Abstract
Apparatuses, systems, and methods for sensing rotary positions are provided. For example, an example rotary position sensor includes a rotor assembly having a rotor assembly opening for securing the rotor assembly to a shaft structure, a stator assembly having a stator assembly opening for receiving the shaft structure, and a base assembly secured to the stator assembly. In some examples, the base assembly (such as, but not limited to, a PCB assembly) comprises a plurality of primary coil elements printed on a first side of the base assembly and a plurality of secondary coil elements printed on a second side of the base assembly.
Claims15
A method of manufacturing a rotary position sensor, the method comprising:
- securing a rotor assembly to a shaft structure through a rotor assembly opening of the rotor assembly;
- securing a stator assembly to the shaft structure through a stator assembly opening of a stator assembly, and
- securing a base assembly secured to the stator assembly, wherein the base assembly comprises a plurality of primary coil elements printed on a first side of the base assembly and a plurality of secondary coil elements printed on a second side of the base assembly,
- characterised in that, the radiuses of the plurality of primary coil elements are different.
A rotary position sensor comprising:
- a stator assembly, comprising:
- a stator shell defining a stator assembly opening;
- and
- a plurality of stator plates associated with high magnetic permeability, wherein each of the plurality of stator plates is secured within the stator shell and disposed about the stator assembly opening, wherein the plurality of stator plates are in an annular sector shape defined by at least an annular sector angle, an outer diameter of the plurality of stator plates and an inner diameter of the plurality of stator plates;
- and
- a base assembly secured to the stator assembly, wherein the base assembly comprises at least a plurality of primary coil elements printed on a first side of the base assembly, wherein radius of each primary element in the plurality of primary coil elements is different.
