Noisy Stepper Motor
Posted: Tue Jul 19, 2022 1:46 pm
I purchased a common stepper motor for a project (35BYJ46). A person with normal hearing
could not tell you if the motor was on or off.
After several weeks of quiet operation it got noisy. As it completes a cycle, it makes a one or
or two second noise. It sounds something like a peanut shell being crushed.
I've quieted other small motors with grease. Using a Dremel tool you carefully grind the tabs
holding the motor case together. I packed 35BYJ46 with waterproof grease and reassembled
the case with dabs of cyanoacrylate adhesive.
The stepper motor ran completely quiet for several days. Unfortunately, the peanut shell crushing
sound returned.
Stepper motor 35BYJ46 is manufactured by numerous companies. Is there a brand or manufacturer
that makes top quality steppers? Maybe I can buy one that will stay quiet.
