Orthocyclic winding Orthocyclic wound coil Orthocyclic winding of a round coil Orthocyclic winding of a rectangular motor coil. This type of winding structure creates an optimal fill factor (90.7%) for round wires. The windings of the upper layer need to be placed into the grooves provided by the lower layer.
A helical armature is a form of air-gap electric motor or generator armature wound in a helical fashion as opposed to a conventional random or orthocyclic winding. Such a design is of interest in superconducting motor and generation technology, [1] though comparatively little research has been done on the subject.
A DC armature of a miniature motor (or generator) An example of a triple-T armature 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 rotating magnetic field is the key principle in the operation of induction machines.The induction motor consists of a stator and rotor.In the stator a group of fixed windings are so arranged that a two phase current, for example, produces a magnetic field which rotates at an angular velocity determined by the frequency of the alternating current.
A circuit diagram (or: wiring diagram, electrical diagram, elementary diagram, electronic schematic) is a graphical representation of an electrical circuit. A pictorial circuit diagram uses simple images of components, while a schematic diagram shows the components and interconnections of the circuit using standardized symbolic representations.
A conventional six-winding, grounding transformer or zigzag bank, [1] with the same winding and core quantity as a conventional three-phase transformer, can also be used in zigzag winding connection. In all cases the first coil on each zigzag winding core is connected contrariwise to the second coil on the next core.
The coil winding process and the process of joining the coil and core may be simpler. Since the coils are flat, rectangular copper strips can more easily be used, simplifying high-current windings. It is often possible to make the rotor significantly lighter. Potentially shorter magnetic path length.
The stator consists of multiple projecting (salient) electromagnet poles, similar to a wound field brushed DC motor.The rotor consists of soft magnetic material, such as laminated silicon steel, which has multiple projections acting as salient magnetic poles through magnetic reluctance.
