MIDI controlled nearly silent stepper motor interface

Can control 6 stepper motors

USB MIDI with Teensy LC and Silent Step Stick stepper drivers

This is a volume test for a few stepper motors.

For this test I used a MIDI to stepper motor interface that I made using a Teensy and Silent-Step-Stick stepper motor drivers in stealth mode. Note that in silent mode, stepper motors are much weaker. I chose those motors because they are all inside the SilentStepStick stepper driver range, and because they can run at 12V. I decided that I wanted motors that can run at 12V because it is really easy to find 12V power supplies.


Nema 17 Stepper Motor 17HS4401S
My opinion: silent enough if isolated, but not strong enough for most purpose.

Nema 17 Bipolar Step Motor 1A 13Ncm(18.4oz.in) 17HS08-1004S
My opinion: this one too loud to make anything close to silent. Really really weak too.

Nema 17 Stepper Motor 34mm 12V 0.4A 26Ncm(37oz.in) 17HS13-0404S
My opinion: silent enough if isolated, but not strong enough for most purpose.

Nema 17 Bipolar Stepper Motor 0.28A 36Ncm(51oz.in) 17HS16-0284S
My opinion, silentest I tested. Relatively weak, but usable. I noted that it is too the one that needs the lowest current.

Nema 17 60Ncm(85oz.in) 0.64A Bipolar Stepper Motor 17HS24-0644S
My opinion: silent enough if isolated, strong enough for most purpose, but big.

Nema 23 CNC Stepper Motor 0.88A 0.6Nm(85oz.in) 23HS16-0884S
My opinion: silent enough if isolated, strongest I tested, only one (but the geared one) that I can not stop with my fingers. Big

Gear Ratio 100:1 Planetary Gearbox With Nema 11 Stepper Motor 11HS20-0674S-PG100
My opinion: silent enough if isolated, but not that silent. Strong but really slow.


I found most of those steppers on omc-stepperonline.com
