrate and on the first main surface of the second layer and the second main surface of the first layer.
