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 the commutator action (which periodically reverses current direction) or due to electronic commutation, as in brushless DC motors.

2023年6月18日 · What is an Armature? An armature is the component of an 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…

2023年6月18日 · DC Generator Definition: A DC generator is an electrical device that converts mechanical energy into direct current (DC) electricity through electromagnetic induction. Construction of a DC Generator: Key components include the yoke, poles, field winding, armature, commutator, brushes, and bearings.

2013年3月20日 · The armature winding of a DC motor is attached to the rotor, which faces changing magnetic fields during rotation, causing magnetic losses. To reduce these losses, the rotor is made of an armature core composed of laminated silicon steel sheets.

2020年4月21日 · Learn how a DC motor works to understand the basic working principle of a DC motor. We consider conventional current, electron flow, the winding, armature, rotor, shaft, stator, brushes, brush arms, terminals, emf, electromagnets, magnetic attraction as well as detailed animations for how the dc motor works.

An armature can be defined as an power generating component in an electric machine where the armature can be a rotating part otherwise a stationary part in the machine.

Major parts (components) of a DC motor. Field Frame or Yoke. In a DC motor, the field frame, or yoke, carries the field poles and also provides a magnetic path between poles. Since a material of high magnetic permeability is required, cast iron or steel is often used.

2018年9月19日 · Armature core is a cylindrical drum mounted on the shaft. It is provided with large number of slots all over its periphery and it is parallel to the shaft axis. Armature conductors are placed in these slots. Armature core provides low …

2024年10月22日 · DC voltage is applied to the armature windings through carbon brushes which ride on the commutator. In small DC motors, permanent magnets can be used for the stator. However, in large motors used in industrial applications the stator is an electromagnet.

2023年3月17日 · A DC motor’s armature is a cylinder of magnetic laminations that are individually insulated. The armature is perpendicular to the cylinder’s axis. The armature is a rotating component that spins around its axis & is separated from field coil by an air gap.
