The traditional purifying method of the organic semiconductor material in laboratory is time-consuming,effort-consuming and money-consuming. In this paper,a design scheme of motion control system of small equipment which is based on DSP using for organic semiconductor melting is proposed. The system takes TMS320LF2407A as the main chip,by cascading two pieces of L298N,the driving capability is increased. Simultaneously,by using software micro stepping driving technique,the stepping motor moves slowly and steadi-ly. Anthraquinone mixture is used in purification testing. The results show that this motion control system meets the requirements of the small melting equipment and realizes the automation of zone melting equipment. In addition,it provides a new idea of designing and stud-ying melting equipment.
