The principle of Customized stepper motor driver
Simply speaking, stepper motor driver according to the external pulse, through its internal logic circuit control stepper motor windings in a certain order, so as to achieve its operation. Two-phase 1.8-degree stepper motor, for example, is mainly divided into four-line (bipolar) , six-line (unipolar) two ways: line (bipolar) motor, when its winding direction of power in accordance with AC-& GT; BD-& GT; CA-& Gt; db Four State Cycle Change For each change, the motor moves one step, or 1.8 degrees. 6-wire (unipolar) motor, when its winding direction of power in accordance with the order of OA-& GT; Ob-& GT; OC-& Gt; Od Four State Cycle Change, each change, motor operation step, that is 1.8 degrees. The above is only a principle of the introduction, the actual operation will have a lot of complex cases, the corresponding control methods also have a lot of, if you need special help, you can contact the company.
