42 Stepping Motor is a kind of induction motor, its working principle is the use of electronic circuit, direct current (dc) into time-sharing power supply, multiphase sequential control current, in this current for stepper motor power supply, step motor to work properly, is time-sharing power supply for step motor drive, multiphase timing controller.
3D printers are dominated by PC power supplies, main control circuit, stepper motor and control circuit, high temperature nozzle and workpiece the substrates of this a few parts. Through the main circuit board will process after the 3 d model file into the X, Y, Z axis and nozzle feed stepper motor data, to the four stepper motor control circuit to control, and then give in motor control circuit control artifacts the substrate of the x-y plane, nozzle vertical movement and nozzle feed speed, more accurate melts the raw material for high temperature nozzle spray layer by layer on the workpiece after the output of the substrate, forming the final entity model. 42 Stepping Motor control the raw material after high temperature nozzle will melt spray output substrate at 110 ℃, the output of the model base plate is fixed, and then began to print one by one.
42 Stepping Motor have the most revolutionary features, It has a high output torque, high response speed, high interval angular accuracy, low noise, low energy consumption and some other features. It adopts special structure, excellent material and advanced manufacturing process, adopts ac servo control principle, ac servo motor operation characteristics. Can be controlled by controlling the pulse number of angular displacement, so as to achieve the purpose of accurate positioning; As well as by controlling the pulse frequency to control motor rotation speed and acceleration, so as to achieve the purpose of regulating. Stepper motor can be as a control with special motor, using the characteristics of no accumulation error (accuracy of 100%), widely used in all kinds of open loop control.
