Abstract
A method for determining a load on a driven component of a rotating or stationary electromechanical system includes locating a rotationally flexible shaft portion in operable communication with a driving component having a drive rotor rotable about an axis and the driven component. The shaft portion is operably connected thereto. Angular positions of the drive rotor and the driven component are determined. A magnitude of a load on the driven component is calculated based on a difference in angular position of the drive rotor and the driven component and a known torsional rigidity of the shaft portion.
Claims19
An electromechanical system comprising:
- a driving component having a drive rotor rotable about an axis;
- a driven component rotable about the axis;
- and
- a rotationally flexible shaft portion disposed in operable communication with the drive rotor and the driven component and operably connected thereto such that rotation of the drive rotor about the axis drives rotation of the driven component about the axis, wherein a difference in the amount of rotation of the drive rotor and the driven component is indicative of a load on the driven component.
