摘要： An angle detector for detecting an amount of angular change due to the rotation of a rotary body. The angle detector is provided with a rotary body rotating around a rotation axis, a graduated scale having a plurality of graduations along the circumference of the rotary body in a rotation direction, and a plurality of sensors disposed along the circumference. Each of the sensors outputs a signal according to an amount of angular change on the basis of the plurality of graduations. The output signal includes a fundamental wave component having one of the plurality of graduations as a first period first order, and a harmonic wave component having an order that is an integer multiple of at least two times the fundamental wave component. An amount of angular displacement calculated from the output signal includes an angular error component that is due to the harmonic wave component and has an order component that is an integer multiple of the one graduation that is the first period first order. The number of the plurality of sensors is determined on the basis of the number of graduations on the graduated scale and the order component of the angular error component.

摘要： Disclosed is a quasi-zero stiffness absolute displacement sensor based on electromagnetic positive stiffness, and relates to the technical field of vibration measurement. The quasi-zero stiffness absolute displacement sensor comprises an eddy current displacement sensor unit, a negative stiffness unit, an intermediate connector, a positive stiffness unit, a bottom shell and a motion axis. The damping of the mechanism can be effectively reduced, the service life of the system is prolonged, and the mechanism size is reduced. By adjusting the number of layers of permanent magnets and coils in the electromagnetic positive stiffness unit and the electromagnetic negative stiffness unit and controlling the magnitude of current in the coils, electromagnetic force between the permanent magnets and the electromagnetic coils can be changed, the magnitude of positive stiffness and the magnitude of negative stiffness are adjusted, and control over the stiffness of the whole system is achieved.

摘要： A magnetorheological braking device for setting operating states by way of rotational movements has an axle unit and a rotary body rotatable about the axle unit. The rotatability of the rotary body can be decelerated and/or blocked by a magnetorheological braking apparatus. A sensor apparatus has a magnetic ring unit and a magnetic field sensor for sensing a magnetic field of the magnetic ring unit. A shielding apparatus at least partially shields the sensor apparatus from a magnetic field of a coil unit of the braking apparatus. The shielding apparatus includes a shielding body surrounding the magnetic ring unit and a separating unit between the shielding body and the magnetic ring unit, and having a magnetic conductivity multiple times lower than the shielding body. A holding apparatus connects the shielding apparatus to the rotary body in an at least partially rotationally fixed manner.

摘要： To reduce the influence of an unintended magnetic flux of a permanent magnet on detection accuracy. An absolute encoder (2) includes a magnet provided at a tip end side of any one of a first worm gear portion (11) and a second worm gear portion (22), and an angle sensor configured to detect a rotation angle of the magnet in response to a change in magnetic flux generated from the magnet. In the magnet, a first magnetic pole portion of a first polarity and a second magnetic pole portion of a second polarity different from the first polarity are formed adjacent to each other as viewed from an axial end surface of the magnet. The first magnetic pole portion and the second magnetic pole portion are formed adjacent to each other in a radial direction with a radial center of the magnet as a boundary, and the first magnetic pole portion and the second magnetic pole portion are formed adjacent to each other in an axial direction with an axial center as a boundary. The absolute encoder (2) is provided with a magnetic interference reduction member formed of a magnetic material on a radially outer peripheral surface of the magnet.
