About motor magnets off the installation method of skills

Many netizens about electric motor magnets off a series of problems brought by disturb, the magnet manufacturer xiaofu compiled about motor magnets fall off some of the problems and installation techniques, hope to help you! Falls off a net friend asked, magnetic steel, rotation, installed electric found again slowly and over current light normally on what's going on? This may be when you're installing magnet steel magnet polarity opposite to cause, it is possible that the motor water rust, rust are very easy to be magnetized, become a magnet, the motor magnetic steel rust not clean, can cause mutual interference between the poles, the lines of magnetic force chaos, cause no force. After cleaning better! What kind of glue stick magnetic steel used? How does it work? AB glue can stick the magnet steel! There is no coating but you'd better! If there is a coating prepared with bonding surface of sand paper burnish, including the motor rotor, then put and magnetic tile to bonded joint surface with carbon tetrachloride degreasing, air-dried and adhesive! Forget to say AB glue is elder brother! Should be A call B tube so AB glue! All motor magnets off pack N pole and S pole first? Don't need to find the location of the first piece of magnet steel, actually also does not have the first piece. Order it doesn't matter, will be subject to convenient installation, as long as the guarantee of adjacent two pieces of the opposite polarity. Also have a net friend added: brush motor has magnetic steel and carbon brush the relative position of the two have strict requirements, magnetic steel interval between each other should be uniform. Otherwise it will affect the efficiency of the motor and commutation spark. Usually the first piece of magnet steel center line and two carbon brush center should overlap. As for is N and S should be no problem. Most found that reverse the motor after it is ok to swap the inlets. Within the outer magnetic rotor magnet steel N, S pole is alternant distribution, and they each slice is arc, don't tell anyway, just tell direction, according to the original do mark, paste leveled consistent with other magnets, not highlight or dislocation, in order to make sure the air gap of the motor and mechanical dimensions are not affected. Why magnetic steel will fall off? Why? What are those? 1, overheating. 2, process stability. 3, viscose, maybe glue quality problems. 4, Mosaic is not strong. Articles about motor magnets off the installation method of collection techniques by Ricky magnet card manufacturers xiaofu share, the company's main all kinds of radial multipole rotor, motor magnetic tile machine, injection molding magnetic, special-shaped neodymium magnets, etc. Guess you attention related motor magnetic steel articles; How to avoid damage to the permanent magnet motor magnetic steel?
