Armature Definition
Armature definition
1. : the part of an electric motor or generator that produces an electric current when it turns in a magnetic field. 2. : a frame used by a sculptor to support a figure that is being modeled.
What does an armature do?
The function of an armature is multi-purposed. The main role is to conduct current over the field, thus generating shaft torque within an active machine. The secondary purpose of an armature is to produce Electromotive Force (EMF).
What does armature mean in art?
armature, in sculpture, a skeleton or framework used by an artist to support a figure being modeled in soft plastic material. An armature can be made from any material that is damp-resistant and rigid enough to hold such plastic materials as moist clay and plaster, which are applied to and shaped around it.
What do you mean by armature in physics?
An armature is the will wound upon a soft iron core which is suspended such that it can rotate freely. It is a rectangular iron core wrapped by the copper coil through which electricity passes and due to magnetic field it experiences a force and rotates.
What is another name of armature?

Where is the armature in a motor?
A DC motor has coils of wire mounted in slots on a cylinder of ferromagnetic material, which is termed the armature. The armature is mounted on bearings and is free to rotate. It is mounted in the magnetic field produced by permanent magnets or current passing through coils of wire, which are called the field coils.
What is armature of a motor?
An armature is a device through which electric current is passed for generating torque (rotor). The current that passes through the rotor is sometimes called the armature current. The word "armature" refers to a device through which electric current is passed for generating torque.
What are the parts of armature?
An armature is made up of a number of main components; the core, the commutator, the winding and the shaft.
What is the advantage of armature?
1) The current is drawn directly from fixed terminals on the stator without the use of brush contacts. 2) The insulation of stationary armature winding is easier. 3) The number of sliding contacts (slip rings) is reduced. Moreover, the sliding contacts are used for low-voltage DC Source.
What does armature mean in architecture?
Taken on its own, the word "armature" can suggest structural support, e.g. the framework reinforcing a building. Urban armature is in some ways like this because it connotes the tying together of a community or other entity through similar forms and materials.
What is an armature in architecture?
(noun) - In art, an armature is an underlying, unseen, supporting component (usually of wood or metal) for something else.
Do you need an armature?
Yes, making sculptures without an armature is very much possible. But, you need to understand the importance of an armature. Making an armature before sculpting provides more stability and makes the shape of things more solid, yet flexible. It adds more strength and grip to the sculptures.
What is difference between armature and rotor?
So basically, the rotor consists of a field magnet which rotates while the rotor remains stationary and on the other hand the armature carries current and is stationary and part of the stator.
What is armature voltage?
The armature voltage formula is. V = k η ϕ Where k is constant based on armature design, is armature speed in rpm and is flux generated by the magnetic field. However in physical motors, the resistance is distributed from one end of the winding to the other. Armature voltage is the same as terminal voltage.
What is the difference between armature and commutator?
Armature | Commutator |
---|---|
It provides current to commutator from the core of the armature | It changes AC to DC & vice-versa |
It is a set of coils arranged in the core | It is a set of segments |
What is a motor commutator?
What is a Commutator? Commutators are used in DC machines (DC motors and DC generators) universal motors. In a motor, a commutator applies an electric current to the windings. A steady rotating torque is produced by reversing the current direction in the rotating windings each half turn.
What is another word for assemblage?
crowd | gathering |
---|---|
assembly | group |
congregation | company |
flock | mass |
multitude | meeting |
What is the armature in a DC motor connected to?
The armature is connected to a DC power source through a pair of commutator rings. When the current flows through the coil an electromagnetic force is induced on it according to the Lorentz law, so the coil will start to rotate.
What is armature DC?
DC Armature. The armature of an electric machine is the name historically given to the winding where a voltage is induced and power transfer between electrical and mechanical systems occurs. It is a term used in dc machines and ac synchronous machines. In a dc machine, the armature is the rotating circuit.
What is armature core in DC motor?
Armature core: Armature core is the rotor of a dc machine. It is cylindrical in shape with slots to carry armature winding. The armature is built up of thin laminated circular steel disks for reducing eddy current losses. It may be provided with air ducts for the axial air flow for cooling purposes.
