Abstract
Introduction step enter electric motor of development history, and local present condition and step enter electric motor future of application foreground.And elaborated a step to enter electric motor to turn soon, angle, turn Ju of control principle.This text elaborated a kind of step enter electrical engineering controller of design project, and drew principle diagram and PCB plank diagram, composed a procedure source a code.Realization to step enter the electric motor turn soon, angle of control, and completion real object of creation.This period main usage the protel 99 se the software draw principle diagram and make plank, usage proteus 7.1 softwares carry on an imitate of procedure code true with the theories of the function verification.The end experiment certificate procedure a code through an adjust of hardware of actual function, completion design controller.
