Stepper motors are whistling and irregular when moving. The whistling is very sharp, a bit like the buzzer sound, absolutely not mechanical friction sound. Please understand a friend doubts, very grateful!
Stepper motor at high speed is howling, and if your speed is not high, that is the problem of driving
E. on the motor shaft with magnetic damper, the market already has this kind of product, but the mechanical structure changes greatly. The East, SANYO and other motors have standard productsThe current F. motor set is too large, the need to drive through the current value is set as the fitness function.The big reason is the problem of driving the controller
C. is replaced by stepping motors with smaller stepping angles, such as three-phase or five phase stepping motors;D. replaced by AC servo motor, almost completely overcome vibration and noise, but the cost is higher;
The vibration and noise of stepping motor at low speed are its inherent disadvantages, and the following methods can be used to overcome them:A., such as stepping motors, work just in resonance, avoiding mechanical resonances by varying mechanical ratios such as speed reduction;
