_ ndfeb strong magnet manufacturers
Today is quartz watch stepper motor magnets, including its use of material, size, magnetization, and the surface treatment and so on.
Micro precision magnet picture quartz watch stepper motor with ndfeb magnet steel usually used samarium cobalt material, using a thin ring magnets, magnetic steel specification diameter at 0.
2 mm, inner diameter 0.
6 mm, height of 0.
About 6 mm.
Radial magnetization, the use of samarium cobalt magnet surface not plating, ndfeb nickel plating or send gonadorelin.
Quartz watch why apart will excitation-loss stepper motor?
In a nutshell, it related to the characteristics of magnetic materials.
Stepper motor is strong magnetic, magnetic field intensity, the high performance, the better, can have more strong will to how strong, so manufacturers are using high magnetic field intensity (ndfeb magnet
Summary of maximum magnetic energy product ferrite (
More than ten times!
, give it to the magnetic saturation, the once open magnetic circuit closed, no longer & other;
Magnetic weakening & throughout;
Of the amplitude is quite big, big to just pay attention to the point of it is easy to find.
About excitation-loss repair, almost no way under the condition of amateur, need special equipment.
