nema 23 stepper motor has a simple premise from the user’s point of view: we want to send a series of electronic pulses, each pulse will lead to a change in the specific angle position of the output shaft.
For example, we might want a pulse train consisting of 52 pulses to precisely change the axis angle by 52 degrees.
Accurate incremental segmentation requires precise control and coordination of piston pressure. In this case, the resolution of nema 23 stepper motor system is 1 degree Celsius per input pulse.
Then, through the screw, rack, pinion or other rotary to linear converter, the linear position can be achieved without the need for closed-loop feedback control system.
When the controller is composed of a simple on-off valve system , the resolution of the system is 90 degrees./Pulse (valve shift operation, one at a time).
A more sophisticated electronic control method is needed to achieve so-called micro-stepping. The simple geometric structure of hydraulic nema 23 stepper motor is mainly composed of non-concentric but circular rotor cam and 90 degree angle.
Piston displacement, suitable for sinusoidal and cosine wave excitation, to achieve micro-step and optional continuous rotational motion, with traditional motors. Overall, hydraulic nema 23 stepper motor is very similar to electric nema 23 stepper motor.
