Is the stepping motor on the printer two-phase?There are four lines in all.The motor has four lines. How many is it?What drives can be used to drive the chip?
The two-phase motor is assumed:A-B is a winding,C-D is a winding,
Half step operation commutation mode:The first step, ---A flows to BThe second step, ---A flows to B, and C flows to DThe third step, ---C flows to DThe fourth step, ---C flows to D, and B flows to AThe fifth step, ---B flows to AThe sixth step, ---B flows to A, and D flows to CThe seventh step, ---D flows to CThe eighth step, ---D flows to C, and A flows to B
Whole step switching mode:The first step, ---C flows to D, and A flows to BThe second step, ---A flows to B, and D flows to CThe third step, ---D flows to C, and B flows to AThe fourth step, ---B flows to A, and C flows to DThe first step --- seeChange the direction, press the order from bottom to top.
