genuine leadshine stepper motor 42hs03 step motor current 1 a nema 17 with 0.34 n.m torque better quality

the stepping motor is limited by its own manufacturing process. for example, the step angle is determined by the number of rotor teeth and the number of running s, but the number of rotor teeth and the number of running s are limited, so the step angle of the stepping motor is generally large and fixed, step-by-step resolution, lack of flexibility, vibration at low frequencies, and higher noise than other micromotors, making physical devices susceptible to fatigue or damage.
