摘要： The invention relates to a component sensor (20) for sensing a torque component (Mx, My, Mz); wherein an element (21) made of piezoelectric crystal material has element surfaces; wherein a force component (Fx, Fy, Fz) produces electrical polarisation charges on the element surfaces; and wherein the torque components (Mx, My, Mz) to be sensed consist of at least one pair having force components (+Fx, -Fx; +Fy, -Fy; +Fz, -Fz), which force components (+Fx, -Fx; +Fy, -Fy; +Fz, -Fz) of a pair have the same axis of action and opposite directions of action. The component sensor (20) senses the force components (+Fx, -Fx; +Fy, Fy; +Fz, -Fz) of a pair separately.

摘要： A sensor system (10) and method for monitoring a powertrain (20) having a drive shaft (1). The sensor system (10) comprises an optical fibre (2) with a strain sensitive element (3). According to one aspect, a connection structure (4) is configured to hold at least a part of the optical fibre (2) with the strain sensitive element (3) at a radial distance (R2-R1) remote from the drive shaft (1) for amplifying the strain (S2) on the strain sensitive element (3) with respect to the strain (S1) on the drive shaft (1). According to a further aspect, at least three respective lengths of one or more optical fibres follow parallel, e.g. helical, paths with respect to each other to distinguish different strain forces.

摘要： A device for detecting load torque on an electric motor, adapted for use for a device for rotating a predetermined load by the motor. The device for detecting load torque can appropriately and highly accurately detect reaction of such a load, or load torque, acting on the drive output shaft of the motor. The motor is fixed to an external casing, which is a specific holding section or a stationary section, to facilitate production of the device, and a support structure is stably placed. The drive output shaft (14) is projected from one end of a housing of the motor (10), a sleeve body (16) is placed so as to surround the drive output shaft, a flange (18) is formed at one end of the sleeve body, and the flange is fixed to the one end of the housing. The other end of the sleeve body is integrally formed as an internal gear section (22) of a reduction mechanism (20) having a planetary gear (21). A strain gauge (24) is attached to the outer periphery of the sleeve body.

摘要： A sensor assembly comprises a base plate and a sensor member displaceable relative to the base plate. A spring arrangement operates in first and second stages in response to displacement of the sensor member relative to the base plate. Different resolutions of force and torque measurements are associated with the first and second stages. A light sensitive transducer senses displacement of the sensor member relative to the base plate and generates corresponding output signals. A collimator directs a plurality of light beams onto the light sensitive transducer so that the light beams strike different pixels of the light sensitive transducer to sense displacement of the sensor member relative to the base plate.

摘要： A high torque active mechanism for an orthotic and/or prosthetic joint using a primary brake which can be provided by magnetorheological (MR) rotational damper incorporating an additional friction brake mechanism driven by the braking force generated by the MR damper. This combination of MR damper and friction brake mechanism allows an increase in torque density while keeping the same level of motion control offered by the MR damper alone. The increased torque density achieved by this high torque active mechanism allows to minimize the size of the actuating system, i.e. its diameter and/or breadth, while maximizing its braking torque capability. In this regard, the friction brake mechanism is advantageously positioned around the MR damper, such that the dimension of the package is minimized.

摘要： A method for determining a load on a driven component (10) of a rotating or stationary electromechanical system includes locating a rotationally flexible shaft portion (20) in operable communication with a driving component (12) having a drive rotor (14) rotatable about an axis (26) and the driven component (10). The shaft portion (20) is operably connected thereto. Angular positions of the drive rotor (14) and the driven component (10) are determined. A magnitude of a load on the driven component (10) is calculated based on a difference in angular position of the drive rotor (14) and the driven component (10) and a known torsional rigidity of the shaft portion (20).
