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.
Claims20
A rotary position sensor comprising:
- a rotor assembly comprising a rotor assembly opening for securing the rotor assembly to a shaft structure;
- a stator assembly comprising a stator assembly opening for receiving the shaft structure;
- and
- 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,
- wherein radiuses of the plurality of primary coil elements are different,
- wherein the rotor assembly comprises a plurality of rotor plates,
- wherein the plurality of rotor plates are in an annular sector shape and have same size,
- wherein the plurality of rotor plates are alternatingly positioned on the rotor assembly such that the plurality of rotor plates are not connected to one another,
- wherein a rotor sector angle of each of the plurality of rotor plates is based on a rotor plate number such that the rotor sector angle equals 360 degrees divided by twice the rotor plate number, and
- wherein the plurality of rotor plates comprise material having magnetic permeability.
