By the end of 1999, the domestic ac stepping motor and its basic self-developed all-digital stepper motor drive success, but relatively lag industrialization, commercialization and mass production ability has not been formed, the domestic demand for precision stepper motor control system is mainly rely on import, such as Japan's mitsubishi, panasonic, Fuji, and Germany's Siemens, etc. In recent years, stepping motor drive and motor products has entered the stage of industrialization, but also mainly concentrated in the numerical control machine tool industry, in more than 400 w power specifications, not form a full range of specifications and standards for the entire automation industry products. Due to China as a manufacturing power, in addition to the CNC machine tool industry, other industries increased year by year, demand for all kinds of stepping motor to do this, step motor manufacturers abroad in succession plans or already in the domestic set up wholly owned factories, use of local resources and cheap labor, batch production of various specifications of the stepper motor products. Domestic design and manufacture technology of step motor are perfect, at present mainly toward standardization, seriation, scale development direction, can only have a certain scale of high reliability and low cost and competitive products. But domestic stepper motor full digital drive technology is still relatively backward, mainly confined to the lack of practical motor digital control algorithm and the high reliability of power module, which greatly limits the promotion of domestic stepper motor. the main products: stepper motor, brushless motor, servo motor, stepping motor drive, brake motor, linear motor and other kinds of models of the stepper motor, welcome to inquire.
