Armature meaning in physics

An armature is defined as the component of the electric machine (i.e. a motor or generator) that carries alternating current (AC). The armature conducts AC even on DC (Direct Current) machines via the commutator (which periodically reverses current direction) or due to electronic commutation, (e.g. in a brushless DC motor) The part of an electric motor or generator that consists of wire wound around an iron core and carries an electric current. In motors and generators using direct current, the armature rotates within a magnetic field; in motors and generators using alternating current a magnetic field is rotated about the armature Armature definition is - an organ or structure (such as teeth or thorns) for offense or defense. How to use armature in a sentence In electrical engineering, an armature is the component of an electric machine which carries alternating current. The armature windings conduct AC even on DC machines, due to the commutator action or due to electronic commutation, as in brushless DC motors. The armature can be on either the rotor or the stator, depending on the type of electric machine. The armature windings interact with the magnetic field in the air-gap; the magnetic field is generated either by permanent.

Coil span (also known as coil pitch) is defined as the peripheral distance between two sides of a coil, measured in terms of the number of armature slots between them. That means, after placing one side of the coil in a particular slot, after how many conjugative slots, the other side of the same coil is placed on the armature of the armature, so one side is pushed while the other is pulled. This makes the armature rotate. After the armature has rotated through half a turn (180°), then the side of the armature being pushed upwards in the above picture is now on the left and the side being pulled down on the right. The armature would be trying to turn in the opposite. Armatures — Blender Manual

What is an Armature? (In An Electric Motor & Generator

armature, in art: see sculpture sculpture, art of producing in three dimensions representations of natural or imagined forms. It includes sculpture in the round, which can be viewed from any direction, as well as incised relief, in which the lines are cut into a flat surface It works with all available object types for skinning (meshes, lattices, curves, surfaces and texts). It is based on proximity between bones and their geometry, each bone having two different areas of influence, shown in the Envelope visualization Generator Physics. A generator is simply a device that moves a magnet near a wire to create a steady flow of electrons. The action that forces this movement varies greatly, ranging from hand cranks and steam engines to nuclear fission, but the principle remains the same Acceleration is the measure of the change in velocity over time. The change in velocity can be a change in speed, direction or both.The formula for average a.. Definition: The armature reaction simply shows the effect of armature field on the main field. In other words, the armature reaction represents the impact of the armature flux on the main field flux. The armature field is produced by the armature conductors when current flows through them. And the main field is produced by the magnetic poles

  4. Figure 2. A simplified diagram of an AC generator. The right half of the armature is moving left, while the left half is moving right. Therefore, the electromotive force on the right side is directed towards the near end of the armature, and the force on the left side of the armature is directed towards the far end of the armature. This allows a current to flow through the loop, as electrons.

These are only two of many examples of pressures in fluids. Pressure P is defined a One of Heidegger's clearest statements of what he means by enframing appears in his discussion of the dilemma of modern physicists, who are discovering that that the physical world does not lend itself to measurement and observation as readily as they once thought. Physics, Heidegger argues, is bound to a particular way of looking at the world

Things do get pretty hairy when you need a description that's both quantum and relativistic, which is the regime of high-energy physics Losses in DC machines (motor and generator) include friction, windage and electrical losses. Friction is present in all rotating machinery.

The number 137 (also called the fine structure constant) holds the answers to the Universe - or so suppose famous physicists like Richard Feynman, who once called it one of the greatest damn. It means that when we go to calculate simple processes, such as two electrons scattering off one another through the exchange of photons, we only need to consider the simple case of one photon exchange -- every additional photon you consider is less important by a factor of 1/137 The more we learn about the universe, the more questions seem to arise.

What is a commutator? - Motion Control Tip

In a DC machine, two kinds of magnetic fluxes are present; 'armature flux' and 'main field flux'.The effect of armature flux on the main field flux is called as armature reaction. MNA and GNA EMF is induced in the armature conductors when they cut the magnetic field lines. There is an axis (or, you may say, a plane) along which armature conductors move parallel to the flux lines and, hence. That means, when supply voltage V and the armature resistance R a are kept constant, then the speed is directly proportional to armature current I a. Thus, if we add resistance in series with the armature, I a decreases and, hence, the speed also decreases. Greater the resistance in series with the armature, greater the decrease in speed. 3

pay (or not) according to their means. Nevertheless, I am hoping that students who truly find this work useful will purchase a copy through Lulu or a bookseller (when the latter option becomes available), if only to help subsidize me while I continue to write inexpensive textbooks in physics or other subjects Physicists Are Philosophers, Too. In his final essay the late physicist Victor Stenger argues for the validity of philosophy in the context of modern theoretical physics A New Physics Theory of Life. A physicist has proposed the provocative idea that life exists because the law of increasing entropy drives matter to acquire life-like physical propertie When the armature rotates, the change in magnetic flux increases and the induced current increases until its maximum value at the horizontal position.
