The International Electrotechnical Commission (IEC) defines a servo device as “an adjustable-speed AC power drive system that includes an AC motor integrated by feedback, a converter, and control, ...

As a Machine Design article notes, the key to effectively specifying the right step motor is to find the balance between efficient operations and performance limitations. “[The term “Maximize torque ...

A growing number of manufacturers are saving time and money by testing, diagnosing and even repairing servo motors in-house. We look at the expanded role of encoder test systems and present one ...

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 ...

Increasingly elaborate Rube Goldberg schemes for controlling step-motors have developed over the years that try to pace stepping to avoid missteps. This direction of development is fundamentally ...
