Harmonic Drive SE strain wave gear set consisting of wave generator bearing (top left), flexspline cup (top right) and circular spline ring (bottom). Strain wave gearing (also known as harmonic gearing ) is a type of mechanical gear system that uses a flexible spline with external teeth, which is deformed by a rotating elliptical plug to engage ...
The external coils create a harmonic flux when powered with multiple phase AC, which behaves like a variable number of stator rods- thus effecting a variable transmission or variable ratio magnetic gear. This type of gear consumes approximately 25% of its input power in the process, causing current in the external coils.
A harmonic gear or strain wave gear is a specialized gearing mechanism often used in industrial motion control, robotics and aerospace for its advantages over traditional gearing systems, including lack of backlash, compactness and high gear ratios.
Diagram of an epicyclic gearing system An epicyclic differential uses epicyclic gearing to send certain proportions of torque to the front axle and the rear axle in an all-wheel drive vehicle. [ citation needed ] An advantage of the epicyclic design is that it is relatively compact width (when viewed along the axis of its input shaft).

A transmission (also called a gearbox) is a mechanical device which uses a gear set—two or more gears working together—to change the speed, direction of rotation, or torque multiplication/reduction in a machine. [1] [2] Transmissions can have a single fixed-gear ratio, multiple distinct gear ratios, or continuously variable ratios. Variable ...
In an electric power system, a harmonic of a voltage or current waveform is a sinusoidal wave whose frequency is an integer multiple of the fundamental frequency. Harmonic frequencies are produced by the action of non-linear loads such as rectifiers , discharge lighting , or saturated electric machines .
A hub gear, [1] internal-gear hub, [2] internally geared hub [3] or just gear hub [4] is a gear ratio changing system commonly used on bicycles that is implemented with planetary or epicyclic gears. The gears and lubricants are sealed within the shell of the hub gear, in contrast with derailleur gears where the gears and mechanism are exposed ...
