What is the difference between the stepper motor driver and the quiescent current setting to ON or OFF?
Two, induction type stepper motor working principle (I) response type stepper motor principle, because the reaction stepper motor working principle is relatively simple. The following describes the principle of three-phase reactive stepping motor.1, structure: uniformly distributed rotor with many small teeth, the teeth of the stator with three excitation winding, the geometric axis of the rotor tooth axis in orderwere staggered. 0, the 1/3, the 2/3, (two adjacent rotor tooth axis was the distance between the pitch to the said, A and 1) teeth aligned, B and 2 1/3 at right staggered tooth, C and 3 2/3 at right staggered tooth, 5 teeth and A'aligned (A' is A, the tooth the 5 is the tooth 1) below is out of the rotor:
Stepper motor principle descriptionThe 1. step motor is an open loop control element that changes the electrical pulse signal into angular displacement or linear displacement. In the case of non overloaded, the motor speed and stop position depends only on the pulse frequency and pulse number, regardless of load changes, namely to add a pulse motor, the motor is turned to a step angle. The existence of this linear relationship, and stepper motor only periodic error and accumulated error etc.. It is very simple to control by stepping motor in the control field of speed, position and so on. Although the stepper motor has been widely used, but stepper motors can not be like ordinary DC motors, AC motors in the regular use. It must be composed of double ring pulse signal, power drive circuit and so on, and the control system can be used. Therefore, it is not easy to make good use of stepping motor. It involves many specialized knowledge, such as mechanical, electrical, electronic and computer. At present, the production of stepper motor manufacturers are indeed many, but with professional and technical personnel, can develop their own development, manufacturers are very few, most of the manufacturers, only twenty people, even the most basic equipment are not. Only in a blind imitation stage. This will give the household a lot of trouble in the selection and use of the product. As stated above, we have decided to take an extensive induction stepper motor as an example. Describe its basic working principle. I hope it will help the users in the selection, use and improvement of the whole machine.
