Research and manufacture of stepper motor, as in China started in the late 50 s of this century, the late 50 s to 60 s, dominant are institutions of higher learning and scientific research institutions for the study of some devices used or developed by a small amount of the product. During the cultural revolution in China began to mass production and application of the stepper motor, like in jiangsu, zhejiang, sichuan, Beijing, nanjing, has been put into production around the state, have also been put into use in various industries, including driving circuit of the majority of semiconductor devices basic implementation localization, at that time the whole logic operation circuit, composed of discrete components, as well as the capacitance coupling input counter, trigger, circular allocator.
At present, the manufacturer of stepper motor is many, but has the professional and technical personnel, can be developed, developed at the factory is very scarce, most manufacturers only one to twenty people, even the most basic equipment.
Drive high-power industrial equipment abroad, basic does not use linear stepper motor with high torque, from the power circuit of the cost, efficiency, noise, acceleration, absolute speed, the system inertia compared with maximum torque ratios, or not cost-effective, adopts dc motor, motor encoder high overall technical and economic indicators. The domestic large torque stepper motor is used to realize the numerical control machine tool, now has the strength of enterprise adopts ac motor drive nc machine tool, in driving equipment, the main gap in overseas for ac motor control theory and engineering analysis, application ability is strong, advanced control theory as the software, compiler inside the controller.
