这些是真实发生的事情吗？为什么听起来感觉这么虚幻啊？哈哈哈···睡觉去····

In the current automated machine, stepper motors have a very wide range of applications.
    Such as automatic machine feeding mechanism, in addition to the general machinery sector drawing blanks, positioning pin machinery sector,gear motor, the stepper motor feed mechanism is also quite popular with more and more.
    The feed mechanism during stepper motor design,dc motor, the calculation of its ratchet operator probably has more trouble.
    Below is a brief talk about their calculation.
    We know that by stepping motor pulse roughly 0.09,extruder,0.18,planetary gear motor,0.36,0.72 degree angle.
    It must ratchet teeth on the circumference (360 degrees) of the integer. Therefore,planetary gearbox, the angle between its two teeth,extrusion machine, must be the pulse point of the integer.
    In general,gear box, the angle of 7.2 degrees election; 14.4 degrees,plastic extruder, the number of teeth is 25 teeth; 50 teeth.
    Ratchet the calculation of the radius, the rule is: R is larger, the greater the arc length; R smaller, the smaller the arc length. The formula is L = (лR * N °) / 180 ° N ° says: The two sub-degree angle between teeth; which L said: arc length, that is, PITCH value; л said: pi (the better to take the decimal point The more accurate, 3.1415926).
