Tessitore has published over 80 papers and has given more than 120 lectures at different national and international meetings on topics relevant to spine diseases. Tessitore has significant clinical expertise in performing spinal surgical procedures for degenerative diseases, tumors, deformity, infection and trauma.ĭr. He’s been trained in Naples (Italy) and then moved to Geneva, where he completed the residency program. He is Co-Director of the Cancer Center of Geneva University Hospital and responsible for bone metastasis Tumor Board. They have not been derated.Enrico Tessitore, MD, PD, is the Deputy Chairman of the Neurosurgical Unit at the Geneva University Hospitals in Switzerland, and he is Privat Docent at the Medical School of the University of Geneva. The pounds pull of the smaller magnets as shown on the Small Flat-Faced Electromagnets and the Small Bipolar Electromagnets pages are the actual ratings. When tubing, rounds, or odd shapes must be lifted, the de-rating of the magnet may have to be as much as 75%. This plate is thick enough so that magnetism cannot be detected on theopposite side of hte plate.
These ratings are established by applying force on the magnet under registered tension until the magnet is pulled from a flat, mild steel test plate. Lifting Capabilitiesįor standard Magnetool Lift Magnets have been derated 50%. Two or more magnets on a spreader bar or “H” frame may be needed to eliminate “peel off”. Magnets to pick up thin gauge, flexible sheet, such as 1/8″, 3/16″, and 1/4″ thick, may require variable power, multiple coil or special poles to maintain holding power and prevent double sheet pickup. Of all magnets powered by a single rectifier must not exceed wattage rating of the rectifier, e.g., from one to five 3-watt magnets can be used with a 15-watt rectifier. A rectifier is required to convert 115, 230, or 460 VAC to 115 or 230 VDC. Another method of obtaining direct current for magnet operation is through the use of 12 volt batteries. They will require a rectifier to convert 115 VAC to 12 VDC. It shows the effect of air gap on the holding power of each. The chart below compares the EM-476 flat-faced magnet and the BP-1601 bi-polar magnet. The greater the gap, the further the magnetic lines of force must reach. Scale, rough surface, or nonferrous material between the magnet and work piece create an “air gap”. When work surface is not flat and smooth the magnet cannot make close contact. Use the bi-polar type when the magnet has only partial contact with the work piece, handle an irregular shape or when it must work through an air gap. Has two widely spaced poles or lifting surfaces which cause the magnetic field to “reach out” further. This design usually requires less over-all height and is less expensive.
Used when the entire face of the magnet is in direct contact with the work to be held or lifted and the work surface is smooth and flat. Two basic types of electromagnets are available: flat-faced and bipolar. The economical pickup and transfer of small parts or scrap require a scrap yard type magnet or a magnetic conveyor.Or sketches, parts, polaroid shots, digital images and whatever other information will help in selecting the proper magnet.Will magnet be turned on & off, manually or automatically? If the latter, how many times per minute?.Will magnet be on 100%, 50%, or 25% of the time?.Temperature in which the magnet will operate and temperature of the work.Hot or cold rolled steel, tool steel, high carbon content steel, nickel, carbide, etc.Distance from work surface to face of magnet, whether actually air or non-ferrous material.
LAYAUTO VS MAGNET PLUS
Give thickness, width, length and weight, plus area of contact for the magnet.Is it scaly, rough, flat, machined or of irregular shape?.To help you get the best magnet for your application, we should have the following information: There are many variables that must be considered in the selection of a proper magnet.
