nema 23 stepper motor decomposes a complete rotating process into hundreds of independent steps, which makes them ideal tools for precise motion control, whether in automobiles, robots, 3D printers or CNC machine tools.In DIY projects, 3D printers and small CNC machine tools, most of the stepper motors you will encounter are bipolar, two-phase hybrid stepper motors, 200 steps per turn or higher resolution, 400 steps per turn. This leads to a step of 1.8 degree angles of 0.9 degrees.
To some extent, steps are pixels of motion. Usually, a given physical resolution is not enough. In the full step mode, hard switching of the coil (wave drive) of the stepper motor will cause the motor to jump from one step position to the next step position, resulting in overshoot, torque ripple and vibration.In addition, we also want to improve the resolution of nema 23 stepper motor in order to get more precise positioning. Modern nema 23 stepper motor drive has the characteristics of micro-step. This driving technology can squeeze any number of micro-step into every complete stepper motor of the motor. It can significantly reduce the vibration and (it is said) improve the resolution and accuracy of the stepper motor.
On the one hand, the micro step is actually the step of nema 23stepper motor, even under the load. On the other hand, they usually do not increase the positioning accuracy of nema 23 stepper motor.
