Principle of stepping motor subdivision the stepping motor subdivision control in essence is through the current in the stator winding of stepping motor control, to the synthesis of stepping motor, a magnetic field according to the requirements of some changes, so as to realize stepper motor step Angle of segmentation. The best way of segmentation is constant torque step from the Angle of subdivision, etc. Under normal circumstances, the synthesis of magnetic field vector amplitude decide the size of the motor rotation torque, the Angle between the adjacent two synthesis of magnetic field vector size step determines the size of the pitch Angle. To produce nearly uniform circular in the motor rotating magnetic field, the synthesis of each phase winding magnetic field vector, namely the resultant vector of each phase winding current amplitude constant rotation movement should be done in space, this would require the sinusoidal current in each phase winding phase zhongtong.
