• BTW, without the damper, the stepper motor made typical stepper motor noises and could only run at about half speed before stalling. With the damper, it was dead quiet at any speed. Makes sense as a stepper motor has terrific cogging, ie., it has preferred positions caused by the interactions of the magnetic field and the stator/rotor design.

Stepper motor making high pitched noise

A 2 phase motor would need 4 half bridges, while a 3-phase motor only needs 3. 2-phase stepper motors seem to be a bit cheaper and more common than 3-phase motors. I might put 4 of the BTS7960 chips on it and make the 2 vs 3 phase a software option.

Stepper motors are mostly used in open-loop systems. This means that there is no feedback on the current position of the shaft. So you only keep track of steps and rely on stepper motor rotation precision. They are great on the precise low-speed operation, are reliable as there are no brushes.

Mechaduino is a board that sits on a regular stepper motor and turns it into a servo with a closed loop control of 0.1degree. The board supports lots of standard communication protocols, but the acceptance of regular stepper inputs make it extra interesting.

When I run the motor above certain speeds, in this case 4rev/sec, it produces a high frequency sort of whinny sound. It is a 4.5A motor and I am running it with 24V. If I run the motor at 48V, I am able to reduce the high frequency sound quite a bit, in fact I have to go up to 6rev/sec for it to be at audible/annoying levels. My initial guess is that at 48V the stepper is able generate more torque since the current in the coils is able to overcome back EMF and rise to higher levels than in 24V.

Ultrasound is high-pitched sound waves with frequencies higher than the audible limit of human hearing. Human ears can hear sound waves that vibrate in the range from about 20 times a second (a deep rumbling noise) to about 20,000 times a second (a high-pitched whistling). Oct 26, 2019 · The step size of the linear stepper motor is determined by the step angle of the motor and the pitch of the internally threaded nut and the lead screw. In order to ensure high working efficiency, there must be a certain degree of freedom between the rotor and the lead screw, which requires a certain gap between the two, which is about 0.03 to 0.08 mm axial clearance (also called backlash).
