Shanghai four macros below the stepper motor will be for us about what is the advantages and disadvantages of stepper motor. First is advantages, advantages: there are eight 1. Motor rotation Angle is proportional to the pulse number; 2. Time has a maximum torque motor stalling (When winding excitation); 3. Due to the precision of each step in 3%5%, and would not step error piled up to the next so have a good position precision and the repeatability of movement; 4. Excellent start-stop and rotary echo; 5. Since there is no brush, high reliability, so the motor life spans only depends on the bearing life; 6. Motor decided only by the digital input pulse echo, can therefore choose open loop control, which makes the motor structure is simple and manipulation of the capital is relatively low; 7. Just will be directly connected to the shaft of the motor load can also be extremely low speed synchronous rotation. 8. Because speed is proportional to the pulse frequency, the speed of the there is a wide scale. And then the disadvantages: 1. If the manipulation of the wrong prone to resonance; 2. Hard work to a higher speed. Open loop control, step motor is one of the most meaning strengths in open loop system can accomplish accurate control. Open-loop control means don't need about (Rotor)Azimuth response information. This kind of control to avoid the use of precious sensors and reaction equipment, such as optical encoder by only having to the step of the input pulse will be able to know you (Rotor)The azimuth. The above content for Shanghai four questions encountered in macro stepper motor work collection, reference, if you have any questions please timely communication, correct. the main products: stepper motor, brushless motor, servo motor, stepping motor drive, brake motor, linear motor and other kinds of models of the stepper motor, welcome to inquire.
