A linear motion system utilizing one or more printed circuit boards embedded within a stage wherein the system components, including the controller, drive, and controller, may be mounted to a printed circuit board (PCB), and the electrical communications between the system components and the power to the system components are supplied through traces or etchings on the printed circuit board, thereby omitting the need for additional power and communication cables.

Embodiments of the disclosure provide a magnetically geared DC brushless motor and method of using the same. The motor may use multiple separately terminable winding sections wrapped around motor armatures. At least one of the separately terminable winding sections may have windings around adjacent armatures. The motor may be configured to activate certain winding sections to control the velocity and torque outputs of the motor. The winding sections may include copper wire, and the separate winding sections may have wires of different gauge sizes. Various winding sections may be powered by separate voltage sources. Various winding sections may be powered by separate pulse-width modulation voltage sources. The motor may be configured to increase and/or decrease the voltage of a winding section or combination of sections to prepare for the activation or deactivation of another winding section or combination of winding sections.

An electric machine includes a rotor having a magnetic field generating device for generating a magnetic flux. A flux changing apparatus of the electric machine includes an axially displaceable body that is disposed axially outside the magnetic field generating device for changing a magnetic flux within a gap between the rotor and a stator in dependence upon an axial position of the body relative to the rotor. The flux changing apparatus includes an adjusting device for axially adjusting the axial position of the body relative to the rotor. The adjusting device includes an actuator and an adjusting element. The actuator acts on the body via the adjusting element. The adjusting element engages the body and/or the actuator in such a manner that a rotational movement of the body can be decoupled from the adjusting element, a housing of the electric machine, the rotor and/or the actuator.

An electrical machine comprising a two-part rotor formed of a first rotor part and a second rotor part. The first rotor part includes a conical section and is mounted to a shaft of the machine. The second rotor part has a bore including a complementary conical section. The second rotor part is configured to displace axially between a first state, in which it is engaged with the first rotor part to form the rotor of the electrical machine, and a second state, in which it is axially disengaged from the first rotor part. Also a clutch having an engaged state and a disengaged state. When the clutch is in one of its states the second rotor part is in its first state and switching the clutch to the other of its states axially displaces the second rotor part to its second state.

A linear motor comprises a stator, the stator comprising multiple drive coils and an intermediate circuit electrically conductively connected to each drive coil, the intermediate circuit being configured to exchange energy with each drive coil. The drive coils are arranged along the running rail, where at least one slide comprising a magnet acting as a rotor of the linear motor is movably arranged on the running rail. A controller is configured to independently control each drive coil, so that electrical energy is fed from the intermediate circuit into the drive coils, if a measured intermediate circuit voltage is greater or equal to a predetermined intermediate circuit voltage threshold value, where those drive coils are excluded from the feed-in of the electrical energy which are instantaneously being used for driving or braking the at least one slide and/or have a thermal load which exceeds a predetermined thermal load threshold value.

An eccentric magnet rotates around a spool under the influence of an electric field generated by a rotational coil surrounding the magnet to produce haptic output by rotational vibration. The ends of the spool are connected to springs, and linear actuating coils are disposed near the respective ends of the spool to cause the spool and, hence, the magnet rotating around it, to reciprocate, generating additional haptic output from the vibrations of the reciprocating motion.

A rotating power amplifying apparatus includes a main shaft having a horizontally installed central axis, a main rotating body supported by the main shaft and rotatable about the central axis of the main shaft, and a repellent force generating mechanism installed around the central axis, having a repellent force generating member displaceable about the central axis, configured to displace the repellent force generating member and generate a repellent force by rotation of the main rotating body, and configured to rotate the main rotating body.
