Packing Machine in a pack process the feed screw rotation

Pushing back against calculate

Stepper motor to go 1.092s, and go 1092

And because the steep angle

So turn the stepper motor

And screw driven by a stepper motor rotation after a 1:3 spin-down ,

Rotational speed of the screw

The number of revolutions per minute of the screw

Revolutions per minute, the number of stepper motor :

At this point , the stepper motor to go one step , the mass of the screw cutting

Packing Machine In a pack process, the feed screw rotation 1.092 seconds , 0.908 seconds stepper motor stops rotating , manually Packing Machine, Packing Machine when the material is 500g / package , we can use the following method : We cannot changing the number of steps of the stepper motor , so that the microcontroller program is not required to change , only the pitch of the screw and the screw diameter .

We take the solution of equations

= 0.0004

S = 100mm

At this point , the stepper motor is still walking 1092 steps , each step should be the material for the

May also be used to change the number of steps of the stepper motor , without changing the pitch .

3.2 motor selection

3.2.1 Description of the stepper motor

Stepper motor is an electrical pulse signal is converted into a corresponding angular displacement or linear displacement of the electromechanical actuator , an electrical pulse whenever the input , it will turn a fixed angle , this angle is called the step angle , referred to as step . Pulse input one by one , step by step, the motor will rotate the stepper motor then lends named .
