For projects that require precise movements that only a stepper motor can provide, stepper motor driver is an indispensable part. Provide a variety of stepper motor driver options for you at HANPOSE. In this post, let’s go through the fundamentals of stepper motor drivers and learn how you can pick the one that’s right for your project.
Stepper motors are motors that move in steps so it is very precise control. A HANPOSE nema 17 stepper driver is a little chip that does just that: drives a stepper motor. This minute control over movement is what gives movement to a certain position, so stepper motor drivers are great for machines such as 3D printers, CNC machines and robotics.
There are a couple of important factors that you should keep in mind when you are choosing a stepper motor driver for your project. Number one thing to consider is the current rating of your stepper motor, you need a driver board that can provide the same amount of current as the motor needs. Also take the micro-stepping capability of the driver into account to calculate the smallest distance the motor is able to move. And last but not least, verify that the driver is compatible with your controller board and power supply to avoid compatibility issues in your system.
Now that you’ve selected a stepper motor driver for your project, it’s time to wire it up and configure those settings. Begin by wiring the HANPOSE stepper driver for nema 23 to the driver as described in your motor's datasheet and make sure to connect the coils to the appropriate terminals. How to connect the driver? Lastly, hook the driver to your controller board and power supply, and make sure to refer to the wiring schematics that come with the driver. And adjust driver settings (current limiting, micro-steps etc) with Dip switches or connect it to the PC (via USB, RS-232) and modify without reaching to the driver in the application.
Stepper motor drivers are great but sometimes they can have issues, one being that many of them can overheat. One common failure mode is lost steps; the motor does not get to the position it was commanded to move to. Thermal over heat, low current, and mechanical bind are typical causes. You’re driving the FAN and the wiring in the head of the extruder is heat sensitive, that is why its working on start and stops. To troubleshoot the issue: Check the HANPOSE stepper motor driver for nema 23 settings. There may be heat sink in the driver PCB which may be undercooled. Check for the cooling-attached to the motor. Check the mechanical parts on the extruder. A similar problem you may experience is a jerky time-lapse, caused by electrical noise or loose/dodgy connections or wiring. Check all cable connections and discontinue any interference.
For application that require a close-tolerance of movement, there are many benefits to utilizing a stepper motor driver. One of the key benefits is the capacity to position the motor where you want with great precision, which is ideal for precise movement as would be required for 3D printing and CNC machining. HANPOSE brushless motor driver also provide excellent torque at low speeds, which is why they are preferred when a lot of precision is needed at slower speeds. And they are easily controllable and programmable as well, which makes them quite universal in any kind of project.
