Recently we met customers to ask how to judge the motor magnetic tile demagnetization problem, and just take this opportunity to talk to you, what change will motor magnetic tile demagnetization have, and how do we determine? In the following cases, we should pay attention to whether the motor magnetic tile demagnetization.
Motor magnetic tile is mainly used in a variety of motors, so it is known as motor magnetic tile, which is used in a variety of motors such as: servo motor, electric vehicle, brush motor, brushless motor, motorcycle starting motor, energy-saving motor, motor and so on.
ⅰ.Sintered Ndfeb magnetic tile, which is mainly used for some high-performance motor.
ⅱ.Ferrite magnetic tile.
ⅲ.Bonded Ndfeb magnetic tile.
ⅳ.Samarium cobalt magnetic tile.
ⅰ.If you find that the no-load current increases, and the speed of the motor magnetic tile is much faster than usual;
ⅱ.When the motor magnetic tile is operating, the current increases and the no-load speed becomes higher;
ⅲ.If the motor magnetic tile speed is unchanged, but the voltage becomes smaller;
ⅳ.The Tesla meter measures the magnetic field, and the two motor magnetic tiles are compared, and the gausses at the center point of the demagnetization motor will be different;
ⅴ.During the demagnetization, the no-load speed becomes high, torque becomes low, and current becomes large;
ⅵ.Comparing two motor magnetic tiles, no-load speed of demagnetization of the motor will be much faster, and the sound of operation will be different.
Motor magnetic tile rust is not uncommon, as long as the equipment is in a relatively high humidity environment, it is easy to encounter this situation. But many people do not know how to deal with it better, for fear that the motor is damaged. In fact, there is no need to fear the motor magnetic tile rust, the method of cleaning it up is also very easy.
ⅰ.You can use a wet towel to scrub, and then take a dry towel to wipe clean;
ⅱ.You can sand the rusty place with sandpaper, and then blow off the rust with an air pump;
ⅲ.You can use sandpaper to polish the rusty place, with tape to stick the rust off is also possible;
ⅳ.You can also use an Angle grinder to clean the rusty place of the motor magnetic tile, and the cleaning ball can be used to clean the motor cover.
