Abstract
The invention relates to a micro stepping motor without pulsation, comprising a casing body set, a stator set, a rotor set, and a spring element. The stator is disposed in the casing body set and the rotor set is contained in the stator set with a driving shaft at where a magnet is firmly disposed. The two ends of the driving shaft are rotatably disposed at the casing body set via an end-shield bearing and a bottom-plate bearing separately. The spring element is disposed as a sheath of the driving shaft and withstands between the end-shield bearing and magnet. By means of this, the spring element could provide elastic force to allow the driving shaft to certainly withstand the bottom-plate bearing, so as to efficiently improve the vibration and noise caused by that the driving shaft unusually hits the bottom-plate bearing.
