STEPPERONLINE27:1 Planetary Gearbox High Torque Nema 17 Stepper Motor 3D Printer DIY Camera

Realmente sorprendido por el producto, la calidad y precio, muy buen costo beneficio en el producto.

The stepper motor with 27:1 planetary gearbox arrived in just two days from the time of my order.The motor/gearbox was shipped in a very good box with very good foam padding.The motor was brand-new as advertised and looked very nice.I tried the motor out on my system using a Raspberry Pi 3 B+ with a simple Python code. I was able to drive the geared motor with an L298 driver. With just 5 volts on the driver, I could drive the stepper motor.The motor behaved exactly as a bipolar stepper motor is supposed to behave and the shaft rotated quite smoothly, using 0.05 seconds for each pulse that went from the GPIO board (four outputs pins ) to the four input pins of the driver. Very impressive system for around 40 dollars.If you do not have time to build a planetary gearbox for your NEMA 17 stepper motors, then this will be perfect for you.I am rotating a piece of apparatus that weighs about 5 -7 oz , that has a relatively small moment of inertia. This STEPPERLINE motor worked great for me. Thank you.

Used for a clay extruder. Very quiet and dependable. I just put it into service recently and this thing is strong enough to pull stumps!I was concerned with it having the nylon gears and they do offer a metal screw model for more $ but so far so good. It’s nice to know I have an option...

I am using several of these to open/close doors in a display. The gear ratio is high enough to get good acceleration control and low enough that they can be back driven if someone moves a door manually. Original order of 12 was lost in shipping but quickly replaced.

Nice high torque but the small amount of gear slop made it un useable for the application I needed.
