What are the advantages and disadvantages of stepping motor? What occasion does it apply to?
Disadvantages: If the control is not easy to generate resonance; It is difficult to operate at a high speed. The main application is: First, the stepper motor is mainly used in some places that have requirements of positioning requirements, such as: wire cutting workbench drag, flocking machine workbench (pores), packaging machine (length), basically involves positioning occasions are applied;
Second, widely used in the ATM machine, spraying machine, carving machine, photo machine, spraying equipment, medical instrument and equipment, computer peripherals and mass storage equipment, precision instruments, industrial control system, office automation, robots and other fields, especially suitable for smooth operation, low noise, fast response, long service life, high output torque applications; Third, step motor in computerized embroidery machine is widely used in textile machinery and equipment, such as the characteristics of this kind of stepper motor is to keep the torque is not high, frequent start the reaction speed, low noise, smooth operation, operation control performance is good, the machine cost is low; In general, the characteristics of low inertia, high positioning accuracy, no accumulated error and simple control are widely used in the products of electromechanical integration.
The maximum torque when the motor is suspended (when the winding is exciting); Because the accuracy of each step is 3 to 5 percent, and does not accumulate the error of one step to the next, it has better position accuracy and motion repeatability. Excellent stop and reverse response; Because there is no brush, the reliability is high, so the life of the motor depends only on the life of the bearing. 6. The response of the motor is only determined by digital input pulses, and thus can be used in a open loop control, which makes the structure of the machine is relatively simple and low cost control; Simply connecting the load directly to the rotor of the motor can also rotate at a very low speed. Because speed is proportional to pulse frequency, there is a wide range of speed.
