Magnetically-coupled torque-assist apparatus

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.

Hybrid spherical motor, system, and aerial vehicle incorporating the same

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.

Valve device

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.
