| Abstract: | A system of division driver method based on Tms320F2806 was proposed.Through adopting the methodnamed Current vector even rotation with uniform amplitude,the system featured highly precise division.The hard-ware system for two-phase hybrid stepping motor was developed.The high-precision hall current sensor was appliedfor feedback unit to sample the winding current.The regulation algorithm of closed-loop current of control system wasalso realized in the end,and a large amount of experiments were carried on.T... |
