Brief Introduction of Technical Characteristics

General technical characteristics

● 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. When the motor has high working efficiency and low noise;

● It is best not to use the full-step state for the stepping motor, because the vibration is large in the full-step state;

● 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 (recommendation: 42 and below motors use 12-24V, 57 motors use DC 24V-48V, 86 use DC 48-80V, 110 The motor adopts higher than DC 80V)

● For loads with large moments of inertia, a large frame size motor should be selected;

● When the motor is in a relatively high-speed or large inertia load, it generally does not start at the working speed, but uses a gradual frequency increase to increase the speed. First, the motor does not lose step, and second, it can reduce the noise and improve the positioning accuracy of the stop;

● For high precision, it should be solved by mechanically decelerating, increasing the motor speed, or using a driver with a high subdivision number;

● The motor should not work in the vibration zone, if necessary, it can be solved by changing the voltage, current or adding some damping;

● When the motor works below 600PPS (0.9 degrees), it should be driven by small current, large inductance, and low voltage.

Mechanical technical characteristics

● When installing/removing the shaft end of a stepping motor with a coupling part, do not directly hit the shaft end with a hammer. (The hammer hits the shaft end directly, and the encoder at the other end of the stepper motor shaft may be damaged);

● Try to align the shaft ends to the best condition to ensure good concentricity, otherwise vibration may occur, the bearing may be damaged, and the shaft may even be broken;

● The motor can be used in places that will be attacked by water or oil drops, but it is not completely waterproof or oil-proof. The default protection level is IP54. Therefore, the motor should not be placed or used in an environment corroded by water or oil (if necessary For special protection level, please contact us!);

● If the motor is connected to a reduction gear, oil seals should be added when using a stepper motor to prevent the reduction gear from entering the stepper motor;

● Do not immerse the motor cable in oil or water. Ensure that the cable is not subjected to moment or vertical load due to external bending force or its own weight, especially at the cable outlet or connection.

● When the motor is moving, the cable (that is, the one configured with the motor) should be firmly fixed to a stationary part (relative to the motor) and an additional cable loaded in the cable support should be used to delay it, so that the bending stress Can be reduced to the minimum. The radius of the cable elbow should be as large as possible
