NEMA 23 57MM GEARBOX STEPPING MOTOR-HOLRY

General technical characteristics:
1. The stepping motor is used in low-speed occasions---the speed does not exceed 1000 revolutions per minute, (6666PPS at 0.9 degrees), preferably between 1000-3000PPS (0.9 degrees), and it can be used here by a decelerating device. At this time, the motor has high working efficiency and low noise;
2. The stepping motor is best not to use the full-step state, the vibration is large in the full-step state;
3. The voltage value in the motor specification is not the driving voltage volt value. The specific driving voltage can be selected according to the stepper driver (recommendations: 42 and below motors use 12-24V, 57 motors use DC 24V-48V, 86 use DC 48-80V, 110 motor adopts higher than DC 80V)
4. For loads with large moments of inertia, a large frame size motor should be selected;
