ỨNG DỤNGSP HYDRAULIC VG được khuyên dùng cho các hệ thống truyền động thủy lực tải trọng trung bình,dùng cho các hệ thống cần cẩu, ben, hệ thủy lực xe, các hệ thống tuần hoàn công nghiệp[r]

A two-phase bifilar-wound hybrid step motor is wound with two windings or one center-tapped winding per pole. A positive current in one center-tapped winding will cause the magnetic flux to align in one direction, while a positive current in the other half of the winding causes the flux to align in[r]

Electric motors (electromagnetic actuators) are the most common type of actuators in robots today. They are used even for heavy robots for which some years ago hydraulics was exclusive. This can be justified by the general conclusion that electric drives are easy to control by means of a comp[r]

NEW PROCESSES EXPAND CHOICES FOR RAPID PROTOTYPING
New concepts in rapid prototyping (RP) have made it possible to build many different kinds of 3D prototype models faster and cheaper than by traditional methods. The 3D models are fashioned automatically from such materials as plastic or p[r]

Because ion pumps contain no pumping fluid, they add FAR less contamination to a vacuum than the best diffusion pumps.[r]
