STXI Motion expands integrated closed-loop servo-stepper motor line
The stepIM NEMA 17 EtherCAT model from STXI Motion is the newest addition to the company’s family of integrated closed-loop servo stepper motors. The IP65-rated stepIM NEMA 17 delivers an efficient and economical solution for applications requiring the performance of a servo at the price of a stepper. “The new stepIM NEMA 17 closed-loop stepper […]
Why do stepper motors vibrate and what are ways to avoid or dampen vibrations?
With each discrete step that a stepper motor makes, the inertia of the system causes the motor to slightly overshoot (or undershoot) the intended step angle. The motor then oscillates, or “rings,” until it finally settles at the commanded position. If the frequency of these step-by-step oscillations is at or near the motor’s natural frequency, […]
When is the application of overvoltage safe (and common) for stepper motors?
For most types of motors, operating with a supply voltage that is higher than the rated voltage — referred to as overvoltage — can cause an increase in current, and heat, high enough to damage the coils and other motor components. But in some cases, a stepper motor can be operated at a voltage higher than rated […]
Why is RMS current important in stepper motor applications?
Most precision stepper motor applications — especially those in automation and motion control — use a control method referred to as microstepping, which creates a sinusoidal (or nearly sinusoidal) current waveform, rather than the square wave of current produced with typical full-step control. The current rating of a stepper motor depends on the amount of […]
