Stepper motorized syringe pump

Syringe pump How to control syringe pump using stepper motor? Arduino, easy driver and stepper motor, joystick and limit switch? Stepper moves CW and CCW When hits limit switch 1 turns direction and again when hits limit switch 2 turns to other side When limit switches are pushed in the same time to control the relay to use the valves Speed control, so it will be able to basically control volume p...

MPG Pendant, Mach3 or Mach4

MPG Pendant What is MPG Pendant? MPG Pendant stands for Manual Pulse Generator Pendant or Handwheel(Chinese translation?) A manual pulse generator (MPG) is a device for generating electrical pulses (short bursts of low current) in electronic systems under the control of a human operator (manually), as opposed to the pulses automatically generated by software. MPGs are used on computer numerically ...

Selection of peristaltic pump system

Stepper Motor Peristaltic Pump Peristaltic pump system is mainly divided into three parts: peristaltic pump head, peristaltic pump pipe and peristaltic pump driver. 1. Selection of pump heads. 1, the pump head is divided into single channel and multi-channel transport fluid. 2. Hose should be replaced easily. 3, there is easy to fix the hose. 4. Fine tuning ratchet to change the pressure pipe gap ...

Teflon coated lead screw

Teflon coated lead screw 1. Stainless steel lead screws why teflon coating is applied? 2. Teflon or PTFE solid lubricant get rid of what problems? 3. Teflon coated lead screw threaded linear stepper motor. Lead screws are one of the most common and cost-effective tools used to convert rotary motion into linear motion. Advanced materials and coatings allow them to be used in a multitude of applicat...

What is Simulink?

Simulink, an add-on product to MATLAB, provides an interactive, graphical environment for modeling, simulating, and analyzing of dynamic systems. It enables rapid construction of virtual prototypes to explore design concepts at any level of detail with minimal effort. For modeling, Simulink provides a graphical user interface (GUI) for building models as block diagrams. It includes a comprehensive...


Timing Pulley Classification by Mounting Beginning with the most inexpensive options, good for fitting into tight budget scenarios where the load is not a big constraint, set screws provide security for only the lowest loads. These use friction of the set screw against a set screw flat on the shaft for their holding power. With the addition of a keyway, they can provide a mounting solution for low...

ACME vs Trapezoidal Threads

ACME and trapezoidal threaded products appear similar at a glance. In fact, these two threads were developed around the same time and are more similar than different. What is the difference between ACME thread and trapezoidal thread, and which should you choose? Until the late 1800s, square threads were in common use for heavy loads and motion transfer applications. There were two problems with sq...

The world of Timing Belts

Timing belts are parts of synchronous drives which represent an important category of drives. Characteristically, these drives employ the positive engagement of two sets of meshing teeth. Hence, they do not slip and there is no relative motion between the two elements in mesh. Due to this feature, different parts of the drive will maintain a constant speed ratio or even a permanent relative positi...

RC Servo Spline Chart

How many splines does your RC Servo have? Here is a listing to help you to select the right horn for the RC Servo. Pay close attention to your servo, some servos are rebadged servos from other brands. This is the case of the Hobbico CS-170 that uses 24 splines (Hitec) instead of 25 splines traditionally found on Hobbico servos. Ace/Thunder: 25T Airtronics: 23T Blue Bird: 25T Cirrus: 25T Duratrax: ...

Kicad, Altium, OrCad vs Eagle

KiCad is a free software suite for electronic design automation. It facilitates the design of schematics for electronic circuits and their conversion to PCB designs. KiCad was originally developed by Jean-Pierre Charras. It features an integrated environment for schematic capture and PCB layout design. Tools exist within the package to create a bill of materials, artwork, Gerber files, and 3D view...
