How To Attach Motors To Your Hobby Project For Wheels, Gears, Shafts

This video tutorial explains how to attach motors to your hobby project, for example, attaching a motor to a wheel, gear, or shaft.

Opt for motors that have metal gears inside rather than plastic gears inside; these are less likely to break and are more durable, especially for high torque or if you're new to motors.
Make sure to check the Stall Torque, and the operating speed (rotation per minute, rpm). If the stall torque is low, your motor may not have the ability to turn against high forces or high friction. Your maximum power for the motor occurs at half of the no-load speed, and at half of the stall torque. Some motors are optimized for speed, whereas others are optimized for torque. No-load speed means the speed of motor with nothing attached. Stall torque means the torque when you have such a heavy load attached that the motor "stalls" (stops rotating).

always puzzled me, thanks for the explanation!

[@thomaskinsman8662]

Thank you! You are an inspiration!

[@eggblight_ganon]

Thank you, this helped me build my project!

[@Indianarailproductions]

Thank you! I’m making a railroad crossing signal, which requires many gears inside the mechanism. Again, thank you!

thank you!

Very helpful. It's hard to find useful video on these niche topics.
I was trying to create a elliptical wheel to vibrate a object resting on it by just connecting a wheel off-center to a stepper motor

That's great! Feel free to let me know if you have other video tutorial topic requests

I’m trying to create an automatic door closer and want to attach a shaft to a long plank that will exert force on my door. Do you recommend a universal mounting hub?

[@taliakellegg5978]

my motor has a smooth drift shaft and it's so annoying trying to attach an axle to it

[@boheatherbowman7636]

Did you end up finding a way to attach the axle? For smooth shafts, I tend grind down a small section of the shaft to be flat in a section and then use a set screw to hold against it. The best is when it's a hex-shaped shaft so a lathe can grind down one section to be smooth cylindrically and use the hex-shaped end for attaching to the wheel, axle, etc. Other options are shaft collars, or perhaps you could try tapping the ends so they have threads.

@@boheatherbowman7636 thank you! both of those sounds like a better solution tha n what i did. i use a lot of heat sinks to hold them together and it worked because it was pretty much just a fan with no real resistance
