Can a stepper motor be opened?

time:2014/11/5 10:47:01 click:1406times

No, because when the stepper motor is opened, the rotor makes contact with the stator and the magnetization is reduced. As a result, the torque of the motor will decrease appreciably. This primarily affects magnets with a lower coercive field strength, such as Alnico magnets, that are easily shifted from their optimum working point in their nonlinear magnetization curve and thus pass through a weaker magnetization characteristic. Higher-quality N magnets, on the other hand, splinter very easily without appropriate tools and are easily cracked by only slightly incorrect handling and can therefore sustain permanent magnetic damage.
