magnetic clutch

Magnetic clutch and brake, is a means of powder produced by a special process to transfer and control torque (tension) of the new electromagnetic clutches and brakes. It has a friction type, style, etc. rodent magnetic devices models are not good, can be widely used to start, stop, couplings, clutch indexing, jog, soft start, overload protection Care, fuck away protection, brake, tension control, brake and other mechanical transmission buffer, in order to provide a new generation of mechatronic control unit acting. 
Principle: The main components of the magnetic powder clutch parts can be divided into stationary and rotating parts. Stationary part from the base, the excitation coil and other components; coupled driving side rotating part by The measuring cylinder and driven coupling of the magnetic drums rotor and other components. The cylinder tube in the air gap between the rotor and the magnetic powder is placed, connected to control power production of the excitation coil 

magnetic systems

magnetic systems: China material magnetic phenomena and application of magnetic materials in the country was the first to discover the world. magnetic tubes Early in the Warring States period magnetic systems . In Eleventh Century invented the method of producing artificial permanent magnetic material. In 1086 the "dream" record of making and using the compass. From 1099 to 1102 with a compass for navigation of the account, it is also found that the geomagnetic declination phenomenon.In modern times, the development of the electric power industry to promote the development of metal magnetic material -- wet magnetic separator.magnetic rods The main magnetic path of the magnetic circuit along a closed circuit is formed is set, the air-gap magnetic powder rapidly formed along the magnetic air gap solid chain, through its binding, the link cylinder and  A rotor, in order to achieve torque transmission, the magnetic flux after power-off moment disappears rapidly solidified powder of the disintegration under the action of the centrifugal force, squeezed in the inner cylinder

Torque change with a linear relationship between the excitation current, so that by adjusting the excitation current can be accurately controlled amount of torque, and can show a very good reproducibility. smco magnets Its Error is not less than 5%. Second, to achieve precise control of torque Output torque corresponding to a current value, but independent of the speed, by adjusting the excitation current values can be kept constant torque output of the torque value can be freely changed. Third, the torque rises rapidly, the rapid response As a result of the special non-saturated magnetic circuit design magnetic devices and tiny spherical powder, the magnetic flux generated by the coil in an instant (0.005 to 0.01) and work as an effective magnetic flux Therefore the torque response, and excellent response. Four, suitable for continuous use slide Using tiny wearable spherical powder as torque transmission medium, and even very small friction heat and thermal performance excellent, plus a reasonable heat dissipation structure and a variety of side Type, so the allowable allowable coupling power and coupling power and allowable slip power, when used in continuous sliding devices without worrying about overheating and burning. Five, small size, light weight, long life Compact structure, small size, and weighs only other products of the same type torque 2/5, while using the magnetic properties, wear resistance, corrosion resistance, heat resistance and good 

The history of the magnet

5,000 years ago, humans discovered natural magnet (Fe3O4), 1990 atomic gap -Sm-Fe-N magnets come. 1991 German physicist put forward a theoretical basis EF Kenei Le Duplex composite magnet exchange interaction, pointing out the prospects for the development of neodymium block magnet. With the development of society, more and more widespread application of the magnet, from high-tech products to the most simple packaging magnetic, currently the most widely used or NdFeB magnets and ferrite magnets. From the history of the development of the magnet, the turn of the century, people mainly use carbon steel, tungsten steel, chrome steel and cobalt permanent motor magnets for steel.
