The dc generators and dc motors have the same general construction. In fact, when the machine is being assembled, the workmen usually do not know whether it is a dc generator or motor. Any dc generator can be run as a dc motor and vice-versa. In this article, we will explain the con...
A DC machine is an electromechanical energy alteration device. Theworking principle of a DCmachineis when electric current flows through a coil within a magnetic field, and then the magnetic force generates a torque that rotates the dc motor. The DC machines are classified into two types such a...
Case 2595CAPACITIVE BRUSH CONSTRUCTION FOR A DC MACHINEABSTRACT OF THE DISCLOSURE\nA brush arrangement for use in a DC dynamo-\nelectric machine to reduce the sparking which can occur\nat the trailing edge of a brush as it leaves a commutator\nsegment. The main brush portion has affixed to ...
The poles and field winding are the stationary parts of a DC generator that produce the main magnetic field in the machine. They are bolted to the inner periphery of the yoke. The poles are made of laminated sheet steel or solid cast iron or steel. The laminations reduce the eddy current...
Check Construction and Quality of Build –“Things That Can Go Wrong” Although not a thing that could go wrong, it is prudent to stress that the methodology which is the basis of this handbook is based on the premise that the construction group and the commissioning team work as a cohesive...
To support this system, we have developed an automated crawler that permits the establishment of a bank of relevant pages, adapted to the needs of this particular industry-user community. It is based on the machine-learning framework in which an intelligent decision unit is trained to distinguish...
The paper makes use of a recently developed total cost of ownership (TCO) methodology to assess the cost competitiveness of the best-selling battery electric vehicles (BEVs), hybrid electric vehicles (HEVs), diesel and petrol cars in Nor... M Scorrano,TA Mathisen,M Giansoldati - 《Economics...
The construction industry is a particularly attractive industry for nanotechnology applications. Since it employs a diversity of building materials, nanomaterials can be employed to enhance the materials’ performances, durability, longevity and sustaina
This invention relates to an arrangement for communicating fluid between a pressurized source and an implement that is remotely mounted on a linkage arrangement of a construction machine. The conduit arrangement includes a pair of conduits positioned internally within the linkage arrangement. One conduit...
