A power transmission apparatus for vehicle, incorporated in a vehicle equipped with a transmission, includes a forward-reverse switching mechanism with start function produced by adding a function of a vehicle start clutch to the forward-reverse switching mechanism. Additionally, a power transmission system for vehicle includes an internal combustion engine that is a power source for vehicle driving, the transmission, a torsional vibration damper that transmits torque of the internal combustion engine to the transmission, and the forward-reverse switching mechanism with start function of the power transmission apparatus for vehicle. The forward-reverse switching mechanism with start function is disposed between the transmission, and the internal combustion engine and the torsional vibration damper.

An electrical machine is presented. The electrical machine comprises a rotor, a stator, a housing and a fluid circuit provided between an interior of the housing and the rotor axially along a longitudinal axis of the rotor. The fluid circuit is adapted to, by means of a fluid in the fluid circuit, exert a braking torque on the rotor.

An eddy-current braking mechanism including a rotor, rotatable about a rotor axis; at least one electrically conductive member coupled to the rotor for rotation therewith; at least one magnet configured to apply a magnetic field extending at least partially orthogonal to the plane of rotation of the conductive member, and characterized in that upon rotation of the rotor, the conductive member is configured to move at least partially radially from the rotor axis into the applied magnetic field.

An electrostatic converter includes: a stator provided with at least one electrode; a rotor including at least one blade provided with a counter-electrode, the blade being movable in rotation around an axis of rotation designed to coincide with a direction of an air flow; the electrode or the counter-electrode being coated with a dielectric material able to be biased, the stator and rotor being configured to allow a first relative movement between the electrode and counter-electrode around the axis of rotation of the rotary shaft of the rotor so as to generate an electrostatic torque when the rotor performs a rotation. The stator and the rotor are configured to allow a second relative movement between the electrode and counter-electrode so as to modify the electrostatic torque generated.

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.
