Motor runaway conditions not only increase expenses, but can also create dangerous situations. The incorporation of a Velocity Limited Torque Mode function on a servo system can mitigate runaway motor ...

Disturbance rejection, like command tracking, is usually expressed graphically. The graphs, called disturbance rejection plots, show the effect of PIV gains on disturbance torque applied to the shaft ...

This article originally appeared on Heidenhain.us and has been published here with permission. Servo motors are electric motors that let engineers and designers precisely control position, velocity ...

Once the control method of choice only in high-performance industrial ac-servo drives, FOC (field-oriented control) is finding its way into lower end industrial and many appliance applications with ...

Stepper motors resemble servo motors in that both types are characterized by an ability to rotate a partial turn and then stop for any interval with or without holding torque. In addition, both motor ...
