What are the advantages and disadvantages of stepping motors? What occasion is it suitable for?

1. The rotation angle of the motor is proportional to the number of pulses;

2. When the motor stops running (when the winding is excited), the torque is maximum;

3. Because the accuracy of each step is 3%-5%, and the error of one step will not accumulate to the next, it has good position accuracy and motion repeatability;

4. Excellent start-stop and reverse response;

5. Because there is no brush, the reliability is high, so the life of the motor only depends on the life of the bearing;

6. The response of the motor is only determined by the digital input pulse, so open-loop control can be adopted, which makes the structure of the motor simpler and the control cost lower;

7. Just connect the load directly to the rotating shaft of the motor, and it can rotate synchronously at a very low speed.

8. Because the speed is proportional to the pulse frequency, the speed range is very wide.

Disadvantages:

1. If it is not properly controlled, it is easy to produce * * * vibration;

2. It is difficult to run to a higher speed.

Mainly applicable to:

1. Stepping motors are mainly used in some occasions with positioning requirements, such as table dragging of wire cutting, table (hole positioning) of wool planting machine, packaging machine (fixed length), etc., which are basically used in positioning occasions;

Secondly, it is widely used in ATM machines, inkjet printers, engraving machines, photo printers, spraying equipment, medical instruments and equipment, computer peripherals and mass storage equipment, precision instruments, industrial control systems, office automation, robots and other fields, especially suitable for applications requiring stable operation, low noise, fast response, long life and large output torque;

Thirdly, stepping motors are widely used in computerized embroidery machines and other textile machinery and equipment. This kind of stepping motor is characterized by small torque, fast response speed when starting frequently, low running noise, stable operation, good control performance and low comprehensive cost.

Generally speaking, stepping motor has the characteristics of small inertia, high positioning accuracy, no accumulated error and simple control, and is widely used in mechatronics products.
