The summary dominates a field in industrial automation and motion, function optimization is affecting the user choice to coder technology greatly. Carry the article, we are wraparound summed up photoelectricity coder, rotate of transformer and magnetism type coder different, elaborated why magnetism type coder is on a lot of application more desirable reason. The article introduces Tiemuken to you at the same time what how coder of company magnetism type uses technology of patent Huo Er effect to obtain precision and reliability in order to help is the biggest change. The introduction is versed in as automation of domain of course of study rapid and outspread, the servo demand with predominant to function market is higher and higher. Industrial automation applies extensively at packing, paper processing, electric power generates electricity etc a few have high temperature, dust, moisture and the special environment that shake strongly. It is effective that photoelectricity coder is used in a few cleaner automation environments to be confirmed by the design with the success, but more reliable feedback operation can adopt a convention only, if the unit program of high cost rotates transformer or the optical coder with be enclosed better are able to come true. The progress of level of technology of magnetism type sensor makes type coder is in magnetism to be bumped strongly, shake and more feasible equipment is become to implement option plan below the environment of contaminant. Photoelectricity, rotate transformer and coder of photoelectricity of technology of coder of photoelectricity of magnetism encode technology are to use grating induction to generate signal. Stable signal often depends on clear, persistent beam of light. The pollution of any material is met block up illuminant causes signal interference and encode invalidation. Divide this beyond, servo can be caused below damp temperature rotate the possibility that piled up dish of condensation that go up to increase be no longer in force thereby. Typical to photoelectricity coder will tell, the air clearance that we require normally lesser, so small span needs to assure the integrality of smooth signal and accuracy. From the point of the result, optical coder is mixed to bumping vibration is very flimsy, this meeting is brought about directly rotate to be piled up solely dish or the attaint of sensor. Traditional solution includes to undertake enclosing to photoelectricity coder, make its are packed solidder. Manufacturer of coder of a lot of photoelectricity tries to make through sealing of product of research and development its are had better resist vibration, bump the function with temperature. Very unfortunate is, these additional protection always cause product volume bigger, cost is higher. Rotate transformer technology photograph to photoelectricity coder, rotate transformer is stabler choice. Do not have typically brush come back change to often be formed by coil of two static states, achieve 90 degrees machinery to differ. The means that structural ability yields with signal character is pressed to change coming back implement creation stability. Although rotate,transformer is avoided almost at sufferring the harm of industrial environment, but the cost that its control a system often compares photoelectricity and magnetism type coder a lot of taller. They need a resolver digital commutator compositive go up to circuit and place in more remote region, such need offer wiring to execute elementary signal. Wiring can increase the complexity of installation, installation is safeguarded rise no-go also. The technology of magnetism type coder with advanced technology of magnetism type coder makes the coder plan of compact, low cost gets apply and developing, the pulse that falls in harsh environment compared with photoelectricity coder is fluctuant, magnetism type coder appears more abiding and durable. Agree in iron Mu company, design of the engineer's will newest magnetism type encode is shirt-sleeve the technical patent application of suddenly Er effect, pile up in fast magnetism thereby dish on win higher precision demand. Magnetism sensor does not need clean and transparent clearance. Magnetism is piled up dish and a few distances need to be able to move only between sensor. Want these clearance to be not contained only iron material cram, magnetism pulse can be detected easily by MPS chip. Bilge, dust, smeary, condensation and other contaminant won't affect the reliability of magnetism coder. Magnetism coder still can defy bump and oscillatory. Compared with photoelectricity coder, sensor and magnetism pile up dish of clearance between to be able to achieve 4mm, and the accuracy that a bit does not affect signal. Magnetism coder can carry clearance to move in the axis, radial and jumpy total public errand is as high as 2. 5mm, this decreased to pile up dish of possibility that bumps attaint with sensor greatly. Timken®The Mu of iron of technology of suddenly Er effect of magnetism type coder agrees the form of technology of magnetism type coder that the company offerred two kinds of economy -- the Timken of the coder design that conformity encloses and individual chip®MPS uniform encoding implement integrated circuit, two kinds of means used technology of suddenly Er effect and very easy compositive in the design plan that has to the client. Timken®M15 is modular the sensor that magnetism type coder is a high accuracy, position and speed, it is gone up to detect in order to use in electric machinery and other machine by wide application buy of position of axle and speed feedback demand. Timken®M15 coder is enclosed and compact connective character makes it is in automation, be in especially a few without brush or have brush servo and small-sized pace to go up into electric machinery get applied extensively. Its can easy to do application deploys the design program of photoelectricity coder to go up at a few existing electric machinery, have to machinery and electronic signal but interchangeability. Except it has rectification as photoelectricity coder beyond this, referenced pulse, the character such as open circuit collector and line drive output. Conclusion the photoelectricity coder compared with the tradition, magnetism type coder is in endurance, dependability, compact enclose a design to go up to have a lot of advantages. It is especially below a few moisture, high temperature and the severe exacting environment that shake strongly more applicable. shirt-sleeve the magnetic coder of suddenly Er technology takes system of lighting of electric machinery automation in the pace, the Schneider MDrive® driver of industrial automation system has successful and wide application. Technology of sensor of magnetism of abaxial of this new generation is applied in car motivation to turn to system, pace to take electric machinery drive, mine car by successful ground, the transmission sensor that measures system of equipment of system, medical treatment, lighting and cross-country equipment to go up. When choosing a proper coder application technology, engineers need to consider an environment, enclose, precision and cost demand. In the situation that has particular demand to function, coder often cannot be developed optimum behavior by the effect that manipulates an environment, and just of technology of magnetism type coder can satisfy a client such demand, and cost is relative more cheap.
