【Abstract】 The subdivision has been widely used as method to improve the differentiation of stepping motor.In this paper,a system of subdivision driver method based on MSP430F149 was presented,through adopting the method named "Current vector even rotation with uniform amplitude".By selecting reasonable subdivision current wave form of phase winding for stepping motor,the technology of division was improved to a new level.The result indicated that the drive system featured highly precise division and smooth operation low noise and power consumption,as well as reliable and effective.更多还原
