Customer form factor examples catalog
All torque/cadence sensors are customized to fit a unique mechanical design. These rotor-stator form factor examples are solutions our customers have come up with. Each of these solutions fits into one of three major categories:
- Radially constrained designs where the difference between outer diameter (OD) and inner diameter (ID) is restricted. Typically where the sensor fits on a shaft next to a bearing and cannot take up more radial space than the bearing.
- Axially constrained designs where the total width of the sensor solution is limited. Typically where the sensor is working on a disk/spider surface and needs to fit between the torque-sensing disc-shaped metal and some other wall.
- In-between where the 3D space available is constrained in both directions. This can be inside a gearbox or some other complex-shaped system.
When designing for this technology, it may help to start out with an existing example below and modify the mechanical shape from there. If you need OD < ID + 15mm, please get in touch to discuss the details.
Example 3D CAD files
These are just some examples of rotor-stator form factor. Let us know what you are looking for and we may have other examples you can use.
“R” = Rotor part of the sensor. The rotor is the moving/rotating part.
“S” = Stator part of the sensor. The stator is the stationary part.
“ID” = Inner diameter. The biggest shaft that can fit a given sensor set is set by the smallest ID.
“OD|Box” = Outer diameter (for some shapes indicating the bounding box makes more sense)
Bold text = Based on the newest SG3Q technology including absolute angle sensing
The air gap between the rotor and stator is typically 1-2 mm and can be tuned to larger air gaps as needed.
All 3D CAD files are in STEP format. The files are showing how the final sensor parts may look including the over-molding for environmental protection (grease, oil, water, etc.)
Please get in touch (below) if you need other file formats, thinner, larger, smaller, different mounting, etc. The technology is quite flexible and quick/easy to customize for a perfect fit.
It is important that you consider the sensor requirements during the early stages of the mechanical design process in order to ensure seamless integration of the components into the overall design.
