Motion-control architecture appears to be compact and simple. But in reality, the individual servo loops-current, velocity and position-have been traditionally shared between a drive and a separate ...

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 ...

Sponsored by Texas Instruments: Single-chip microcontrollers geared to servo and other industrial/EV control applications help engineers cost-effectively design multiple-axis systems. As manufacturing ...

The AECS 35/3 sensorless servo amplifier provides closed-loop velocity control via sensing back EMF of the motor or by commutation only. Designed for brushless motors without sensors, the amplifier ...

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 ...

Combining a high-torque step motor with an on-board drive, encoder, controller and closed-loop servo software into a single package, the integrated motors save on space, wiring, and cost over ...

It is an engineering truism that there is no such thing as a perfect solution—just the best solution for the problem at hand. That holds particularly true for servo motors and stepper motors. Both are ...
