1.2 degree stepper motor meaning :
The number of steps/lap == is actually the number of steps used by the stepper motor to walk one lap.
You look at the breakdown of others’ drive steps/laps. In fact, the relative is a few subdivisions.
Like what. 200 steps/lap, which means that it takes 200 steps to walk a circle. 1 step is 1.8 degrees.
If it is a two-phase stepper motor. This 200 steps/lap is no subdivision. It’s a whole step to go.
Because the 1.8 degree angle is the basic step angle of the two-phase stepper motor.

If you turn it up to .2,000 steps/lap, it takes 2,000 steps to walk a lap. Walking 1 step is 0.18 degrees.
Because the basic step angle of the two-phase stepper motor is 1.8 degrees, and now walking 1 step is 0.18 degrees.
That is, 1.8/0.18=10, and this 10 is a 10 subdivision.
When you tune to 2000 steps/lap it is quite subdivided with tuning to 10.
Explanation of the original and function of stepper motor driver subdivision
Stepper motors are widely used in electronic equipment, textile equipment, medical equipment, advertising equipment and other fields.
The stepper motor and the stepper motor driver constitute the stepper motor drive system.
The performance of the stepper motor drive system depends not only on the performance of the stepper motor itself, but also on the advantages and disadvantages of the stepper motor driver.
The study of stepper motor drives was carried out almost simultaneously with the study of stepper motors.
A stepper motor driver is an actuator that converts electrical impulses into angular displacement. When the stepper driver receives a pulse signal, it drives the stepper motor to rotate a fixed angle (called “step angle”) in the set direction, and its rotation is run step by step at a fixed angle.

The amount of angular displacement can be controlled by controlling the number of pulses, so as to achieve the purpose of accurate positioning; At the same time, the speed and acceleration of motor rotation can be controlled by controlling the pulse frequency, so as to achieve the purpose of speed regulation and positioning.
Widely used in engraving machines, crystal grinding machines, medium-sized CNC machine tools, EEG embroidery machines, packaging machinery, fountains, dispensing machines, cutting feeding systems and other large and medium-sized CNC equipment with high resolution.
The number of phases of the stepper motor refers to the number of coil groups inside the motor, and the commonly used two-phase, three-phase, four-phase and five-phase stepper motors are commonly used.
The number of motor phases is different, and its step angle is also different, generally the step angle of two-phase motor is 1.8 degrees, the three-phase is 1.2 degrees, and the five-phase is 0.72 degrees. In the absence of a subdivision drive, the user mainly relies on the selection of stepper motors with different phase numbers to meet the requirements of the step angle.

If a subdivision drive is used, the phase number becomes meaningless, and the user can change the step angle simply by changing the subdivision number on the drive.
The subdivision of stepper motor drives will make a qualitative leap in the operating performance of the motor, but all this is generated by the drive itself, and has nothing to do with the motor and control system.
When in use, the only point that users need to pay attention to is the change of the step angle of the stepper motor, which will have an impact on the frequency of the step signal sent by the control system, because the step angle of the stepper motor will become smaller after subdivision, and the frequency of the step signal is required to increase accordingly.
1.2° three-phase hybrid stepper motor
Take a 1.8-degree stepper motor as an example: the step angle of the driver is 0.9 degrees in the half-step state, and the step angle is 0.18 degrees in the ten-subdivision state, so that the frequency of the step signal sent by the control system is 5 times that of the half-step operation in the case of the same motor speed.
Generally, the accuracy of the stepper motor is 3~5% of the stepping angle. The deviation of a single step of the stepper motor does not affect the accuracy of the next step, so the accuracy of the stepper motor does not accumulate.
