A magnetically-coupled torque assist apparatus includes a movable (rotor) magnet configured to rotate about a rotor magnet axis extending through the rotor magnet, and a stationary (stator) magnet. The rotor magnet and the stator magnet have a gap therebetween. There is an equilibrium state position (ESP) of the rotor magnet where forces acting on the rotor magnet are balanced such that the rotor magnet is stationary about the rotor magnet axis. And when the rotor magnet is rotated from the equilibrium state position (ESP) to an elastically stressed state position (SSP), magnetic fields of the rotor magnet and the stator magnet generate a resultant magnetic force on the movable magnet that biases the movable magnet towards the equilibrium state position. In some embodiments, the stator and rotor magnets are configured to create a Halbach-effect magnetic field bloom, which contributes to the magnetic forces.

Systems, methods, and apparatus related to a homing mechanism within a drive mechanism of a lacing engine for an automated footwear platform are described. In an example, the homing apparatus can include an indexing wheel, a plurality of Geneva teeth and a stop tooth. The plurality of Geneva teeth can be distributed around a portion of a perimeter of the indexing wheel. Each Geneva tooth of the plurality of Geneva teeth can include side profiles conforming to a first side profile that generates a first force when engaged by an index tooth on a portion of the drive mechanism. The stop tooth can be located along the perimeter of the indexing wheel between two Geneva teeth. Additionally, the stop tooth can include side profiles conforming to a second side profile that generates a second force when engaged by the index tooth.

A hybrid spherical motor includes a first gear box, a second gear box, a yoke arm, a brushless direct current (BLDC) motor, a spherical stator, and a spherical armature. The split armature, in response to the spherical stator being energized, rotates about a first rotational axis, thereby causing the first gear box input connection and the second gear box input connection to rotate about the first rotational axis, and the yoke arm rotates about the first rotational axis in response to the first gear box input connection and the second gear box input connection being rotated about the first rotational axis, whereby the BLDC motor rotates about the first rotational axis.

A valve device includes a valve, a drive device, and a transmission unit. A valve changes a flow mode of refrigerant that flows in a circulation path of a refrigeration cycle device. The transmission unit includes a driving-side rotary body, a magnetic transmission member, and a driven-side rotary body. The driving-side rotary body includes multiple magnetic magnet poles in a rotational direction. The magnetic transmission member includes multiple magnetic transmission bodies which are configured to be magnetized by the magnetic magnet poles. The driven-side rotary body includes multiple magnetic magnet poles in a rotational direction. The driven-side rotary body rotates in response to a rotary motion of the multiple magnetic magnet poles of the driving-side rotary body via the magnetic transmission body. The number of the magnetic magnet poles and the number of the magnetic transmission bodies are different from each other. The rotation is transmitted from the driving-side rotary body to the driven-side rotary body via the magnetic transmission member in a non-contact manner.

A device for adjusting an object, for example a roll in a roll stand including a rotatably mounted pressure spindle and a torque motor having a stator and a rotor for rotationally driving the pressure spindle. In addition, the device includes a fixedly arranged pressure nut, which is engaged with the pressure spindle in a rotationally coupled manner via a thread to generate an axial movement of the pressure spindle in case of its rotation. Due to the axial movement generated in this way, the device can generate an axial adjustment force and transmit it to the object to be adjusted.

A two-dimensional motor and a servo valve are provided. The two-dimensional motor includes a stator and a rotator arranged coaxially. The stator is enclosed in the rotor. The stator and the rotor are spaced along a radial direction of the rotor. A size of the stator along an axial direction is greater than a size of the rotor along the axial direction. The rotor is, without bearing support, directly connected to an external mechanism. The rotor is swung at a predetermined angle, such that the external mechanism can drive the rotor to move along an axial direction of the rotor relative to the stator.
