Wingdings. Wingdings is a TrueType dingbat font included in all versions of Microsoft Windows from version 3.1 [ 4] until Windows Vista/Server 2008, and also in a number of application packages of that era. [ 5] The Wingdings trademark is owned by Microsoft, [ 4] and the design and glyph order was awarded U.S. Design Patent D341848 in 1993. [ 6]
Armature (electrical) A DC armature of a miniature motor (or generator) A partially-constructed DC armature, showing the (incomplete) windings. In electrical engineering, the armature is the winding (or set of windings) of an electric machine which carries alternating current. [ 1] The armature windings conduct AC even on DC machines, due to ...
A vortex generator ( VG) is an aerodynamic device, consisting of a small vane usually attached to a lifting surface (or airfoil, such as an aircraft wing) [1] or a rotor blade of a wind turbine. [2] VGs may also be attached to some part of an aerodynamic vehicle such as an aircraft fuselage or a car. When the airfoil or the body is in motion ...
Van de Graaff generator. A Van de Graaff generator is an electrostatic generator which uses a moving belt to accumulate electric charge on a hollow metal globe on the top of an insulated column, creating very high electric potentials. It produces very high voltage direct current (DC) electricity at low current levels.
Electric generator. U.S. NRC image of a modern steam turbine generator (STG). In electricity generation, a generator[ 1] is a device that converts motion-based power ( potential and kinetic energy) or fuel-based power ( chemical energy) into electric power for use in an external circuit. Sources of mechanical energy include steam turbines, gas ...
Induction generator. An induction generator or asynchronous generator is a type of alternating current (AC) electrical generator that uses the principles of induction motors to produce electric power. Induction generators operate by mechanically turning their rotors faster than synchronous speed. A regular AC induction motor usually can be used ...
A permanent magnet synchronous generator is a generator where the excitation field is provided by a permanent magnet instead of a coil. The term synchronous refers here to the fact that the rotor and magnetic field rotate with the same speed, because the magnetic field is generated through a shaft-mounted permanent magnet mechanism, and current is induced into the stationary armature.
Geometric Shapes Extended. Geometric Shapes Extended is a Unicode block containing Webdings / Wingdings symbols, mostly different weights of squares, crosses, and saltires, and different weights of variously spoked asterisks, stars, and various color squares and circles for emoji. The Geometric Shapes Extended block contains thirteen emoji: U+ ...
