5、ntrolling the system lowers. 2、What is a stepper motor： Stepper motor is a kind of electrical pulses into angular displacement of the implementing agency. Popular little lesson: When the driver receives a step pulse signal, it will drive a stepper motor to set the direction of rotation at a fixed an

6、gle (and the step angle). You can control the number of pulses to control the angular displacement, so as to achieve accurate positioning purposes; the same time you can control the pulse frequency to control the motor rotation speed and acceleration, to achieve speed control purposes. What kinds of

7、 stepper motor sub-：In three stepper motors: permanent magnet (PM), reactive (VR) and hybrid (HB) permanent magnet stepper usually two-phase, torque, and smaller, step angle of 7.5 degrees or the general 15 degrees; reaction step is generally three-phase, can achieve high torque output, step angle o

8、f 1.5 degrees is generally, but the noise and vibration are large. 80 countries in Europe and America have been eliminated; hybrid stepper is a mix of permanent magnet and reactive advantages. It consists of two phases and the five-phase: two-phase step angle of 1.8 degrees while the general five-ph

11、ineering outward appearance allow of the tallest temperature should be decided by small back with electrical engineering magnetism material and order; Speak generally, the magnetism material backs to order all above have in 130 C an of even be up to 200C above, so tread completely normal into the el

12、ectrical engineering outward appearance temperature in 80-90C. （3）、dints which enter electrical engineering would with turn to go up but descend soon，While treading to turn to move into the electrical engineering, electrical engineering each electricity feeling which round a set mutually will become

13、 one anti- to electromotive force; The frequency is more high, anti- to electromotive force more big ，big in its function, the electrical engineering enlarges with the frequency(or speed) but mutually the electric current let up, causing the dint descend thus. （4）、 can revolve normally when 4 enter

14、electrical engineering low speed, but if high in certain the speed cant start, and the companion have a roar the interjection tread to have a technique parameter into the electrical engineering: empty carry start frequency, then tread into electrical engineering at empty carry under circumstance can

15、 start normally of pulse frequency, if the pulse frequency is high in should be worth., The electrical engineering cant start normally, the possible occurrence throws a step or blocks up to turn. Under the situation that there is one load, the start frequency should be much lower if want to make the

16、 electrical engineering attain high speed to turn to move, the pulse frequency should have an acceleration process, then start the frequency is lower, then press certain acceleration to rise the high hoped. Tread to show the characteristics of with it into the electric motor, turn ages of manufactur

17、ing to develop important use to accompany with in the numeral small together of numeral turn technical of development and tread into the electrical engineering technical exaltation，tread will get an application in more realms into the electrical engineering. 4、enter an electrical engineering control

18、 system to constitute： Tread is a kind of performance organization that will give or get an electric shock a pulse conversion to move for the Cape into the electrical engineering. When tread to receive to a pulse signal into the actuator, it drives a step to press the direction of enactment to turn

19、to move an angle for fixing to be called tread to be apart from Cape into the electrical engineering, it revolves one-step circulate with the fixed angle one step. Can pass control pulse piece to control a Cape to move to attain the purpose of assurance most and thus; Can pass control pulse frequenc
