A brief introduction and application characteristics of stepping motor. Stepping motor is an open-loop control motor, which uses pulse control signals to convert it into Displacement. It is a motor capable of finely controlling displacement, due to many subdivision functions, it can realize very small stepping angular displacement and high control precision, which is the unique advantage of stepping motors. We often see that stepping motors are running in short distances, however, the back and forth work is very frequent, so the stepping motor is not suitable for long-term rotation in the same direction. . Application characteristics of stepper motor 1. When the stepper motor is running, the surface temperature is very high, but it does not affect its use, because of the internal magnetic material; 2. The driving signal the driving signal must be a pulse signal and does not need a feedback signal, namely the so-called open loop control; 3. Changing the transformation sequence of pulses can change the rotation direction of the stepping motor; 4, stepping motor speed should not be too fast, not suitable for high-speed occasions; 5. The accuracy of a general stepping motor is 3-5% or so; 6. Stepping motors have good emergency stop and inversion characteristics, which are incomparable to other motors; 7. When selecting a stepping motor, in principle, the motor is selected first and then the driver is selected. If the moment of inertia is large, a larger stepping motor is used; 8. The stepping motor and the whole machine sometimes produce resonance phenomenon, which is one of its shortcomings. Therefore, when avoiding this working point, the voltage or current can be changed to solve it; Related reading: Stepping Motor and its driving circuit, open loop control principle of stepping motor TAG stepping motor
