Gears for Stepper Motor Shafts - Arduino Forum
2011年1月27日 · Hi, I am new to mechanics, and have bought the following stepper from digikey: The shaft is 1.5mm in diameter, and I would like to place a gear on the shaft. Can someone point me where I can buy gears that I can press fit or attach in some manner to a shaft of this size. I am not overly concerned with the number of teeth as I will be adding other gears to get the right step that I am looking ...
Robot arm stepper motor? - Motors, Mechanics, Power and CNC
2015年12月31日 · A stepper motor will move just as many steps as you tell it. That could be 1 or 7,000. And you can have as long an interval as you like between steps. What you may want to consider is the fact that stepper motors are very inefficient and not suited to battery power unless you are happy with heavy batteries.

2015年4月25日 · If the gears are not subjected to much torque, you can force a thin rod or piece of wire into the gear hub where the flat side of the "D" is located. Paul Robin2 April 26, 2015, 8:00am
Stepper motors with gears? "Star Tracker" - Arduino Forum
2020年9月29日 · I can however find planetary gears (would not be required as backlash is not a problem with such a setup) for some (larger) stepper motors at ridicioulsy high price levels with ratios of up to 1:1000. I also can find configurable "toy"-gears (all plastics) on the dirt-cheap end even exceeding 1:10000.
Where do I get gears for stepper motors with double-flat shafts?
2016年10月3日 · I bought 6 of these stepper motors for a robotics competition, but I can't find any gears that will fit the shaft type. I've added an image of the stepper. I also found this thing but I really need to use amazon. I think the shaft is called double-flat.
How to connect to the shaft of a stepper motor - Motors, …
2011年12月24日 · Hi I am trying to figure out how to connect parts to a stepper motor. The shaft of the motor I have seems to have a standard head with teeth. Is there some kind of standard bolt or clamp that makes it possible to connect other parts to these motors? I am trying to create a lazy Susan spinning table and I need to figure out how to connect the motor to the ball Bering assembly of the table. I ...
Attaching gears to motors and mounting motors - Arduino Forum
2015年1月27日 · As makerbots use stepper motors they come predrilled for 5mm stepper motors. Industrial suppliers will charge much more but they are out there. Looking at that chess machine, it works was probably cheap but a bit kludgy maybe , those gears look like …

2021年10月18日 · Hi! I would like to know where I could get plastic gears with a hole that fits the shft of the stepper motor which I attach in the image (I indicate the measurements of the shaft). I need a pinion gear with a 0.5 module, a pinion about 10-20 teeth and a sprocket of 40 teeth approximately. Thank you!
Geared Stepper Motor - Motors, Mechanics, Power and CNC
2011年9月11日 · I just received a new 10-pk of these 28BYJ-48 5VDC stepper motors and tested one to see if maybe a different manufacturer would use a slightly different gear ratio, some being 4096:1 and some being 4075.7728... I set the stepper motor sketch up so that it rotates for 4076 steps, pauses for 3 seconds, then repeats; a period of about 15.3 seconds.
Get high torque out of stepper motor - Motors ... - Arduino Forum
2022年2月2日 · I have a project where I need to lift about 2 kg about 15 cm above the ground with a stepper motor. I understand the holding torque can be calculated force times distance. So that would give me holding torque of: 2kg x 10N x 0.15 = 3 Nm Is this correct? These kind of steppers are however pretty expensive and since I need around 15 pcs of them I need to look for some cheaper options. Are there ...
