A stepped motor which could convert an electric pulse signal into an angular displacement or linear displacement and its driver circuit diagram.
A stepping motor is an open-loop control element stepping motor that converts an electrical pulse signal into an angular displacement or a linear displacement. In the case of non-overload, the speed and stop position of the motor only depend on the frequency of the pulse signal and the number of pulses, and are not affected by the load changes. When the stepper driver receives a pulse signal, it drives the stepper motor to rotate a fixed angle in the set direction, called "step angle", and its rotation is performed step by step at a fixed angle.
It is one of the most commonly used control components in industrial control and instrumentation. It has the characteristics that the input pulse is proportional to the motor shaft. It is widely used in intelligent robots, floppy disk drives and data machine tools. The most suitable system for microcomputer-controlled stepper motors is the 20BY-0 stepper motor. It uses a +5V DC power supply with a step angle of 18 degrees and the motor coil consists of four phases.
