2018-3-8Linear motors can achieve very high velocities up to 15 ms with a trade off in force for ironcore motors as technology becomes limited by eddy current losses. Linear motors achieve very smooth velocity regulation with low ripple. The performance of a linear motor over its velocity range can be seen in a force-speed curve as shown opposite

2016-2-3TREATMENT MACHINES FOR EXTERNAL BEAM RADIOTHERAPY 125 Photons with energies ranging from ero to the kinetic energy of the incident electron may be produced resulting in a continuous brems-strahlung spectrum The bremsstrahlung spectrum produced in a given X ray target depends on the kinetic energy of the incident electron as well as on the thickness
2018-1-1The global construction sector creates 315 million tons direct CO 2 emission representing 5.5 the total CO2 emission of this sector. 99.5 of the direct energy use in the global construction sector are fossil fuel. This fossil fuel is mainly used for the on-site construction operation specially the operation of construction machines and
What is less obvious of course is the enormous amount of manpower used to build these marvels for in an age of few machines it was largely manpower that had to do all the work. This set is a depiction of those men. In a society that had large numbers of slaves it is no surprise that slaves provided much of the hard manual labour in construction

Road construction equipment are found in a wide variety ranging from the very heavy equipment to portable and lighter equipment. These modern and high construction equipment make the construction job easier and quicker. Also the work done my heavy machinery is of good quality this is the reason that we find a wide variety of equipment at every construction site
It is the outer body of the motor. Its main function is to support the stator core and to protect the inner parts of the machine. For small machines the outer frame is casted but for the large machine it is fabricated. The figure below shows the stator construction. Stator Core. The stator core is built of high-grade silicon steel stampings

This paper analyses and calculates two dimensional electromagnetic fields in permanent magnet linear synchronous machines PMLSMS by finite element method. According to the field distributions in no-load and load operations the methods of calculating the thrust and vertical force in a single-sided PMLSM are presented. Fields and forces determined by the finite element method are good

Throughout this book we will refer to learning machines using hypotheses that form linear combinations of the input variables as linear learning machines. Importantly we will show that in most cases such machines can be represented in a particularly useful form which we will call the dual representation
