1. High precision and a tiny step angle
2. The number of pole pairs is equal to the number of rotor teeth, which can be varied according to requirements.
3. Because the winding inductance varies slightly with rotor position, it is simple to provide the best operation management.
4. An axial magnetising magnetic circuit that employs a novel type of permanent magnet material with a high magnetic energy product improves motor performance.
5. The rotor magnet provides excitation; there is no discernible oscillation throughout the operating area.

Dynamical technological features

  1. Do not hit the shaft end of a stepping motor with a hammer when installing or removing it with a coupling part. (The hammer hits the shaft end directly, and the encoder at the other end of the stepper motor shaft may be destroyed).
  2. To achieve proper concentricity, try to align the shaft ends in the best condition possible; otherwise, vibration may occur, the bearing may be damaged, and the shaft may even be destroyed.
  3. The engine can be used in situations where water or oil drops may be present, although it is not totally waterproof or oil-proof. IP54 is the standard level of protection. As a result, the motor should not be put or utilised in a water or oil-corroded environment (if necessary). Please contact us if you require a higher level of protection!)When employing a stepper motor, oil seals should be inserted if the motor is coupled to a reduction gear to prevent the reduction gear from entering the stepper motor.
  4. Never submerge the motor cable in oil or water. Ascertain that the cable is not subjected to moment or vertical stress as a result of external bending force or its own weight. Particularly at the cable outlet or connector.
  5. When the motor is moving, the cable (that is, the one configured with the motor) should be firmly fixed to a stationary portion (relative to the motor), and an extra cable loaded in the cable support should be used to delay it, so that the bending stress is kept to a minimum. The radius of the cable elbow should be as wide as possible.
General technological features
  1. The stepping motor is utilised in low-speed situations where the speed does not exceed 1000 revolutions per minute (6666PPS at 0.9 degrees), preferably between 1000 and 3000PPS (0.9 degrees), and it can be used in conjunction with a decelerating device. When the motor is both efficient and quiet.
  2. Because the vibration is so high in the full-step condition, it is preferable not to use it for the stepping motor.
  3. The voltage value in the motor specification is not the volt value of the driving voltage. The exact driving voltage can be adjusted based on the stepper driver (recommendation: 42 and below motors use 12-24V, 57 motors use DC 24V-48V, 86 motors use DC 48-80V, 110 motors use DC 48-80V, 110 motors use DC 48-80V, 110 motors use DC 48-80V, The motor uses a voltage greater than DC 80V).
  4. A big frame size motor should be used for loads with high moments of inertia.
  5. When the motor is in a relatively high-speed or high inertia load, it normally does not start at the operating speed, but instead increases the speed gradually by increasing the frequency. First, the motor does not lose step, and second, it may reduce noise while improving stop positioning accuracy.
  6. It should be solved for high precision by mechanically decelerating, increasing the motor speed, or employing a driver with a high subdivision number.
  7. When the motor operates at less than 600PPS (0.9 degrees), it should be powered by a small current, a big inductance, and a low voltage.
  8. The motor should not operate in the vibration zone; if this is essential, it can be remedied by adjusting the voltage, current, or adding dampening.
